Graph and TVPI external recorder beta

[sgilani]

CV, have you had a chance to turn off the audio mixer code as it still crashes in Vista and Win 7 in 2.1? (WaveLib.AudioMixer.Mixer.get_DeviceIdDefault() fails; I posted the logs above)

if you don't have time, can you put up the source? the wiki says the source is in the zip, but it's not. :p

Yea - I grabbed the mixer code from some samples and it doesn't seem to translate well to anything beyond XP - I'll see about turning it off since its really only for live preview stuff,

Here is the log snippet that I saved; I'm not sure how helpful this might be.

Couple of points:

This log reports a different problem than I first posted. I think I added the directshow-lib to the GBPVR folder prior to this attempt. Then, this problem occured.

Also, this says graphrecorder is version 1.9, but I'm pretty sure I had the latest installed, file date of June IIRC.

I've since gone back to the January 2009 dll file (1.9?), and everything is working again.

I don't think you need to spend a lot of time on this, unless there is a good reason to update to 2.1.

Thanks.

I guess if it works don't update - if you right click the dll the props should say 2.11 if not I don't know why since I have re-uploaded everything. I did have issues with version control so I may have lost some changes so we will have to work thru that. Just got Windows 7 so I can finally get a version that doesn't error out on the mixers - I will test and release soon.

ok, thanks for the update..appreciate your work!

will be looking forward to your next build.

Can I see some examples of how to fill out the External TVPI tab?

I have 2 Fusion 5 Lites that I'm using for OTA, and I'd like to have one use TVPI for QAM. I've checked the forum and the wiki, but most of the attention is focused on creating graphs.

If I read correctly, I don't need a graph for Fusion HDTV. I have no idea how to fill out the table in the TVPI tab.

Any help would be appreciated.

Thanks.

[carpeVideo]

The tvpi tab doesn't really function anymore there is no need since the fusion 5's now can be driven directly by GBPVR just choose the DVICO or Fusion (can't remember which) QAM source.

Also I released 2.11 should be on the wiki and it works fine with Windows 7 (although none of the audio mixer stuff will work on 7) Remember to delete any errant copies - it now seems to function correctly with the DLL only in the plugins/GraphRecorder directory.

[quote=carpeVideo]I'll try to post my s-video and tuning graph -


Sorry for a noob question, but would you mind re-posting the DVICO SVideo graph again? (the forum has deleted the file from post#16 because it is so old). Might save me some time in understanding is all (noob - remember?)

Thanks in advance ... Adam

[carpeVideo]

Adam,

Unfortunately I don't use the DVICO s-video input anymore I use firewire directly so I no longer have the graph.

Okay, I think I understand this, but I"m not 100% sure.

Is this correct.

The line "Graph - Preview" should point to a .grf file that ends with "Video Render" or "Default DirectSound Device" I have this line set, and this is how graphedit looks, and the channels preview fine. This is nice.

Then for the other lines, "Graph - Low, Graph - Medium, Graph - High, Graph - Custom 1, Graph Custom 2, and Graph - Preview to TimeShift" I should be rendering to a file. This makes sense to me. If I'm watching TV I want to display it, if I'm recording TV I want to save to a file.


So is this right? In GraphEdt, I removed the final rendering, and then just after "WMAudioDecoder DMO" and "WMVideo Decoder DMO" I connect those to "GV-PVR Writer" and then I make up a file name for the sound and for the picture. Is this right? Or is it not this simple?

Yep - sounds about right.

GB-PVR is expecting the output to either be an MPEG2 Program Stream (.mpg), or MPEG2 Transport stream (.ts).

If you go to a .mpg, you'll need to encode the video MPEG-2, and encode the audio to MPEG1 Layer 2, and mux the audio and video to a program stream. (so you'll at least need an MPEG2 encoder filter, MPEG Audio encoder filter and MPEG Multiplexer filter hooked up before connecting the 'GB-PVR Writer').

If you go to a .ts, you'll either need to encode the video MPEG-2 or H.264, and encode the audio to MPEG1 Layer 2 or AC3 or E-AC3, and mux the audio and video to a transport stream. (again you'll need video encoder, audio encoder and MPEG Multiplexer filter hooked up before connecting the 'GB-PVR Writer').
