It's can be a big deal for hardware decoding, because hw surfaces might be a more constrained resource than system RAM. Also, you often have to preallocate _all_ surfaces you're going to use, so you'll have to add the exact number of additionally needed surfaces to the preallocation. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
