graphRecorder: capture source disappears after setup

[Jay D. Carter]

Hello!
I hope this is the correct forum for this issue..

I am trying to set up a capture source for a Motorola DC62xx cable box using firewire. I have created graphs which appear to work. I setup all the settings on the Graph recorder tab (A), configure the EPG, and all the settings are accepted without any errors. I close Config, then re-open config and the new capture source is missing!

A .ZIP of my logs folder is attached... the config log shows this:

2009-01-18 11:23:12.031 ERROR [1] Error creating: ExternalRecorder.ExternalRecorderConfig

...I did install the ExternalRecorder plugin before, but decided to switch to the GraphRecorder plug in. I tried removing all the External recorder files, and also tried adding them back to the proper folders. In both cases I still get this error in the log.

Any suggestions would be appreciated!

Thanks,

Tried renaming the gbpvr.db3 and built a new one with just the Graphrecorder capture source - it is staying put, so I must have had a corrupt .db3.

Preview graph is not working reliably - it stops working and will not start again for a while. Capture graph works in Graphedit but not in the plugin...still researchign this, but any suggestion onthat problem will be appreciated!

I have also not been able to get the preview to work reliably. It starts once, and can channel change OK, but if stopped, cannot restart without restarting PVRX2. There's a thread here where I asked about it, and Carpe suggested perhaps the filter graph wasn't tearing down when preview is stopped. Also, I'm using FSE which might also be a factor. I think he's right. I gave up because it's not important to me - if I want to surf, I use the TV!

My capture to mpg file graph uses:

AV/C tuner device -> Nvidia TS info parser -> MPEG2 demux -> ATI mux -> GBPVR file writer with mpg extension

I don't know if the info parser is needed, but this works for me- converts TS to PS. I find that GBPVR cannot play the TS files reliably.

AV/C panel device -> Nvidia TS info parser -> MPEG2 demux -> ATI mux -> GBPVR file writer with mpg extension

This graph is good for timeshift but not live preview - live preview needs to render.
[AV/C panel device -> TS Parser->Demux->Decoders->Renderers] Also now that .ts support much better for timeshift and record I am using [AV/C panel device -> TS Parser->GBPVR file writer with .ts extension] with good luck. This cuts down on the cpu usage. I believe the Nvidia TS Info Parser is cutting the transport stream into one program and that is why its necessary.

CV: I'm hijacking this thread, but your comment about recording TS caught my eye. Since upgrading to 1.3.11, 3 of 4 TS files I recorded will not play; the MPEG2 demux does not connect to any downstream filters. According to MSDN, the MPEG2 demux will not work in "pull" mode from a TS file. Does Sub add a pull-push filter in front of the demux to make it work? These files play fine in WMP or Graphedit using the Nvidia transport demux (which can only connect to Nvidia decoders). Any thoughts?

Not sure what sub does - but I have specified a different demux's (has to be done by hand in the config.xml file) and I am using "MPEG splitter" filter which i think is from the MPC Home Cinema filterset, I have had good luck with the gpbvr parser as well for playback,

OK, now I cannot get either my preview or capture graphs to work in GBPVR, even though they work fine in GraphEdit. Channel change takes place, then I get a black screen on preview. on capture, the folder and file is created but never grows beyond about 2k. This is the only clue in the recordingservice log:

Preview graph is Moto AV/C Tuner --> NVIDIA TS Parser --> MPEG-2 demux -> (ffdshow audio and video decoders) --> (Default waveout device and video renderer)

capture is :
Moto AV/C Tuner --> NVIDIA TS Parser -->GBPVR Writer (tried with both a .mpg and .ts extension on the output file)

What else can I do t troubleshoot this?? The preview was working a day or two ago, but not reliably (would work several times, then stop until I rebooted).
Thanks!

I'd really need to see the whole log - I don't even see graphRecorder being invoked in that snippet.
