[Redbutton-devel] Problem after retuning with Freesat

[John W. <jo...@po...>]

Hello,

I'm trying to get the redbutton program to work with a DVB-S card and
the BBC "Freesat" service. Actually, I'm trying to convert the code
into a plugin for the VDR program.

If I tune into BBC1 and run "rb-browser" then all goes well until I
select an option from the menu that causes it to re-tune. For example,
today there's an option that causes it to re-tune to "BBC Stream 35"
which is showing a programme about folk music. This service is on a
different transponder (12441MHz instead of 10773MHz). The re-tuning
works OK and I see the new programme, but rb-browser then tries to
re-initialize and looks for ~//a or ~//startup. Neither of these exist
in the new service, so after a few seconds it gives up and exits.

There are certainly some carousel files being downloaded from the
"Stream 35" service, so I suppose rb-browser is looking for the wrong
thing, but I can't puzzle out what.

I've got a spec (mheg_profile_106.pdf), which says the initial file
object can be sent in the ServiceContextList, but the debug output
shows this is empty. There is a file "/app/a", so I tried hardcoding
this as the initial file instead of "/a"; it read the file and then
tried to find "/boot", and neither /boot nor /app/boot exist, so that
didn't work.

Any suggestions on how to debug this would be welcome, as I'm stuck.

Regards,
John Williams
