Why break RTSP?

[fly135]

RTSP with MPEG-4 used to work great with our encoder streams, but now it fails with the debug message...

"only real/helix rtsp servers supported for now"

Why break it intentionally?

Whoops sorry, this message occurred when I had RTP over RTSP enabled and I am working on a bug that popped up with that feature.

For some reason the newer versions of VLC stopped decoding our MPEG-4. The debug messages show it receiving data but not decoding frames....

It appears that the pre 2.xx VLC that do work also print the same seq of messages but stops after awhile with the message ....

"no usable vout present, spawning one"

Then the sequence of messages looks like...

[Jean-Baptiste Kempf]

Update to VLC 2.0.5.

If not, force threads to 1.

[fly135]

2.0.5 hangs consuming max cpu for a single thread after buffering is complete. 2.0.3 works with threads=1.
