Samples for that are available in the usual places, ie this one should do the trick: http://samples.ffmpeg.org/A-codecs/DTS/dts/Master%20Audio%207.1%2024bit.dts I also used to have a sample somewhere where all audible audio is in the lossless extension for all channels, playing just the core yielded nothing but silence. Maybe I can dig it up if its of interest. - Hendrik _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
