Reduced the size of MB_MODE_INFO Moved partition_bmi and partition_count out of MB_MODE_INFO and placed into MACROBLOCK. Also reduced the size of other members of the MB_MODE_INFO struct. For 1080p, the memory was reduced by 1,209,516 bytes. The decoder performance appeared to improve by 3% for the clip used. Note: The main goal for this change is to improve the decoder performance. The encoder will be revisited at a later date for further structure cleanup. Change-Id: I4733621292ee9cc3fffa4046cb3fd4d99bd14613

Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise. I have not attempted to make any changes to configure to do this automatically. Doing so will probably require the addition of new configure options. Many of the hooks for RTCD on ARM were already there, but a lot of the code had bit-rotted, and a good deal of the ARM-specific code is not integrated into the RTCD structs at all. I did not try to resolve the latter, merely to add the minimal amount of protection around them to allow RTCD to work. Those functions that were called based on an ifdef at the calling site were expanded to check the RTCD flags at that site, but they should be added to an RTCD struct somewhere in the future. The functions invoked with global function pointers still are, but these should be moved into an RTCD struct for thread safety (I believe every platform currently supported has atomic pointer stores, but this is not guaranteed). The encoder's boolhuff functions did not even have _c and armv7 suffixes, and the correct version was resolved at link time. The token packing functions did have appropriate suffixes, but the version was selected with a define, with no associated RTCD struct. However, for both of these, the only armv7 instruction they actually used was rbit, and this was completely superfluous, so I reworked them to avoid it. The only non-ARMv4 instruction remaining in them is clz, which is ARMv5 (not even ARMv5TE is required). Considering that there are no ARM-specific configs which are not at least ARMv5TE, I did not try to detect these at runtime, and simply enable them for ARMv5 and above. Finally, the NEON register saving code was completely non-reentrant, since it saved the registers to a global, static variable. I moved the storage for this onto the stack. A single binary built with this code was tested on an ARM11 (ARMv6) and a Cortex A8 (ARMv7 w/NEON), for both the encoder and decoder, and produced identical output, while using the correct accelerated functions on each. I did not test on any earlier processors. Change-Id: I45cbd63a614f4554c3b325c45d46c0806f009eaa

Change to inter_minq table. The inter_minq table controls the range of quantizers available for a particular frame in two pass relative to a max Q value. The changes reduces the range somewhat. The effect of this was a small increase (0.3% average) in psnr for the test set but it should also help encode speed somewhat for higher quality modes as it will reduce the number of iterations in the recode loop. The change damps the range of quantizers available locally within a section of a clip and should therefore help keep quality more uniform. If there is systematic overshoot or undershoot the range can shift gradually to accommodate. However, there is some increased risk of overshoot or undershoot against the target bit rate in VBR mode and this risk will be more pronounced for short clips.

Fix loopfilter delta zero transitions Loopfilter deltas are initialized to zero on keyframes in the decoder. The values then persist from the previous frame unless an update bit is set in the bitstream. This data is not included in the entropy data saved by the 'refresh entropy' bit in the bitstream, so it is effectively an additional contextual element beyond the 3 ref-frames and the entropy data. The encoder was treating this delta update bit as update-if-nonzero, meaning that the value would be refreshed even if it hadn't changed, and more significantly, if the correct value for the delta changed to zero, the update wouldn't be sent, and the decoder would preserve the last (presumably non-zero) value. This patch updates the encoder to send an update only if the value has changed from the previously transmitted value. It also forces the value to be transmitted in error resilient mode, to account for lost context in the event of lost frames. Change-Id: I56671d5b42965d0166ac226765dbfce3e5301868

Improve MV prediction accuracy to achieve performance gain Add vp8_mv_pred() to better predict starting MV for NEWMV mode in vp8_rd_pick_inter_mode(). Set different search ranges according to MV prediction accuracy, which improves encoder performance without hurting the quality. Also, as Yaowu suggested, using diamond search result as full search starting point and therefore adjusting(reducing) full search range helps the performance.

Reduced the size of MB_MODE_INFO Moved partition_bmi and partition_count out of MB_MODE_INFO and placed into MACROBLOCK. Also reduced the size of other members of the MB_MODE_INFO struct. For 1080p, the memory was reduced by 1,209,516 bytes. The decoder performance appeared to improve by 3% for the clip used. Note: The main goal for this change is to improve the decoder performance. The encoder will be revisited at a later date for further structure cleanup. Change-Id: I4733621292ee9cc3fffa4046cb3fd4d99bd14613

quantizer: fix assertion in fast quantizer path The fast quantizer assembly code has not been updated to match the new exact quantizer, which was made the default in commit 6adbe09. Specifically, they are not aware of the potential for the coefficient to be scaled, which results in the quantized result exceeding the range of the DCT. This patch restores the previous behavior of using the non-shifted coefficients when in the fast quantizer code path, but unfortunately requires rebuilding the tables when switching between the two.

Changed segmentation check order In SPLITMV, the 8x8 segment will be checked first. If the 8x8 rd is better than the best, we check the other segments. Otherwise bail. Adjustments to the thresh_mult were necessary to make up for the initial quality loss. The performance improved by 20% (average) for good quality, speed 0 and speed 1, while the overall quality remained the same. Change-Id: I717aef401323c8a254fba3e9777d2a316c774cc3

Replaced recode loop test with a function call Replaced existing code to decide if a frame recode is required with a function call. This is to simplify addition of extra clauses that may be needed for the planned constrained quality mode. Also fixed a bug where by alt ref not considered in the test.

quantizer: fix assertion in fast quantizer path The fast quantizer assembly code has not been updated to match the new exact quantizer, which was made the default in commit 6adbe09. Specifically, they are not aware of the potential for the coefficient to be scaled, which results in the quantized result exceeding the range of the DCT. This patch restores the previous behavior of using the non-shifted coefficients when in the fast quantizer code path, but unfortunately requires rebuilding the tables when switching between the two.

change to make use of more trellis quantization when a subsequent frame is encoded as an alt reference frame, it is unlikely that any mb in current frame will be used as reference for future frames, so we can enable quantization optimization even when the RD constant is slightly rate-biased. The change has an overall benefit between 0.1% to 0.2% bit savings on the test sets based on vpxssim scores. Change-Id: I9aa7bc5cd573ea84e3ee655d2834c18c4460ceea

Reduced the size of MB_MODE_INFO Moved partition_bmi and partition_count out of MB_MODE_INFO and placed into MACROBLOCK. Also reduced the size of other members of the MB_MODE_INFO struct. For 1080p, the memory was reduced by 1,209,516 bytes. The decoder performance appeared to improve by 3% for the clip used. Note: The main goal for this change is to improve the decoder performance.

Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise. I have not attempted to make any changes to configure to do this automatically. Doing so will probably require the addition of new configure options. Many of the hooks for RTCD on ARM were already there, but a lot of the code had bit-rotted, and a good deal of the ARM-specific code is not integrated into the RTCD structs at all. I did not try to resolve the latter, merely to add the minimal amount of protection around them to allow RTCD to work. Those functions that were called based on an ifdef at the calling site were expanded to check the RTCD flags at that site, but they should be added to an RTCD struct somewhere in the future. The functions invoked with global function pointers still are, but these should be moved into an RTCD struct for thread safety (I believe every platform currently supported has atomic pointer stores, but this is not guaranteed). The encoder's boolhuff functions did not even have _c and armv7 suffixes, and the correct version was resolved at link time. The token packing functions did have appropriate suffixes, but the version was selected with a define, with no associated RTCD struct. However, for both of these, the only armv7 instruction they actually used was rbit, and this was completely superfluous, so I reworked them to avoid it. The only non-ARMv4 instruction remaining in them is clz, which is ARMv5 (not even ARMv5TE is required). Considering that there are no ARM-specific configs which are not at least ARMv5TE, I did not try to detect these at runtime, and simply enable them for ARMv5 and above. Finally, the NEON register saving code was completely non-reentrant, since it saved the registers to a global, static variable. I moved the storage for this onto the stack. A single binary built with this code was tested on an ARM11 (ARMv6) and a Cortex A8 (ARMv7 w/NEON), for both the encoder and decoder, and produced identical output, while using the correct accelerated functions on each. I did not test on any earlier processors. Change-Id: I45cbd63a614f4554c3b325c45d46c0806f009eaa

Improve MV prediction accuracy to achieve performance gain Add vp8_mv_pred() to better predict starting MV for NEWMV mode in vp8_rd_pick_inter_mode(). Set different search ranges according to MV prediction accuracy, which improves encoder performance without hurting the quality. Also, as Yaowu suggested, using diamond search result as full search starting point and therefore adjusting(reducing) full search range helps the performance.

Add simple version of activity masking. This uses MB variance to change the RDO weight for mode decision and quantization. Activity is normalized against the average for the frame, which is currently tracked using feed-forward statistics. This could also be used to adjust the quantizer for the entire frame, but that requires more extensive rate control changes. This does not yet attempt to adapt the quantizer within the frame, but the signaling cost means that will likely only be useful at very high rates.

Move firstpass motion map to stats packet The first implementation of the firstpass motion map for motion compensated temporal filtering created a file, fpmotionmap.stt, in the current working directory.

Add half-pixel variance RTCD functions NEON has optimized 16x16 half-pixel variance functions, but they were not part of the RTCD framework. Add these functions to RTCD, so that other platforms can make use of this optimization in the future and special-case ARM code can be removed. A number of functions were taking two variance functions as parameters. These functions were changed to take a single parameter, a pointer to a struct containing all the variance functions for that block size. This provides additional flexibility for calling additional variance functions (the half-pixel special case, for example) and by initializing the table for all block sizes, we don't have to construct this function pointer table for each macroblock.

#if HAVE_ARMV7
Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise. I have not attempted to make any changes to configure to do this automatically. Doing so will probably require the addition of new configure options. Many of the hooks for RTCD on ARM were already there, but a lot of the code had bit-rotted, and a good deal of the ARM-specific code is not integrated into the RTCD structs at all. I did not try to resolve the latter, merely to add the minimal amount of protection around them to allow RTCD to work. Those functions that were called based on an ifdef at the calling site were expanded to check the RTCD flags at that site, but they should be added to an RTCD struct somewhere in the future. The functions invoked with global function pointers still are, but these should be moved into an RTCD struct for thread safety (I believe every platform currently supported has atomic pointer stores, but this is not guaranteed). The encoder's boolhuff functions did not even have _c and armv7 suffixes, and the correct version was resolved at link time. The token packing functions did have appropriate suffixes, but the version was selected with a define, with no associated RTCD struct. However, for both of these, the only armv7 instruction they actually used was rbit, and this was completely superfluous, so I reworked them to avoid it. The only non-ARMv4 instruction remaining in them is clz, which is ARMv5 (not even ARMv5TE is required). Considering that there are no ARM-specific configs which are not at least ARMv5TE, I did not try to detect these at runtime, and simply enable them for ARMv5 and above. Finally, the NEON register saving code was completely non-reentrant, since it saved the registers to a global, static variable. I moved the storage for this onto the stack. A single binary built with this code was tested on an ARM11 (ARMv6) and a Cortex A8 (ARMv7 w/NEON), for both the encoder and decoder, and produced identical output, while using the correct accelerated functions on each. I did not test on any earlier processors. Change-Id: I45cbd63a614f4554c3b325c45d46c0806f009eaa

Tuning for the more exact quantizer. Small changes to the default zero bin and rounding tables.

Fix loopfilter delta zero transitions Loopfilter deltas are initialized to zero on keyframes in the decoder. The values then persist from the previous frame unless an update bit is set in the bitstream. This data is not included in the entropy data saved by the 'refresh entropy' bit in the bitstream, so it is effectively an additional contextual element beyond the 3 ref-frames and the entropy data. The encoder was treating this delta update bit as update-if-nonzero, meaning that the value would be refreshed even if it hadn't changed, and more significantly, if the correct value for the delta changed to zero, the update wouldn't be sent, and the decoder would preserve the last (presumably non-zero) value. This patch updates the encoder to send an update only if the value has changed from the previously transmitted value. It also forces the value to be transmitted in error resilient mode, to account for lost context in the event of lost frames. Change-Id: I56671d5b42965d0166ac226765dbfce3e5301868

Fix loopfilter delta zero transitions Loopfilter deltas are initialized to zero on keyframes in the decoder. The values then persist from the previous frame unless an update bit is set in the bitstream. This data is not included in the entropy data saved by the 'refresh entropy' bit in the bitstream, so it is effectively an additional contextual element beyond the 3 ref-frames and the entropy data. The encoder was treating this delta update bit as update-if-nonzero, meaning that the value would be refreshed even if it hadn't changed, and more significantly, if the correct value for the delta changed to zero, the update wouldn't be sent, and the decoder would preserve the last (presumably non-zero) value. This patch updates the encoder to send an update only if the value has changed from the previously transmitted value. It also forces the value to be transmitted in error resilient mode, to account for lost context in the event of lost frames. Change-Id: I56671d5b42965d0166ac226765dbfce3e5301868

Fix a bug in motion search code The MV's range is 256. Since the new motion search uses a different starting MV than the center ref MV, a MV range checking needs to be done to avoid corruption. Change-Id: I8ae0721d1bd203639e13891e2e54a2e87276f306

Improve MV prediction accuracy to achieve performance gain Add vp8_mv_pred() to better predict starting MV for NEWMV mode in vp8_rd_pick_inter_mode(). Set different search ranges according to MV prediction accuracy, which improves encoder performance without hurting the quality. Also, as Yaowu suggested, using diamond search result as full search starting point and therefore adjusting(reducing) full search range helps the performance.

Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise.

Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run.

#if HAVE_ARMV7
Add runtime CPU detection support for ARM. The primary goal is to allow a binary to be built which supports NEON, but can fall back to non-NEON routines, since some Android devices do not have NEON, even if they are otherwise ARMv7 (e.g., Tegra). The configure-generated flags HAVE_ARMV7, etc., are used to decide which versions of each function to build, and when CONFIG_RUNTIME_CPU_DETECT is enabled, the correct version is chosen at run time. In order for this to work, the CFLAGS must be set to something appropriate (e.g., without -mfpu=neon for ARMv7, and with appropriate -march and -mcpu for even earlier configurations), or the native C code will not be able to run. The ASFLAGS must remain set for the most advanced instruction set required at build time, since the ARM assembler will refuse to emit them otherwise. I have not attempted to make any changes to configure to do this automatically. Doing so will probably require the addition of new configure options. Many of the hooks for RTCD on ARM were already there, but a lot of the code had bit-rotted, and a good deal of the ARM-specific code is not integrated into the RTCD structs at all. I did not try to resolve the latter, merely to add the minimal amount of protection around them to allow RTCD to work. Those functions that were called based on an ifdef at the calling site were expanded to check the RTCD flags at that site, but they should be added to an RTCD struct somewhere in the future. The functions invoked with global function pointers still are, but these should be moved into an RTCD struct for thread safety (I believe every platform currently supported has atomic pointer stores, but this is not guaranteed). The encoder's boolhuff functions did not even have _c and armv7 suffixes, and the correct version was resolved at link time. The token packing functions did have appropriate suffixes, but the version was selected with a define, with no associated RTCD struct. However, for both of these, the only armv7 instruction they actually used was rbit, and this was completely superfluous, so I reworked them to avoid it. The only non-ARMv4 instruction remaining in them is clz, which is ARMv5 (not even ARMv5TE is required). Considering that there are no ARM-specific configs which are not at least ARMv5TE, I did not try to detect these at runtime, and simply enable them for ARMv5 and above. Finally, the NEON register saving code was completely non-reentrant, since it saved the registers to a global, static variable. I moved the storage for this onto the stack. A single binary built with this code was tested on an ARM11 (ARMv6) and a Cortex A8 (ARMv7 w/NEON), for both the encoder and decoder, and produced identical output, while using the correct accelerated functions on each. I did not test on any earlier processors. Change-Id: I45cbd63a614f4554c3b325c45d46c0806f009eaa

improve average framerate calculation Change Ice204e86 identified a problem with bitrate undershoot due to low precision in the timestamps passed to the library. This patch takes a different approach by calculating the duration of this frame and passing it to the library, rather than using a fixed duration and letting the library average it out with higher precision timestamps. This part of the fix only applies to vpxenc. This patch also attempts to fix the problem for generic applications that may have made the same mistake vpxenc did. Instead of calculating this frame's duration by the difference of this frame's and the last frame's start time, we use the end times instead. This allows the framerate calculation to scavenge "unclaimed" time from the last frame. For instance: start | end | calculated duration ======+=======+==================== 0ms 33ms 33ms 33ms 66ms 33ms 66ms 99ms 33ms 100ms 133ms 34ms Change-Id: I92be4b3518e0bd530e97f90e69e75330a4c413fc
