Currently internal, but perhaps interesting to expose, is the error_resilience statistics for H264/MPEG*. Blockiness can actually be measured objectively, I'm not immediately aware of an opensource project doing that or containing code for that, but either way you can do that outside Libav/FFmpeg per se. (I don't know enough about audio, sorry.) Ronald _______________________________________________ libav-tools mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-tools
