The previous version 2 patches were deprecated for using pointer to itself can be unsafe when release frames.
This patch set is mainly about avoiding using memcpy when fetching frame data, and fixed missing start codes which may cause error packetization sometime. Default info level of libdavs2 was changed because we found debug info is useless in most of the time. hwrenx (3): lavc/avs2_parser.c: fix for missing start code lavc/libdavs2.c: change decoder info level lavc/libdavs2.c: use decoder data directly instead of memcpy libavcodec/avs2_parser.c | 4 +++- libavcodec/libdavs2.c | 58 ++++++++++++++++++++++++++++-------------------- 2 files changed, 37 insertions(+), 25 deletions(-) The performance comparison is like following: [Platform] Intel® Core™ i7-8700k CPU @ 3.70GHz × 6 / 16GiB [Command] ffmpeg -i test.avs2 -vsync 0 -f null - [Stream] 7680x4320 yuv420p Random Access [Original version] frame= 2669 fps= 23 q=-0.0 Lsize=N/A time=00:00:53.44 bitrate=N/A speed=0.465x [Optimized version] frame= 2669 fps= 42 q=-0.0 Lsize=N/A time=00:00:53.44 bitrate=N/A speed=0.836x -- 2.7.4 _______________________________________________ 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".
