[streaming] Streaming or dumping from receiving sdp stream

[Siegfried Wagner]

Hi,

today I posted my question into the public web forum. But I also want to
ask it here:
I'm trying to watch DVB-H streams with vlc and thanks to the
improvements of H.264 decoding this really works fine now!

To watch the ip-encapsulated video and audio data I need to start vlc
with the appropriate sdp-file (see below). This includes two different
ports on the multicast-ip with one for video and one for audio.

As mentioned this works fine for just playing. But I need to re-stream
this stream, and here is where the error occurs: In the best case I can
manage to dump audio to a file, but never video!?

For example with
":sout=#duplicate{dst=display,dst=std{access=file,mux=ts,dst="vlc_record"}}" I can listen to the audio but no video is shown, and the same is for the recorded file. 

Stream information is always correct: 
Stream 0: 
Codec: h264 
Language: 
Type: Video 
Stream 1: 
Codec: mp4a 
Language: 
Type: Audio 
Channels: 2 
Samplerate: 48000 Hz 

But the statistics show that there are no video frames decoded. 

Without any sout parameters I can see the video without problems! 

So I guess there is just something wrong in the processing chain, so
that streams consisting of more than one sub-stream cannot be
re-streamed. 
Am I right? 

Thanks for your help! 

Below this is the example sdp file I'm using:
