I still do not think that this ff_rtp_merge_data_packet() is ok.
Why not using (for example, maybe there are better solutions...) a
ByteIOContext? I mean, when you receive the first packet of a frame you
call url_open_dyn_buf(), then every time a packet arrives you call
put_buffer() to append the payload to the ByteIOContext. And when the
latest packet arrives (M = 1), you call url_close_dyn_buf() and you pass
the resulting buffer to the ASF demuxer.
