This one. I must have forgotten to run the test once more
after some last changes.
But do you think the new result is wrong?
Previously it would say "seek ok" and then immediately return EOF
on the next read, now the seek will fail directly (if I read the
diff correctly).
Behaviour seems a bit inconsistent, but only these behave the way
mkv did before, so the majority seem to agree with the new behaviour:
lavf_aif
lavf_al
lavf_au
lavf_ul
lavf_wav
