Graph and TVPI external recorder beta

[carpeVideo]

That's a weird stream that works only in WMP and not VLC.

I tried my stream with VLC, and I've had a few quirks so far though I do have preview working. For me, preview starts with both external recorder and graph recorder fine. But for some reason, with graph recorder, the stop Preview never executes. To stop, I run vlc with the vlc://quit command and the 'only one instance' flag also set. Also, I notice a quirk that there's no postRecordingExecutable entry in my graphRecorderCfg.*.xml files. I assume this feature is still under construction? (This might be user confusion.) For now, I'm just using external recorder.

Hmm - the executable only gets saved if you browse to it not if you type it in I 'll see if I can figure out why,

My hunch is there's some sort of redirection going on in the background that only WMP is being able to handle or something.

The stream is below, if anyone's interested. I'll probably just try to look for other ones somewhere on the net.

I attemted to connect to that stream but it failed. I then attempted to go to the website and stream from there but this caught my attention:

Steps 1: Please register on our site to become a member.
Steps 2: Once you have your id and password, go ahead and select the cricket package you would like to watch and pay for it.

That stream most likely contains DRM and will only be viewable on a DRM capable player like WMP.

ahh...guess they changed the site to be pay-based now. Bummer ; guess I'll have to find another one.

Something funny is happening for me with the 'Stop Preview Executable' and maybe with some of the other options in the 'External Via Executables' section. I set all the Executables to point to c:\windows\notepad.exe and I set the options to load various files.

So far, I'm only seeing my 'Start Preview' notepad execute. When I press Play I see 'Start Preview Executable' run -- but when I stop, I'm not seeing the 'Stop Preview Executable' run. So far I haven't seen evidence of the 'Start Recording' or 'Stop Recoding' being executed either. I did tell it to record my test channel and didn't see notepad pop up once.

I have this idea of using this feature to launch and shut down the tvants software -- but I can't get it to work yet.

Post the logs and your graphRecorder config and I will take a look,

Alright, thanks. I uploaded logs to

http://www.mataga.net/mataga/gbpvr/

http://www.mataga.net/mataga/gbpvr/PVRX2.exe.log
http://www.mataga.net/mataga/gbpvr/graph...Cfg.36.xml

I did spot this in the logs -- I think this is the relevant portion. The notepad command does execute properly, but then it looks like some kind of error occurs. Maybe I just need to set a preview graph also? Is that required?

It looks like you are using live preview mode and their is no graph to refer to so it blows up - I added an error catch in that routine if you want to try the attached dll although it may still error out elsewhere if you use live preview.

In general you should use timeshifted for external recording exes. Here is why.

For 'live preview' gbpvr calls start program and expects a graph with no renderer returned. So if there is no graph it will likely exit viewing with an error even if your exe calls work.

For 'timeshift' gbpvr calls start program and expects a filename returned (graphRecorder returns the filename given to it by gbpvr plus any extension changes if the last filter in the graph is not writing an mpg) In addition, it checks that file to see if it grows (as does graph recorder) if the file does not grow it exits timeshift/viewing. Later gbpvr asks to stop recording, this is when the exit executables are run. Therefore a notepad call alone may not get you all the way through the process either since there will be no growing file.

[cathrynm]

Oh, okay, I see. I was just trying to get sense of how this system worked first. I'll try your executable, but I guess my next stage is to study vlc options for getting the reencoding to work properly for time shifting mode.

Does graphrecorder work with Win 7 32bit? I have firewire capture working and have graphs that work in Graphstudio, but I just get a black screen in GBPVR using the preview graph. I used the same graph design (not the same file) in XP, so I don't think it's a graph problem. I can't find any errors in the logs. When I stop the preview, the ActiveMovie window appears momentarily and it is black before the PVRX2 screen comes back.
