MATCH_PER_STREAM_OPT iterates over all options of a given
OptionDef and tests whether they apply to the current stream;
if so, they are set to ost->apad, otherwise, the code errors
out. If no error happens, ost->apad is av_strdup'ed in order
to take ownership of this pointer.
But this means that setting it originally was premature,
as it leads to double-frees when an error happens lateron.
This can simply be reproduced with
ffmpeg -filter_complex anullsrc -apad bar -apad:n baz -f null -
This is a regression since
