The code for demuxing DV audio predates the introduction of refcounted packets and when the latter was added, changes to the former were forgotten. This meant that when avpriv_dv_produce_packet initialized the packet containing the AVBufferRef, the AVBufferRef as well as the underlying AVBuffer leaked; the actual packet data didn't leak: They were directly freed, but not via their AVBuffer's free function. https://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4671/dir1.tar.bz2 contains samples for this (enable_drefs needs to be enabled for them). Moreover, errors in avpriv_dv_produce_packet were ignored; this has been changed, too. Furthermore, in the hypothetical scenario that the track has a palette, this would leak, too, so reorder the code so that the palette code appears after the DV audio code.
