Mplayer is unable to play the streams. I'll try to find some streams
on the internet that do not use WMV/WMA. Not an easy task... :)
For example, if I try to use mplayer to play:
rtsp://195.122.130.133/Massive%20Mag_xtreme_10
I get the following output:
Connecting to server 195.122.130.133[195.122.130.133]: 554...
STREAM_LIVE555, URL: rtsp://195.122.130.133/Massive%20Mag_xtreme_10
Stream not seekable!
file format detected.
Failed to initiate "audio/X-ASF-PF" RTP subsession: RTP payload format
unknown or not supported
Failed to initiate "video/X-ASF-PF" RTP subsession: RTP payload format
unknown or not supported
As far as I know, when watching TV, MythTV uses an internal player. Is
it possible to play that player independently through the command
shell? I still don't know exactly how these things work internally in
MythTV...
Thanks,
