 * component:  undetermined => avformat

Comment:

 So the underlying issue is that `av_read_frame` can return an `AVPacket`
 with 0 size and non NULL data before EOF. Apparently this happens for
 `fate-indeo3-2` and my ffmpeg generated NUT/FLAC sample. The main ffmpeg
 decoding loop has a workaround for this, but any other demuxer/decoders
 (like the ones in doc/examples) would need a similar workaround, or else
 this issue should be fixed in avformat or somewhere else itself.
