<p class="MsoNormal" style="text-indent:.5in">I’m using version 2.7.2 and I’m trying to retrieve block additional side data from a matroska file. Whenever I do an av_read_frame the side data is missing in the resulting packet. Debugging matroskadec.c I can
see that the side data is being read into the internal packet but it looks like this data is lost when it is copied over in matroska_deliver_packet as that only memcpy’s the AVPacket structure. Is there a different way I should be doing this to get access
to the side data in my file? I’m also concerned there may be a memory leak when an mkv file contains side data as the internal queue packets are only freed with av_freep in matroska_deliver_packet vs using av_free_packet like is used in matroska_clear_queue,
but I may be missing something.<o:p></o:p></p>
