This function passes the packet directly to the muxer, without any buffering
or reordering. The caller is responsible for correctly interleaving the
packets if the format requires it. Callers that want libavformat to handle
the interleaving should call av_interleaved_write_frame() instead of this
function.
@param s media file handle
@param pkt The packet containing the data to be written. Note that unlike
av_interleaved_write_frame(), this function does not take
ownership of the packet passed to it (though some muxers may make
an internal reference to the input packet).
<br>
This parameter can be NULL (at any time, not just at the end), in
order to immediately flush data buffered within the muxer, for
muxers that buffer up data internally before writing it to the
output.
<br>
Packet's @ref AVPacket.stream_index "stream_index" field must be
set to the index of the corresponding stream in @ref
AVFormatContext.streams "s->streams". It is very strongly
recommended that timing information (@ref AVPacket.pts "pts", @ref
AVPacket.dts "dts", @ref AVPacket.duration "duration") is set to
correct values.
@return < 0 on error, = 0 if OK, 1 if flushed and there is no more data to flush
