Pascal Patry <[EMAIL PROTECTED]> added the comment: I can confirm that both put_h264_chroma_mc4_mmx and put_h264_chroma_mc4_ssse3 are able to trigger an invalid read.
This file reproduce the problem at 3:02. http://movies.apple.com/movies/sony_pictures/hancock/hancock-tlr2r_h480p.mov When the invalid read happen, the chroma function is reading from the last stride of the src buffer. This workaround in "libavcodec/utils.c" will avoid the problem: - buf->base[i]= av_malloc(size[i]+16); //FIXME 16 + buf->base[i]= av_malloc(size[i]+16+656); //FIXME 16 ______________________________________________________ FFmpeg issue tracker <[EMAIL PROTECTED]> <https://roundup.mplayerhq.hu/roundup/ffmpeg/issue327> ______________________________________________________
