Would it be possible to use GraphEdit to figure out how the WDM Recorder plugin (written by Norman) renders audio?

You can probably figure it out from the configuration file.
You might also try the recorder test - not sure if he put a save or last graph function in there like GBPVR does. Did you try using AC3 filter ? I have wierd sound problems on occasion but I tend to think it is due to AC3 coming from firewire and using a SPDIF out. This is the one problem with graphs it's nearly impossible to debug anything remotely since machines filters are set up differently and have different filter priorities. I am really confused that you can't get ATI's own simple render graph example working. CV

Disclaimer : I just discovered GBPVR about a week ago and just happened to stumble onto the page for this plugin because of your posts mentioned a AIW Radeon. I really don't know what I'm doing and everything I'm telling you might not be the best way or even the right way to do everything.
My problem with audio not playing was a codec problem, I installed FFDShow and it now works with no problems. topperdude: [INDENT]which AIW Radeon do you have? Mine is the original Radeon (no numbers after the model name). I'm not sure if later models have the same hardware on them as mine. As soon the tuner device starts, it starts sending audio on the line out cable. To watch live tv, you need to be hearing this audio as soon as it hits your sound card. The input on the soundcard must be unmuted in windows playback (not recording) options for live TV. Plug a microphone into the port where you currently have your AIW line out going to and test it out, as soon as you talk into it, you should hear it coming through your speakers, even without any other programs running. If you don't hear anything, then your settings in volume control are wrong and the input you need is muted or turned all the way down. Try that and see if you can get audio. However, once you get it working for live tv, you're going to have to go back and mute the live audio. Since the AIW is outputting audio any time that the tuner is open, if you try to timeshift , you're going to hear both the delayed timeshifted audio of the recording and the live audio coming from the AIW playing directly through your soundcard. I haven't found a way to automatically mute the live audio when not watching live tv, so on the Misc tab in GBPVR's config, i unchecked "Use Live Preview if possible" and muted the input in playback options. My Live TV in GBPVR is always timeshifted and I'm always getting the audio from just the recording.[/INDENT] carpeVideo: [INDENT] 1) Is there any way to save the Filter Properties with the graph? For example, if I right click on the ATI Video Encoder filter and goto Filter Properties , I can set the bitrate and quality settings for it. However, if I close graphedit or use the graph in GBPVR it just uses the default settings. I can't figure out how to set a high/med/low recording graph since it always defaults to the same settings. 2) This is more of a pet peeve than a bug in your program, but the tab order on the form is all over the place. I tried to paste the same graph into every box, and the cursor jumped all over when trying to tab between them. [/INDENT]

Burning -
I think topper mentions that audio works with GALLM and the software recorder - which really means his issue is with the graph - although perhaps with all the changes he has done he has fixed one issue and caused another not sure. As to graph properties I assumed they got saved with the graph as well -- this wasn't the case with the mixer and that is why "the force mixer option" exists I'll try a few tests - it may be a filter by filter basis since I think others are using it with success. As to tabs - I'll take a look for the next release - it wasn't something I really looked at. CV

I have the original AIW Radeon (w/o any numbers) - so its probably the same generation of card as yours. Which version of drivers and MMC do you have installed on your PC? I am using the drivers that came with MMC 9.02 (from Oct 04) as this is the last version that is known to work well with pre-9250 Radeon cards, per the folks at Rage3d. CV I did try AC3 filter, but no luck! What is confirmed is that there is no audio being encoded in the mpg file at all, because even when I directly connect the Audio Decoder out pin from the Audio Xbar to the sound card and then to the directsound renderer, I do not get any audio. So the problem could be with the Audio Xbar or the ATI TV Audio filter or the ATI TV Tuner. The next thing I am thinking of trying is to see if I can directly connect the Analog Audio from the ATI TV Tuner to the Audio Tuner In pin on the ATI TV Audio Crossbar. Not sure if it will connect the two, but at this stage I can't think of anything else. The other thought is that installation for some required ATI Audio component may be messed up. For example, I see a filter called "ATI WDM Audio Tuner" listed under the same group as the sound card filter (Vinyl AC'97 Audio (WAVE) in my graph), but whenever I try to add the "ATI WDM Audio Tuner" filter, GraphEdit says "Unable to add filter, resources for this filter may already be in use" or something similar. BurningDog - can you check in your graphedit whether this filter shows up (it should be in the first group at the top of the "Insert Filter" dialog box). If it does show in your list, does it allow you to Insert it to the graph? If so, I may have to re-install my ATI drivers (although I have read in other posts in rage3d forums that uninstalling ATI drivers can be a pain and not a guarantee that everything would be removed). But atleast checking for the above filter can give a clue about whether the "ATI WDM Audio Tuner" filter could be the missing link. One thing about GALLM is the recorded shows are in avi format and not mpg. So it seems its not using the ATI MPEG filters as in my graph. Not sure if this matters, but just thought I'd post it. Thanks for your help and suggestions, -Topper

I'm using the very latest drivers from ATI. Cat 6.11s, Encoder 6.6, and MMC 9.14. They quit supporting older cards in MMC for awhile, but the newest one seems to work. Everything I'm using is linked here : http://ati.amd.com/support/drivers/xp/ai...00-xp.html
I don't have the ATI WDM Audio Tuner, all thats listed is my sound card.

Well, FWIW, looks like GBPVR is finally working, although I'm not sure how. All I remember doing was running chkdsk during startup. Only thing chkdsk found was some "free space that had been marked as in use" or something to that effect.
I then ran GBPVR's config tool and thought I'd try to configure the Software Recorder Plugin once again to see if I atleast get sound like I used to before and if that graph can be imported into GraphEdit. So, after instructing GBPVR to use the Software Recorder instead of the Graph Recorder plugin, I configured the Software Recorder with the values shown in the screenshot attached to this post. Saved the changes, closed Config Tool and braced myself while bringing up GBPVR . BOOM - When I clicked on Live TV, I got both audio and video! Finding it hard to believe, I went into TV Guide and switched to a different channel and could watch that as well with audio and video. I then tried timeshift and that worked too! As things started to sink in, I got a bit bold and decided to exit GBPVR, downloaded ComSkip and configured GBPVR to use Comskip. I just copied the three basic Comskip files into the GBPVR folder and scheduled to record a half hour show. To my pleasant surprize, it recorded the show and marked the commercials as expected. I then tried running the graph that was used with carpeVideo's GraphPlugin (same as BurningDog's graph), but that still didn't render audio, video was just fine. So - long story short: a) GBPVR is currently working on my computer with the Software Recording plugin, although not sure what fixed the problems. b) Graph plugin still has no audio. carpeVideo had previously suggested the configuration file would have the settings/filters/graph/etc. used by Software Recorder plugin which could in turn help figure out the problem with my graphEdit graph (used by Graph plugin). Not being familiar with these, I'd appreciate some help in where I can find the configuration files and what should I be looking for in these files. I can even post the files here if someone more experienced can identify something much quicker than I would. I am hoping to get the graph working with audio using carpeVideo's Graph Plugin so that it can be shared for future reference in the thread started by carpeVideo in the community area. BTW, anyone know of a good (preferably free) backup program that I can use to image out my current HDD? That way if something messes up down the road, I can get back to a working state pretty painlessly. Thanks, -Topper

What your softwareRecorder config is saying is that you are using the audio card for capture (from line in) with not inputs attached to it in the graph.
Try a graph with just the audio card (no ATI stuff) make sure the mixer is set to record from line in and render it. See what happens. Then try your orig graph without the ATI audio and just the audio card and see what happends. Of course if software recorder works for this you don't necessarily need the graphRecorder anyways, CV

carpeVideo Wrote:What your softwareRecorder config is saying is that you are using the audio card for capture (from line in) with not inputs attached to it in the graph. By "no ATI stuff", do you mean NONE of the ATI components (incl ATI Tuner, etc?) OR are you referring to specific components (e.g. leaving out only the ATI Audio Xbar component). Reason I ask is if I leave out ALL ATI components, then what would be the TV audio source when I play the graph. Reason I'd like to get the graph working would be: a) Learning experience for me to help figure out why there was no audio. This can be helpful in case I need to build a new graph in the future for a different card or even if I want to help some other newbie in a way that people here have been helping me get up to speed. b) Software Recorder is a non-supported plugin, so if something goes wrong down the road, alteast I would have another option with the graphRecorder. Thanks for your help, -Topper

Yep, I literally mean no ATI stuff. Basically the first one would tell you if the tuner is always tuned and simply always dumping the audio to your card.
You can probably also tell this simply by unmuting line in and turning it up. The other would mean it dumps audio through the physical connection only when the tuner filter is active but it is pretty close to the same thing. My guess is if you could see the software recorder graph it would have the tuner to a crossbar with video out, and then your audio card to the multiplexer directly. I'll look in the software recorder test exe and see if it has a save graph function - if not I can probably add it just for grins. It will be at least 10 days since I'll be out next week. BTW even though it says unsupported normanr is back on the forum lately and modded it some last week I think, CV |
