+Welcome to read this page!
+
+How to run renderscript in VP9 decode
+
+  1. Compile RenderScript Kernel(We use zero copy this version,
+                                 if ndk rs module don't support this,
+                                 it can't pass compile)
+  Because RenderScript need g++, but VP9 use gcc.
+  So we need to compile rs alone as a so library. Then VP9 project load/use it.
+  RS code is in vp9/common/kernel/rs/, there is a compile.sh in that folder,
+  We can use sh to compile rs kernel.(need NDK-r9b or higher, we need to config ndk in path).
+  If compile success, it will gen:
+  vp9_rs_packing.so(vp9/common/kernel/rs/)
+  librs.inter_rs.so(vp9/common/kernel/rs/obj/)
+  libstlport_shared.so(vp9/common/kernel/rs/obj/)
+
+  2. Compile VP9 project
+  Just Compile it normally.
+
+  3. Run vpxdec with RenderScript(We use zero copy this version,
+                                  if system RS module don't support this,
+                                  it won't work)
+  [1]: push vp9_rs_packing.so to /data/local/tmp/(or /vendor/lib, /system/lib,
+       need adb remount)
+  [2]: push librs.inter_rs.so to /data/local/tmp/(or /vendor/lib, /system/lib,
+       need adb remount)
+  [3]: push libstlport_shared.so to /data/local/tmp/(or /vendor/lib, /system/lib,
+       need adb remount)
+  [4]: push vpxdec to /data/local/tmp
+  [5]: adb shell          (as root)
+  [6]: cd /data/local/tmp (on device)
+  [7]: export RSENABLE=1  (on device, if not, it won't use RS)
+  [8]: export QCTENABLE=1 (on device, enable qct kernel)
+  [9]: export OPENABLE=1  (on device, enable optimized kernel, dependence on system and driver)
+  [10]:export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/local/tmp (on device,
+       if we push .so file to /data/local/tmp, we need set this)
+  [11]:run vpxdec normally(on device)

+// Decode With Partial Drops Example
+// =========================
+//
+// This is an example utility which drops a series of frames (or parts of
+// frames), as specified on the command line. This is useful for observing the
+// error recovery features of the codec.
+//
+// Usage
+// -----
+// This example adds a single argument to the `simple_decoder` example,
+// which specifies the range or pattern of frames to drop. The parameter is
+// parsed as follows.
+//
+// Dropping A Range Of Frames
+// --------------------------
+// To drop a range of frames, specify the starting frame and the ending
+// frame to drop, separated by a dash. The following command will drop
+// frames 5 through 10 (base 1).
+//
+//  $ ./decode_with_partial_drops in.ivf out.i420 5-10
+//
+//
+// Dropping A Pattern Of Frames
+// ----------------------------
+// To drop a pattern of frames, specify the number of frames to drop and
+// the number of frames after which to repeat the pattern, separated by
+// a forward-slash. The following command will drop 3 of 7 frames.
+// Specifically, it will decode 4 frames, then drop 3 frames, and then
+// repeat.
+//
+//  $ ./decode_with_partial_drops in.ivf out.i420 3/7
+//
+// Dropping Random Parts Of Frames
+// -------------------------------
+// A third argument tuple is available to split the frame into 1500 bytes pieces
+// and randomly drop pieces rather than frames. The frame will be split at
+// partition boundaries where possible. The following example will seed the RNG
+// with the seed 123 and drop approximately 5% of the pieces. Pieces which
+// are depending on an already dropped piece will also be dropped.
+//
+//  $ ./decode_with_partial_drops in.ivf out.i420 5,123
+//
+// Extra Variables
+// ---------------
+// This example maintains the pattern passed on the command line in the
+// `n`, `m`, and `is_range` variables:
+//
+// Making The Drop Decision
+// ------------------------
+// The example decides whether to drop the frame based on the current
+// frame number, immediately before decoding the frame.

+// Configuration
+// -------------
+// Keyframes can be forced by setting the VPX_EFLAG_FORCE_KF bit of the
+// flags passed to `vpx_codec_control()`. In this example, we force a
+// keyframe every 8 frames.
+//
+// Observing The Effects
+// ---------------------
+// The output of the encoder examples shows a 'K' rather than a dot '.'
+// when the encoder generates a keyframe. Note that every 8 frames a 'K'
+// is output.

-// VP8 Set Active and ROI Maps
-// ===========================
-//
-// This is an example demonstrating how to control the VP8 encoder's
-// ROI and Active maps.
-//
-// ROI (Reigon of Interest) maps are a way for the application to assign
-// each macroblock in the image to a region, and then set quantizer and
-// filtering parameters on that image.
-//
-// Active maps are a way for the application to specify on a
-// macroblock-by-macroblock basis whether there is any activity in that
-// macroblock.
-//
-//
-// Configuration
-// -------------
-// An ROI map is set on frame 22. If the width of the image in macroblocks
-// is evenly divisble by 4, then the output will appear to have distinct
-// columns, where the quantizer, loopfilter, and static threshold differ
-// from column to column.
-//
-// An active map is set on frame 33. If the width of the image in macroblocks
-// is evenly divisble by 4, then the output will appear to have distinct
-// columns, where one column will have motion and the next will not.
-//
-// The active map is cleared on frame 44.
-//
-// Observing The Effects
-// ---------------------
-// Use the `simple_decoder` example to decode this sample, and observe
-// the change in the image at frames 22, 33, and 44.

+// macroblock-by-macroblock basis whether there is any activity in that
+// macroblock.
+//
+//
+// Configuration
+// -------------
+// An ROI map is set on frame 22. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where the quantizer, loopfilter, and static threshold differ
+// from column to column.
+//
+// An active map is set on frame 33. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where one column will have motion and the next will not.
+//
+// The active map is cleared on frame 44.
+//
+// Observing The Effects
+// ---------------------
+// Use the `simple_decoder` example to decode this sample, and observe
+// the change in the image at frames 22, 33, and 44.

+- Test (and fix, if necessary) support for unknown sizes.
+- Test (and fix, if necessary) support for large files.
+- Read past unknown elements rather than seeking.
+- Try to handle unknown elements with unknown sizes.
+- Formalize handling of default element values.
+- Try to resynchronize stream when read_block fails so that failure to parse
+  a single block can be treated as non-fatal.
+- Make logging more useful to API users.
+- Avoid reparsing Cues and ignore any SeekHead at end of file.
+- Optionally build a Cue index as Clusters are parsed.
+- Support seeking without Cues.
+- Avoid building a list of Clusters as they are parsed and retain only the
+  last one parsed.
+- Add an asynchronous error code to struct nestegg and ensure that API calls
+  continue to fail safely one a fatal error has been returned.
+- Modify parser/data structures to provide a clean separation.  Perhaps the
+  parser should return a generic tree of nodes that a second pass uses to
+  initialize the main data structures.
+- Use pool allocator for all allocations.

+halloc 1.2.1
+============
+      
+	Hierarchical memory heap interface - an extension to standard
+	malloc/free interface that simplifies tasks of memory disposal 
+	when allocated structures exhibit hierarchical properties.
+
+	http://swapped.cc/halloc
+=
+	To build libhalloc.a with GNU tools run
+		make
+
+	To install in /usr/include and /usr/lib
+		make install
+
+	To cleanup the build files 
+		make clean
+=
+	halloc-1.2.1
+		* fixed a double-free bug in _set_allocator() as per
+		  Matthew Gregan comments
+
+		* switched to using NULL instead of 0 where applicable
+
+	halloc-1.2.0
+		* added missing <string.h> include to halloc.c
+		
+		* improved standard compliance thanks to the feedback
+		  received from Stan Tobias. Two things were fixed -
+		  
+		- hblock_t structure no longer uses zero-sized 'data'
+		  array, which happened to be common, but non-standard
+		  extension; 
+		  
+		- secondly, added the code to test the behaviour of 
+		  realloc(ptr, 0). Standard allows it NOT to act as
+		  free(), in which case halloc will use its own version
+		  of allocator calling free() when neccessary.
+
+	halloc-1.1.0
+		* initial public release (rewrite of hhmalloc library)

+dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+dnl
+dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
+dnl existence of an include file <stdint.h> that defines a set of
+dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
+dnl installations will not provide this file, but some will have the
+dnl very same definitions in <inttypes.h>. In other enviroments we can
+dnl use the inet-types in <sys/types.h> which would define the typedefs
+dnl int8_t and u_int8_t respectivly.
+dnl
+dnl This macros will create a local "_stdint.h" or the headerfile given
+dnl as an argument. In many cases that file will just "#include
+dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
+dnl it will provide the set of basic 'stdint's definitions/typedefs:
+dnl
+dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+dnl   int_least32_t.. int_fast32_t.. intmax_t
+dnl
+dnl which may or may not rely on the definitions of other files, or
+dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
+dnl type.
+dnl
+dnl if your header files require the stdint-types you will want to
+dnl create an installable file mylib-int.h that all your other
+dnl installable header may include. So if you have a library package
+dnl named "mylib", just use
+dnl
+dnl      AX_CREATE_STDINT_H(mylib-int.h)
+dnl
+dnl in configure.ac and go to install that very header file in
+dnl Makefile.am along with the other headers (mylib.h) - and the
+dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
+dnl obtain the stdint-types.
+dnl
+dnl Remember, if the system already had a valid <stdint.h>, the
+dnl generated file will include it directly. No need for fuzzy
+dnl HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled
+dnl its stdint.h for non-c99 compilation and the c99-mode is not the
+dnl default. Therefore this macro will not use the compiler's stdint.h
+dnl - please complain to the GCC developers).
