Hi Derek, Indeed it is a bug and that is the correct fix. The function ff_init_slice_from_src is used for initializing the source data but as it is always 'relative' it starts at 0. It is also used to initialize the destination slice but my guess is that usually the destination stride is equal, and thus it went unnoticed.
Do you have a sample which make this bug evident? I think the new slice code is enabled by default since the end of last year's GSoC. If you find any bug or have questions about the new swscale slice code, feel free to contact me. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
