Dear All,
using tee pseudo muxer I faced an issue.
During applying bit stream filters, when the main packet data buffer
is changed, filter_packet function uses a temporary new packet
(new_pkt) to store that buffer, frees the original packet (*pkt), and
replace it with the new packet.
However, in doing so, it forgets about the side data (side_data and
side_data_elems members of AVPacket), which also gets freed by
av_free_packet, but is still referenced by new_pkt. Then, when the new
packet gets freed again in the normal code path in tee muxer, it
attempts to free its side data also which has already been freed.
The solution is simply avoiding freeing the side data by removing that
side data reference from the packet.
This issue is very similar to ticket #3773.
best regards,
Bela Bodecs

Please ignore my patch because Nicolas George also submitted the
solution some minutes earlier.
