This patch series gathers all changes affecting the cached reader and the file get_bits.h. The largest consists in modifying the cached reader so that the cache can be selected to be (native) 32 bits large. Then, due to some corner cases from various codecs, reducing some reads or fixing functions that can not guarantee the usual number of bits, are needed.
Note: the MVHA sample was generated using the pattern generation from VirtualDub2 (Tools->Create test video->zone plates) and the MVHA codec, and is 235186 bytes. Christophe Gisquet (7): fate: add a MVHA test get_bits: support 32bits cache get_xbits: request fewer bits get_bits: replace index by an incremented pointer get_bits: improve and fix get_bits_long for 32b get_bits: change refill to RAD pattern get_bits: use immediate in skip_remaining libavcodec/get_bits.h | 193 +++++++++++++++++++++++++++------------- libavcodec/mvha.c | 2 +- libavcodec/utvideodec.c | 2 +- tests/fate/video.mak | 3 + tests/ref/fate/mvha | 6 ++ 5 files changed, 143 insertions(+), 63 deletions(-) create mode 100644 tests/ref/fate/mvha -- 2.26.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
