Comment (by dalecurtis):
Agreed on documentation! I'm working on cleaning all this up now, so
hopefully we can reduce miscommunication in the future :) Thanks for your
patience in any case.
Looks like it still an issue today though, so probably worth leaving the
bug open.
FWIW, recreating sync1 and sync2 from wav to ogg using a fresh FFmpeg with
either libvorbis or vorbis (sync2 only) results in files which still
trigger this issue today though. In fact, every file I've tried to
convert to a 30 sec ogg ends up being ~5 secs short.
Here's the command line I'm using:
ffmpeg -t 30 -acodec libvorbis -vn -i <...> <out>.ogg
Should I be doing something else?
