Author: Janne Grunau <[email protected]> Committer: Janne Grunau <[email protected]> Date: Tue Dec 18 22:57:58 2012 +0100 mpegvideo: increase edge_emu_buffer size for VC1 The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before f1d8763a02b5fce since the size for edge_emu_buffer was always calculated with 2 byte per pixel since the linesize was not known. Fixes occasionally fate errors in vc1_sa10143. --- libavcodec/mpegvideo.c | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/libavcodec/mpegvideo.c b/libavcodec/mpegvideo.c index 8cd8df8..edd5253 100644 --- a/libavcodec/mpegvideo.c +++ b/libavcodec/mpegvideo.c @@ -241,8 +241,10 @@ int ff_mpv_frame_size_alloc(MpegEncContext *s, int linesize) // edge emu needs blocksize + filter length - 1 // (= 17x17 for halfpel / 21x21 for h264) + // VC1 computes luma and chroma simultaneously and needs 19X19 + 9x9 + // at uvlinesize.
