New submission from Tamas Selmeci <[email protected]>:

Using ffmpeg from SVN, revision is 24872. The aim is to open and play 
MMS streams, thus correct MMSH, MMST and RTSP protocol handling is 
expected.

MMSH and MMST protocols do seem to work perfectly, no problem.

There are certain MMS streams that make ffmpeg freeze. Neither my app, 
not ffplay is capable of loading and playing those streams. Here's a 
list of a few streams:

rtsp://music.outboundmusic.com/OMRadioJazz
rtsp://music.outboundmusic.com/OMEasyMix
rtsp://bostonpete.us/show02-opening.wma
rtsp://bostonpete.us/station02

Interesting is that the problem can not always be reproduced with all 
of the streams above, sometimes all URLs work, sometimes a random item 
from the URL list doesn't work. I haven't found the logic behind this 
"behaviour". I've been trying to "detect" faulty RTSP streams by 
checking the return value of this line of code:

avformat_seek_file (context, -1, INT64_MIN, 0, INT64_MAX, 0)

In many cases, if the stream is a "problematic" RTSP stream, this call 
fails. But not always.

Please have a look at the RTSP and related parts.
