Comment(by dm at prolingua.co.uk):
I tried out the latest SVN and also noticed that if I tune to a channel
that is not currently broadcasting it does not display the MHEG "off air"
banner. I've done a little bit of investigation and there are several
problems. In the backend it seems that data is only written to the output
file when a keyframe is seen. However when there is no audio or video
there is no keyframe so nothing gets written. Bypassing that test did
result in data getting written to the file. On some channels that
resulted in the frontend seeing the DSMCC stream and beginning to build
the carousel. I don't understand why that only occurred on some channels
and not all.
The frontend, though, seemed to be stuck generating Prebuffering messages
and I suspect that was again because there was no video or audio. I did
try bypassing the prebuffering here and actually succeeded in getting the
banner displayed so potentially this can work.
I hope this is helpful. I don't really understand the code well enough to
propose a patch but I'm happy to help with testing. Although I was
responsible for adding the dummy video for radio and MHEG I always felt it
was a hack so I'm pleased to see that radio at least works without it.
David.
