GB-PVR File Writer compared to Hauppauge WinTV File Writer

[VijayS]

Hello,

We're developing a solution for schools to use multiple WinTV PVR cards to record using multiple cards.

Once I installed 2 PVR150s I installed all drivers and then I discovered GBRecord, which was a great app to test the system performance of record from multiple sources.

I now need to re-create these capture graphs in DirectShow. When I try to do this using GraphEdit I can't get the Hauppauge File Writer to produce an openable file. When I use GB-PVR Writer, it records perfectly as it does in GBRecord.

What are the differences between GB-PVR Writer and Hauppauge File Writer?
Why doesn't the Hauppauge File Writer work properly?
Am I allowed to redistribute "GB-PVR Writer" in my applications?

Thanks,

-V

Sorry, no you cant distribute the 'GB-PVR Writer' filter with your application, but you should find the standard 'File writer' does effectively the same thing. The GB-PVR Writer is pretty much the same as this, plus a few additions to allow recordings to be played back will they're still in-progress, and a few other GB-PVR specific things.

I dont know anything about the Hauppauge File Writer, so I cant really help you there.

I didn't think I'd be able to. I'd just thought I'd ask anyway.


When I try the default DirectShow "File Writer" and press play graphedit says the error:
"The Graph could not change state. One or more arguments are invalid (Return Code: 0x80070057)"

Why would this error show up when the graph works fine with the GBPVR Writer?

I've just tried now and it seems to work fine for me with the 'File writer' filter. I'm not sure why it wouldnt be working for you.

hi, sub

the standard File Writer can't "allow recordings to be played back while they're still in-progress". how to do it, can you give me a clue.

thanks!
