WDM Recorder using Software Compression

[sub]

Yes, sub needs to fix the plugin loading code, and then you should see another capture source without the bracketed comment. This doesn't reduce any functionaly, it's just a warning that it's in a sort of "compatibility" mode to deal with the plugin loading code.

Hi norman, good to see back. I'm not aware of aware of a plugin loading issue (or at least cant remember it). What do you mean exactly?

Don't forget to choose which quality profile you're changing before clicking the 'Edit' button to open the Quality Profile Window. You probably want to edit the LiveTVPreview setting.

Worked like a charm... quality looks much better now.

I'm onto my next set of hurdles now:
1.Timeshift and recording were both getting that error "Object reference not set to an instance of object". It went away after I tweaked some audio input settings and encoders, ec... hopefully I won't break it again.

2.Live TV has some sort of interlacing/deinterlacing problem that I haven't figured out yet. Any thoughts on that anyone?

I'm very excited to see you back in action here, Norman. I was starting to think I'd have to return my card and buy a Hauppage... which wouldn't make sense for me since my machine is pretty fast and the processor is fully capable of rendering the video to mpeg2.

Once I get my card working I'll offer up my time to compile a FAQ for the plugin to hopefully free you up for bigger things. I read pretty much all of the 100 pages of posts and a lot of people are running into the same things.

I'm so impressed with gbpvr and this softwareRecorder plugin is amazing. Great work Sub and Norman, let me know if there is anything I can contribute to this project.

Err, the old one with IRecordingSource and IRecordingSourceConfiguration have to be defined on the same class at the same time, otherwise the plugin loading code won't pick up the class correctly. If you pick up a copy of the WDM Recorder plugin and install it, you'll see that gb-pvr config only lists one copy of the plugin (the compatability shim). If you look using RecorderTest, you'll find there are two (the real one, and the shim).

I think you tried to fix this one before, but it broke the recorder plugin loading entirely, so you backed the change out. The WDM plugin should work for any card with WDM drivers, so most of the card you're testing with should work (if the drivers are WDM happy).

mmm, clearly not configured correctly, glad you got it working.

I think I have the same issue, maybe DScaler would help?

well, not really back-in-action. I need to upgrade my GB-PVR (still on 0.97.9) before I can do any bug fixes. Basically I was spening more time on support, than coding - which was taking it's toll.

Once I get my card working I'll offer up my time to compile a FAQ for the plugin to hopefully free you up for bigger things. I read pretty much all of the 100 pages of posts and a lot of people are running into the same things.

cool, the Wiki page was meant to be a FAQ, but it hasn't been maintained properly. Feel free to contribute your FAQ on the Wiki, or you can host it wherever you like and link to it from the Wiki.

You'll have to remind me why you needed this change. I cant remember the reason why you wanted this.

Cant you just implement IRecordingSource and IRecordingSourceConfiguration on the same class to fit in with all the existing recording plugins? Its been this way for historic reason for about three years now.

As I recall Sub, you actually added the requested fix and it broke the plug-in entirely, so you had to back it out to make everyone happy again.

Yeah, I vaguely remember that occurring, but not the reason for it. From memory, norman was going to update his plugin to use this change, but it unexpectedly broke other recording plugins (DBox recorder, SS Recorder etc), which was the reason it was put back as it was.

This plugin had worked in prior to that requested change, so I'm sure it could continue to function after the change was not made. I'm fairly sure this requested change was just one of norman's "nice to have" requests, allowing him to structure his code in a way he was happier with, but not essential to be able to function.

All the other recordings plugins, including my built-in ones, live within this limitation, so I'm sure this plugin can aswell. I'm not keen to risk breaking support for these other plugins again.

I could implement both interfaces on the one class (that's exactly what the shim does), but it lowers the coupling to have the config and the code in two seperate classes. Also if I remember correctly it's only the plugin detection that the code needs to change to detect the IRecordingSourceConfiguration interface instead of the (badly named) IRecordingSource class (it should be RecordingSourceBase or something).

Detecting the interface instead of the class doesn't require changes to existing code, it'll just remove the requirement that the class needs to implement both.

I'll take a look again for the next release.

Ok, I got my V-Stream card to work...woot! Only problem I have now is no live TV on my MediaMVP. It says no tuner available on the screen. What's the trick to getting this to work? Has anyone else had this issue?

When you get a chance, you can try the attached patch for v0.99.12?
