This seems to be the correct mode to send, according to the
original RTSP RFC, and matches the method RECORD which is
sent later when starting to send data.

Darwin Streaming Server works fine with either of them.

The strtol() interface makes it difficult to use with
const-qualified pointers.  With this change, although
the const is still lost, the compiler does not warn

This avoids exposing a dummy AVStream which won't get any data
and which will make avformat_find_stream_info wait for info about
this stream.

Also remove one pointless zero initialization in rangecoder.c.

This enables reordering of UDP packets by default, unless the caller
explicitly sets -max_delay 0.

Signed-off-by: Martin Storsjö <martin@martin.st>

Make the muxers/demuxers that use the field handle the default
-1 in the same way as 0.

This allows distinguishing an intentionally set 0 from the default
value where the user hasn't set it.

Passing ttl=0 to the rtp/udp url contexts makes packets never
leave the host machine.

Signed-off-by: Martin Storsjö <martin@martin.st>

This returns 200 OK for OPTIONS requests and 501 Not Implemented
for all other requests.

Even though this doesn't do much actual handling of the requests,
it makes the code properly identify server requests as such, instead
of interpreting it as a reply to the client's request as it did
before.

The rtp demuxer which listens for RTP packets and detects the
RTP payload type will currently get confused if the first packet
received is an RTCP packet. Thus ignore such packets.

Signed-off-by: Martin Storsjö <martin@martin.st>

This avoids (for all practical cases) the issue of reusing
the same UDP port as for an earlier connection. If the remote
doesn't know the previous session was closed, he might keep
on sending packets to that port. If we always start off trying
to open the same UDP port, we might get those packets intermixed
with the new ones.

This is occasionally an issue when testing RTSP stuff with
DSS, perhaps also with other servers.
