[vlc] jittery video using vlc as RTSP client

[Chris Paulson-Ellis]

Hi,

I can't get vlc to play RTSP video streams smoothly. Playing a stream 
from a device on the LAN or from an Internet stream such as from the URL 
below, vlc seems to frequently jitter as if the frames are being 
displayed in the wrong order. The same streams work fine if I play them 
using ffplay.

With the Internet stream (which is H264/AAC) I get lots of the following 
error:

number of reference frames exceeds max (probably corrupt input), 
discarding one

With the stream from the device on the LAN (which is MPEG-4/G711) I get 
the same jittering, but no errors printed.

$ vlc --version
VLC media player 1.1.9 The Luggage (revision exported)

The problem has also been observed on Windows running VLC 1.0.5 on a 
machine which plays the streams okay using QuickTime, so it seems to be 
a long-standing, non-hardware related problem.
