[FFmpeg-devel] [PATCH] avcodec/utils: do not reallocate packet buffer for AV_CODEC_ID_WRAPPED_AVFRAME

2017-02-18 Thread Marton Balint
Reallocating a wrapped avframe invalidates internal pointers, such as extended data. FFmpeg has another way of passing AVFrames to muxers, but it seems the API (av_write_uncoded_frame) is not implemented in the ffmpeg CLI yet. Signed-off-by: Marton Balint --- libavcodec/utils.c | 4 ++-- 1 file

[FFmpeg-devel] [PATCH] speedhq: fix decoding artifacts

2017-02-18 Thread Steinar H. Gunderson
The quantization table is stored in the natural order, but when we access it, we use an index that's in zigzag order, causing us to read the wrong value. This causes artifacts, especially in areas with horizontal or vertical edges. The artifacts look a lot like the DCT ringing artifacts you'd expec
