BBCi channels play with no video (DVB-S)

[BigMoose]

A while ago Sub fixed the issue of the BBCi channels not appearing in the scan and they worked fine. However something has gone wrong in the last few weeks and now I get a blank screen with audio when I try to watch them. I cant put an exact time on when it went wrong, ie if it was installing 1.5.36 that caused this. I have a feeling that it stopped working shortly before I upgraded to 1.5.36. The log implies he has no idea what the video feed is and doesn't bother attempting to create a graph including the video. Logs attached.

Can you make a short recording available so I can try playing it here?

If you mean the streams, I've just tried and I get a blank screen with them on live TV, but recording and then playing seems to work.
a very small sample of the recorded files is at http://dl.dropbox.com/u/13497428/%28no%2...02130-0.ts

(p.s. first time I've tried the public directory of dropbox, so sorry if it doesn't work!).

I can download that fine and it plays in media player on my laptop. Not tried recording the streams on the pvr box, but will do next time I want to watch something. Sub, can you let us know if that sample from Martin is long enough?

I wonder if removing the imondisplay plugin would help?

Thanks - though if recordings play fine, this probably wont help me get to the bottom of it.

Is this a H.264 or MPEG2 channel?

It seems this channel is using an invalid type '82', which isnt officially either MPEG2 or H.264, but I can probably hard code "82" as one of these to get it going.

When I play on the NMT it is normal type 2

The service type I'm refering to is from the SDT table, collected at scan time. The app needs to know this in advance, before it sees the stream, so it can initialise the demultiplexer for the correct media types. Directshow makes some of this tricky, because its got to be done before I get any data.

When it has the advantage of existing files, like the playing a recording, it can correctly determine type - like the guys said above where recordings are playing fine, just problems for live tv.

Ok sorry, mvpmcx2 treats everything like a file so I can get what it needs from the PAT before playing.
