Graph and TVPI external recorder beta

You may try to search on the filter properties and see if it can be selected there and what is the name of "CD In" (That was the case here with "Line In" using a different name).
OK, I'll have a closer look at this tomorrow. When I tested it today, enabling the CD In mixer input didn't work, but perhaps I can work it out. Let's see ...

Audio is a little confusing on windows - there are filters for input mixers in Direct Show but none for output so you have to use two different sets of code. If you use a mixer and don't force the input it will use whatever setting is on the mixer at the time the graph is opened. (which means it may have been muted by a user or another application.)

psicotron is correct the input mixer must be a filter in your graph if you are recording, otherwise the force enabling of the audio won't work since gr is looking at the filters in the graph to set that. There is also another nuance for input mixers you can usually find two filters for the same input - one in "audio capture devices" and one in "WDM streaming capture devices"

In Live Preview using these filters directly in the graph they may have slightly different behaviors one usually lags the video. This is why psicotron requested the option of simply unmuting/muting a playback source (which is on the output mixer) and playing it directly. If you use both I would imagine you'll have two offset audio streams at the same time.

I'll have to do some experiment because just writing this explanation is giving me some ideas as to what the issue might be. All of this can be done manually by playing a preview graph and using the mixer control to see what happens with sound.

Hi,

today I tested the new version of the 1.5. The new audio settings dialog is perfect and works as expected (at least the muting/unmuting part). The problem with my sound card was, the the lines aren't called "CD In" or "Line In" but "CD Volume" respectively "Line Volume". So getting the right line identifier isn't only language related but also audio card related.

Forcing the right input line doesn't work on my audio card, as the filters in the graph get enumerated That is my capture device is called "Realtek HD Audio Input" but the filter in the graph is called "Realtek HD Audio Input 0001" as you can see in the recorder logs:

Code:

I think that's the point. CV, perhaps a laxer comparison (contains instead of equals) can help here?

Using two capture sources (one for SECAM and one for PAL) with the same device ID didn't fix the issue with freezing LiveTV. I really think that this is a synchronisation issue, as both sources are using the same graph and hence the same resources ... It's not a big thing for me, because PAL channels will be received with a PVR-500 in future, but I'm trying to give as much feedback as possible. Additionally, using two capture sources setup didn't let GBPVR selecting the right capture source for recording. I scheduled two recordings, the first on a SECAM channel, the second on a PAL channel. GBPVR recorded both programmes using the SECAM source, because it is the first one in the list and the database states, that the source with this ID can record the requested channel (but tuning it with the wrong video format in that case). See the attached schreenshot anf the recorder log. I will do some more tests using a second set of graphs again and report.

And last but not least, setting the capture size directly in the graph works perfect here. I didn't knew that there are also PIN properties ... Thanks for this advice.

MD - did using two capture sources work for the video? That should close and reload the graphs.

Also on forcing the audio it should still work even with the enumeration issue - for muting it uses the mixer name but for forcing audio it looks at whatever audio mixer is in the graph then looks for the pin name selected. The issue would be if the pin name is different in directShow versus the mixer code.


The attached has more audio logging but no fixes.

Hi CV,

MD - did using two capture sources work for the video? That should close and reload the graphs.

I'm still testing different combinations of 2 catpure sources vs. 2 set of graphs and back-to-back recordings vs. recordings with some idle time in between.

Also on forcing the audio it should still work even with the enumeration issue - for muting it uses the mixer name but for forcing audio it looks at whatever audio mixer is in the graph then looks for the pin name selected. The issue would be if the pin name is different in directShow versus the mixer code.

I made a test recording with your attached version of graphrecorder.dll (see attached recorder log). Muting/unmuting in preview works fine, but setting the right recording source doesn't.

Thanks for your help with this

Media - you forgot to attach the log with your latest post,
also did you set the attributes of your audio filter in the graph (try the filter and the capture pin) to ensure the right source is being patched through?

carpeVideo,

First thanks for making this plug-in, I'm hoping I can get my old ATI TV Wonder VE working with GBPVR 1.0.16.

While I'm a complete newbie to graphedit, I did manage to make a working .grf that seemed to create a working .mpg file that had both sound and video when I played it back in media player classic.

Question is now what? I've installed GBPVR 1.0.16 and v 1.5 of your plugin, imported my epg info, but there's alot of settings in the "graph recorder configuration" menu that I don't understand. I apologize if this is documented somewhere else, I'll gladly go read up if there is....

Could anyone help me with the rest of the configuration? I've attached my working graph at the bottom.

Thanks in advance!

Vortech -

One thing about graph files is that they can not be opened unless you have the same hardware in the machine as the person who made the graph - so I can't open yours. You'll need to post a screen shot.

That said, if your graph creates a file and you are using GBPVR writer filter as the last filter it should be fine for at least time shifted tv and recording.

For your card set up the settings are pretty straight forward. (it get's more complex capturing s-video or composite with audio from a different source)

Start with using only the first graph tab - set all the graphs to your graph except for the preview graphs. Then set try to tune via graph. You probably don't have to force video or audio.

That is it - if you want to do live preview/TV create a graph that renders directly and save that and point to it for live preview mode. Assuming you are using the cards tuner all the audio stuff is not necessary.

Once that is working you can muck with different graphs with different quality settings if you'd like.

Thanks Much, sorry I didn't even think about the screenshot method.......

Will make the changes you recommended and attach a screenshot of my new graph when I get home.

Thanks again!

Looks like I might be having issue with signal strength on my cable TV run down to the basement (too many splitters) but while I sort that out, here's my graph.

[carpeVideo]

From what I can tell things look fine - you may want to set the audio mixer to the realTek and have it select the line in volume for non-preview audio, although I am not sure it's necessary.

Otherwise if its creating an mpg file for you that works then what I said in the previous post should get you going.

To get preview working - disconnect the capture devices , click on the audio video output pins and have graphedit render it - play the graph it - if it works then save that graph and use it for preview.
