Mans Rullgard	ac08f798bb	mp3dec: hack: fix decoding with safe bitstream reader The buffer splicing relies on the bitstream reader over-reading the end of the buffer as declared in init_get_bits(), although more data is actually present.

Ronald S. Bultje	8cfbbd928c	get_bits: introduce safe bitreading to prevent overreads. When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate files. Other codecs are affected to a lesser extent because they are less optimized; e.g., VC-1 slows down by less than 1% (all on x86). The patch generated 3 extra instructions (cmp, cmovae and mov) per call to get_bits(). The performance penalty on ARM is within the error margin for most files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264. Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.	2011-12-17 14:03:41 +00:00
Mans Rullgard	a1e98f198e	get_bits: remove A32 variant The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>	2011-12-16 21:21:48 +00:00

Sjoerd Simons	f32fd31858	g722: Change bits per sample to 4 Earlier, bits per sample was defined as 8, since bits_per_coded_sample was used to indicate whether to ignore the lower bits of the codeword, having values 6, 7 or 8. g722 encodes 2 samples into one byte codeword, therefore the bits per sample is 4. By changing this, the generated timestamps for streams encoded with g722 become correct. This makes timestamp generation for g722 data correct (both when encoding and when demuxing from raw g722 files). Signed-off-by: Martin Storsjö <martin@martin.st>	2011-12-05 12:41:46 +02:00
Martin Storsjö	6fcbb0f553	g722dec: Signal skipping the lower bits via AVOptions instead of bits_per_coded_sample This avoids using bits_per_coded_sample for this information. bits_per_coded_sample should be 4 for this codec normally, since two samples are encoded into one 8 bit codeword. In principle, this might be info that needs to be passed from a demuxer, and in that case, a private AVOption isn't the best choice, but no such samples are available at the moment, so that use case is purely theoretical at the moment.

Janne Grunau	0945eddec0	pthread: do not touch has_b_frames Adding the thread count in frame level multithreading to has_b_frames as an additional delay causes more problems than it solves. For example inconsistent behaviour during timestamp calculation in libavformat. Thread count and frame level multithreading are both set by the user. If the additional delay caused by frame level multithreading needs to be considered in the calling code it has all information to take it into account. Should it become necessary to calculate a maximum delay inside libavcodec it should be exported as its own field and not reusing an existing field. Based on a patch by Michael Niedermayer.

Martin Storsjö	1b6da627d4	avcodec: Remove a misplaced and useless attribute_deprecated If attribute_deprecated is used in an enum declaration, it should follow the 'enum' keyword, otherwise it's ignored silently. This is the only case of attribute_deprecated for enum declarations currently. Currently, this attribute_deprecated doesn't have any effect. If moved to the right place, it emits a warning every single time avcodec.h is included, like this: avcodec.h:2827: warning: ‘AVLPCType’ is deprecated (declared at avcodec.h:543) There is already a working attribute_deprecated for the corresponding field in AVCodecContext, so therefore this one shouldn't be needed.

Justin Ruggles	6ac34eed54	g726: use bits_per_coded_sample instead of bitrate to determine mode This requires some workarounds in the WAV muxer and demuxer. We need to write the correct bits_per_coded_sample and block_align in the muxer. In the demuxer, we cannot rely on the bits_per_coded_sample value, so we use the bit rate and sample rate to determine the value. This avoids having the decoder rely on AVCodecContext.bit_rate, which is not required to be set by the user for decoding according to our API.	2011-11-01 21:23:03 -04:00

Justin Ruggles	0093f96d34	pcmdec: return buf_size instead of src-buf. The values will always be the same, so this change eliminates an unneeded variable. It also gets rid of the need to reset src when memcpy() is used.	2011-10-26 12:01:07 -04:00
Justin Ruggles	85579b6381	avcodec: remove the Zork PCM encoder. The Zork PCM decoder does not decode the 1 sample we have correctly, therefore the encoder based on the decoder is also incorrect. There is no good reason to keep the encoder.	2011-10-26 12:01:07 -04:00

Justin Ruggles	d251c85dce	alacdec: cosmetics: rename 'wasted_bits' to 'extra_bits'. The bits are not wasted, they are additional low bits that are added to the 16-bit decompressed samples to increase the output sample depth.	2011-10-26 11:50:16 -04:00

Janne Grunau	cd8c64e197	Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context" This reverts commit `da22ba7df4` since it broke slice threading.
