[fixed] Analog channels - Unable to start graph. (1 Viewer)

[mm1352000]

Thanks Andy!

The issue seems to be that the service is expecting PMT to arrive, but PMT is only relevant for digital streams. I guess the difference between the HD-PVR and Colossus (which do deliver native digital TS streams) and analog tuners (which deliver streams than have to be encoded then muxed) is source of the issue.

Also analog recordings from MP 1.2.3 won't load in mkvmerge ("does not contain any tracks"), and in avidemux 2.6beta no audio can be found.

Hmmm, I have seen one report in the past of the audio not working with a particular codec even in MP. Think it was FFDShow using the two different MPEG audio libraries - one worked, one didn't. I pick this could be an encoding or muxing issue. If encoding, then it entirely depends on the tuner or software encoder that you use (ie. recordings from a different tuner or using a different encoder might work fine - it would all be down to the specific encoding parameters used as compared with the parameters that the decoder can handle). If muxing, then we *may* be able to do something about it. This would be considered very low priority though at present...

Here is my log

I hope this will have a patch to fix it soon as it is not possible to work without the TV module , at least for me . . . .

Dev team please check it asap.

thanks for the great work and for a wonderful product.

I think the culprit is line 304..

someone try change it to:
snip...
_subchannel = subchannel;
Log.Write("card: CAM enabled : {0}", _cardHandler.HasCA);
if (!IsDVB(subchannel) || IsPMTreceived(subchannel))
{
snip...

+add this method:
private static bool IsDVB(ITvSubChannel subchannel)
{
var tvDvbChannel = subchannel as TvDvbChannel;
return tvDvbChannel != null;
}

I havent got the alpha sources around, so I just used github web.
I hope someone else able to compile it

This is "Analog_fix" bin for testing (from Gibman above post):
Do in "cmd" (administrator level)
Net stop tvservice
Copy all files into "C:\Program Files (x86)\Team MediaPortal\MediaPortal TV Server" (backup older files if you want).
Net start tvservice

Now you can try

Has tried this patch,on analog the same error "Unable to start graph",on DVB-T appeared error "NoVideoAudioDetected".
PS:TVServer 1.2.3 with MP 1.3.0 work fine.

@gibman: thanks for providing the patch!
I'm wondering why that PMT check is even there. The TV library will throw a PMT not found exception during tuning (ICard.Tune()) if PMT is needed and not found. In my opinion it is not desirable to have that check in the service at all - the TV service should not have to check a detail like that.

@renault: in those logs the analog tuning error still seems to be PMT related:

start subch:0 No PMT received. Timeshifting failed

This seems to be the same error as before. The TvService.exe is the only file that should need to be patched...

Hi,

I just tried the patch but I'm still getting all cards are busy.

you are probably right, as the tuning has already occurred before we hit this part of the code in timeshifter class.
just remove the check all together
can anyone try this ?.

I think the check has been there forever.
