[FFmpeg-devel] [PATCH] avcodec/svq1: fix interframe mean VLC symbols

Fixes ticket #128. The SVQ1 interframe mean VLC symbols -128 and 128 are incorrectly swapped in our SVQ1 implementation, resulting in visible artifacts for some videos. This patch unswaps the order of these two symbols. The most noticable example of the artiacts caused by this error can be observ

[FFmpeg-devel] [PATCH 6/6] avcodec/mpv_reconstruct_mb_template: Optimize dead code away

[FFmpeg-devel] [PATCH 4/6] avcodec/mpegvideo: Split ff_mpv_reconstruct_mb() into de/encoder part

This has the advantage of not having to check for whether a given MpegEncContext is actually a decoder or an encoder context at runtime. To do so, mpv_reconstruct_mb_internal() is moved into a new template file that is included by both mpegvideo_enc.c and mpegvideo_dec.c; the decoder-only code (ma

[FFmpeg-devel] [PATCH 3/6] avcodec/mpegvideo: Inline is_encoder in mpv_reconstruct_mb_internal()

Up until now, we inlined lowres_flag as well as is_mpeg12 independently (unless CONFIG_SMALL was true); this commit changes this to instead inline mpv_reconstruct_mb_internal() (at most) four times, namely once for encoders, once for decoders using lowres and once for non-lowres mpeg-1/2 decoders a

[FFmpeg-devel] [PATCH 2/6] avcodec/mpegvideo: Make inlining is_mpeg12 more flexible

There are two types of checks for whether the current codec is MPEG-1/2 in mpv_reconstruct_mb_internal(): Those that are required for correctness and those that are not; an example of the latter is "is_mpeg12 || (s->codec_id != AV_CODEC_ID_WMV2)". The reason for the existence of such checks is that

Both the FFV1 decoder and encoder use a template of their own to generate code multiple times. They also use a common template, used by both decoder and encoder templates which is currently instantiated in ffv1.h (and therefore also in ffv1.c, which doesn't need it at all). All these templates hav
