This was a regression that came in when I switched to using the
h.264 annex b filter all the time. As the filter modifies extradata,
its use violates the statelessness assumption that exists in the
'ffmpeg' command line tool, and maybe elsewhere. It assumes that
a docoder can be reinitalised and pointed to an existing stream and
get the same results.

For now, the only way to meet this requirement is to backup the
extradata.

    threads: change the default for threads back to 1

    Using threaded decoding by default breaks backward compatibility if
    AVHWAccel is used or if an appliction sets threadunsafe callbacks.
    Avconv and avplay still use -threads auto if not specified.

The s->ssrc field is the sender's SSRC, we use ssrc + 1 to get
a collision free "unique" SSRC for ourselves in the RR part.
The SDES block in the RTCP packet should describe ourselves,
not the sender.

This was fixed for the RR part in 952139a3, but wasn't
fixed for the SDES part until now.

This could cause some Axis cameras to send RTCP BYE packets
to us due to the SSRC collision.
