I had thought there was a VIDEODEVICE parameter
which was added quite a number of years ago,
although I do not see it documented in the wiki or
release notes (and I have not checked the
source).

Alternatively, another way you should be able to
determine it is that you can use the services API
(Capture Service, GetCaptureCard) and retrieve
the videodevice from within your script.

I have not used them in a long time, but I believe
the MythTV python bindings also have a method
to obtain the CaptureCard information.

And, of course, there is the brute force method
of directly accessing the mythconverg table and
'select videosource from capturecard where cardid=...'
although that would not be recommended.

You are right: I do see VIDEODEVICE in the source.

I just tried adding it to the wiki, but I don't know how to edit the
thing that {{Event_and_Job_Parameters}} refers to on page [[MythTV
System Events]]. There isn't a page of that name.

I will give VIDEODEVICE a go.

By the way, it would be useful for a special parameter to exist that
could be passed to the "any event" event, showing which parameters are
valid for that event, such that logging $* from the "all events" handler
would yield something like:

REC_PENDING CARDID %2 CHANID %3 STARTTIME %4 RECSTATUS %5 VIDEODEVICE %6
VBIDEVICE %7

with the %{1-7} parameters filled in.

Cheers, Jan

Hi, it's a template, not a page (the same text is used by 2 pages.)
Check for templates at the bottom of the page when trying to edit
it.

Thanks.

I added a %VIDEODEVICE% entry to the table, but I don't know what to put
in the used by and released in columns so I left those blank.

v30 (at least). I didn't see if it was backported. Updated the template and
added VBIDEVICE which was done is the same commit back in Aug. 2017.

Thanks Jan and Gary (good memory).
