Does mplayer -dumpstream work for you or have you another tool in mind ?

Sounds possible. You'll have to confirm it suffers the same problem as the live stream. It is possibly that mplayer will fix the timestamps or repacketise the data and so avoid the problem, but it's worth a try.

As expected the dumped stream (with mplayer) doesn't show the problem ... and I do not have enough upload bandwidth to give you access to the stream to test.

I retried just after that the rtsp stream (in a strm file) and it stutters a lot during the first 3 seconds where it drops video frames but the audio stays off sync afterward.

If it can help you here is a mplayer log playing the stream
