The filter does not yet work for 96/24 while -core_only works fine, you can (for example) test with the following lines (using the file you found): $ ffmpeg -i sample.dts -f crc - $ ffmpeg -core_only 1 -i sample.dts -f crc - $ ffmpeg -i sample.dts -acodec copy -bsf:a dca_core out.dts $ md5sum out.dts sample.dts Carl Eugen _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
