Thanks Sebastien and Frankie for the replies.Frankie, i can see that once the device request for second channel in parallel dvb daemon is trying to reuse the same pipeline and in case channel is not part of active channels it's adding the tee and sink element to the pipeline. However, instead of on-pad-added callback looks like rtspmedia is calling unprepare and from gstreamer logs it looks like it's throwing internal flow error.0:05:26.309144326 ?[332m 3151?[00m 0x201fc30 ?[32;01mINFO ?[00m ?[00m rtspmediafactory rtsp-media-factory.c:467:gst_rtsp_media_factory_construct:?[00m constructed media 0x222feb0 for url /1/8511/Accenture_ABIC_Accenture_

With regard to mpegtsparse, does it mean mpegtsparse needs to be fixed ? Is there a patch already available for the same?Sebastien, i was myself planning to try out the recording part or atleast extracting the two DVB streams together to a file sink using gstreamer pipeline. I'm going to try that also. But i'm able to configure two channels one at a time without issue. And both the channels are configured at same frequency in channel.conf.My observation also is that every time sink element/payload is created with the same name "pay0" and then gst-rtsp actually uses this further.Is this the correct behavior? I'm not sure as my investigation is still on but somehow felt little suspicious on this.Gst.Element payload = Gst.ElementFactory.make ("rtpmp2tpay", "pay0");

Dear Vijay,
mpegtsparse parses the PMTs and configures dvbsrc with all the PIDs corresponding to a program SI.
It should be possible to parse multiple programs on a same transponder but mpegtsparse needs a patch.

Dear VIJAY,
it's true that watching multiple channels on the same TS should work,
I'm not sure if/how it works with respect to rygel, though.
What you could try first is to schedule two recordings at the same time
on two channels on the same TS. This way we would be able to narrow down
the cause, whether it's caused by streaming or not.
Best regards,
Sebastian
