Sorry Nico. I should have known better than openly dissing
mplayer in public :)

I think that demux_rtp is fine at this stage. In fact, video
on demand is working *reasonably* well.

The next stage was to implement a new MRL type mcast:// for
reading raw udp streaming over multicast. There is no rtsp
for these streams, but I had to add a little code for the
multicast group joins, and some code to handle the new
MRL type.

The streaming tv server is just in a couple of weeks, and
we've only moved from hubs to a proper multicast capable
switch within the last week or two.

So, I was about to begin testing. However, business pressures
now mean that I need a working udp multicast demo for next
week .. this is a make or break demo, truely. So, I had a
look at vlc this morning and it plays the udp multicast
immaculately. The only slight problem is during channel
change (we are changing channels using either the command
line interface over ssh, or using the http interface) where
on *some* channel changes there is resizing going on which
looks a little bad. It may be aspect ratios, I need to
investigate.

So, I am in the situation where I've modified one player
(mplayer) to support rtsp/udp/unicast .. and it works
reasonably well. I've modified the same player (mplayer)
to handle udp/multicast .. but have problems during playback.

One time in five it will hold a/v sync and play for maybe
five minutes before crashing.

The important stuff for next week is the udp/multicast and
for that I am probably going to have to use vlc, because
it works flawlessly. However, vlc will not (unless I code
it up) handle rtsp/udp/unicast correctly.

So, I'm at a crossroads. Help stabilise mplayer or jump
ship and implement rtsp/udp/unicast for vlc. I'm not sure
what to do at this stage .. but you've always been helpful
so the very least I can do is to submit some proper bug
reports. I'll try and do that as soon as possible but it's
unlikely to be until the week after next.
