thanks for the explanation. I don't think that I have an ipod around here to test, but this is indeed an indication for an faulty alac encoder.
Next steps: we need to know if this still happens with ffmpeg trunk's alac encoder and if yes, then forward this upstream. Just to be sure, can you please share your ffmpeg command line that you used to create mono alac files? -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4 -- ffmpeg generates mono ALAC .m4a sound files which play double speed https://bugs.launchpad.net/bugs/661922 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
