I investigated "skipping problem" a little further, and it doesn't
seem to happen with two-channel output (at least I couldn't make it
happen). It does happen with "-channels 6" though. So then I thought,
maybe it's a problem with the channel reordering and tried "-channels
4", where we don't reorder. But it also happens there. Weird. Then
sometimes it doesn't happen at all.
It doesn't only happen after 30 seconds either, it happens EVERY 30
seconds. Maybe some data type is too small or something?
Verbose output doesn't show any errors, but still something weird
happens. Usually the output looks like this (mp3 playback):
