[FFmpeg-devel] [PATCH v2 1/3] avcodec/sanm: ignore unknown codecs in FOBJs

[Manuel Lauss]

Don't error out, just ignore unknown codec numbers and pretend
decode succeeded.  This is useful for older LucasArts titles
which stack a lot of different FOBJs with different codecs into
a single frame.  Mark the frame as corrupt though since we
werent' able to decode everything that is supposed to be visible.
