It works if I use source material that has 44.1 kHz or if I do at the first place $ ffmpeg -i input.foo -strict -2 -acodec dts -ar 44100 -f spdif foo.spdif I'm not sure if there is a change in pitch, it sounds a bit more dull, so maybe there is.

Do you know if ffmpeg DTS encoder quality will be improved? Am 17.08.16 um 07:05 schrieb Carl Eugen Hoyos: > How can I reproduce this? Do the following: 1. Find any source material with 48 kHz sampling rate (mine was alac/flac, but don't think this matters). 2. Open this file in VLC, check that it plays nicely and note the duration 3. Do $ ffmpeg -i /test.flac -strict -2 -acodec dts -f spdif /test.spdif 4. Than do $ ffmpeg -f s16le -ac 2 -ar 44100 -i /test.spdif -acodec copy /test.wav 5. Open WAV file in VLC (I had to use --demux=ffmpeg to open it in VLC) 6. Play the file and note the longer duration and that file sounds slower _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
