Andriy Gelman	5282db5929	avcodec/mpeg: Initialize quarter_sample parameter from previous thread. Fixes #7410. The value of sub-pixel precision for me/mc can change during an Intra frame. In multi-threaded decoding this change is not propagated to other frame threads causing decoding artifacts. This patch initializes the sub-pixel precision parameter from previous thread, which fixes the issue. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	6 years ago

Paul B Mahol	faca28c264	avcodec: rewrite gif muxing and encoding Now "-c copy" works. Update FATE files. Demuxer only split file into packets, no data is trimmed. Encoder & muxer currently expect completely another format where muxer writes stuff like disposal method which should be really encoder job. With this patch muxer only modifies delay between two packets. Codec copy need to have same behavior between demuxer and muxer to work correctly. Fixes #6640.	6 years ago

Carl Eugen Hoyos	32601fb821	lavfi/signalstats: Cast the return value of AV_RN16() to int. It is unsigned at least on arm, fixes the following warnings: libavfilter/vf_signalstats.c:833:21: warning: taking the absolute value of unsigned type 'unsigned int' has no effect dify += abs(yuv - AV_RN16(prev->data[0] + pw + i * 2));	6 years ago
Rostislav Pehlivanov	83db1efd42	opusenc: fix infinite loop if flushing encoder upon init The issue is that the afq still has samples as on init it counts the overlap used as a delay to adjust the PTS it generates, hence we can't rely on it right after init. So just check to see if any frames have been encoded. frame_number can't be anything but 0 right after init and can only be set by lavc.
