I guess this is for the postprocessing comparison document, right? It is important you use low-quality content (e.g. matrix_bench.mpg encoded to 200Kbits/s) or you can use the reference images here: http://www.compression.ru/video/deblocking/index_en.html [...] -- FFmpeg = Faithful and Freak Magnificient Philosophical Elastic Game _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
