WDM Recorder using Software Compression

[JawBone]

Thanks normanr for responding.
I'll get everything together after work today. Stay tuned.

Mystery solved!

I had all day to think about it, so I decided to go back to square one.
I pulled the card back out of the pc, and wrote down every number or letter there was. When it came time to reboot, and load the driver(btwdmdrvinstaller5.3.2.zip), I noticed the tuner setting that is used to configure the driver was auto before. I changed my settings to Temic 4032 FY5, and TDA9850, and voila!
No more Unspecified error.

Now I am investingating why the recordings I set are failing. I tried to Quick Rec the Simpsons, and it failed. I'll keep pluggin' away.

Thanks for your help!

Okay.
Now I got it to record video, but for some reason audio is not being captured.
When I play it back, I have video, but no audio.
I have attached a screenshot of my Software Recorder Configuration.

Any help is greatly appreciated.

The InterVideo encoders are 'untested' so I suggest you try the Elecard, Moonlight, or ATI encoders. The audio problem might also be related to the playback, so try different audio decoders. I assume that you have the external audio cable running from your tv card to your line in?

hmmm,thats the first place i looked, but for that filter it says the file is ksproxy.dll which is the directx file..so i know i don't edit that...
and the funny thing is, it shows one less pin than the filter provides!
[supposed to be 7 pins out, but only shows 6!] i'm so confused!
attaching pic..
i would love the xml graph playing ability...would make any card possible that can have a graph built,and totally lock it into those filters which would be invaluable,as winblows is so unpredictable when any changes are made to the system... also thatway people could snag the graph of their 'working' capture app and use those to start with...

[not to mention it would allow the programming of the ati and other compressors! ability to set bitrates and such on all the filters! the holy grail for software cards! ]
seems the graphs retain these properties when made with graphedit..
even days later i open the graph,and it's exxactly where is set it on all the filters....channel, pins connections,mpeg output filter properties,etc...
looks like the data is in the xgr file that sets the filter properties, noticably the ati encoder settings!
example:
<FILTER ID="ATI_MPEG_Multiplexer" clsid="{7A10E1E1-F430-11D2-8E75-00104B93CF06}">
<PARAM name="data" value="0300000000000000000000000000000000000000000000000000000000000000"/>
*****
apparently the 'data' is the settings for each filter and if we could keep those once set,it would mean totally settable encoder properties,and this method should work for all the other encoders as its a standard way to set the properties..
may not need a SDK to all the different encoders if you can figure out how to send that data when building your graph...
have you noticed the low cpu usage of the ati encoders? amazed me..
less than half on my machine than any others i've tried..
the raw graphs are less important than getting the filter params to stick..
[tho i would totoaly appreciate getting my theater200 chip working!]
i appreciate all your work..as i'm sure do many others,without it we'd be hosed.. lets us enjoy some "real" pvr software!

No actually, line-in is what it defaulted. I tried TV Tuner Audio, and CD Player. Currently I have a cable inside the machine that connects the CD player to the STB card, and from there to the motherboard. I normally change the volume via the CD Player's volume. I have and tried the Elecard encoders as well, but no sound. I think you may be on to something with Playback tab. I have not messed with the settings there much, yet.
I will download the Moonlight and ATI encoders, and try those.

Any suggestions you think to add are appreciated.

Thanks Again!

I am using the STB TV PCI card with the Intervideo encoder.

I had the same problem with no audio when recording, and the same thing occured in time shift mode, except after i changed channels in timeshift, the audio would start working. I tried the tune twice selection, but that didn't really fix it either.

So I modified the software recorder source code and managed to get it working. What I did was modify the startRecording procedure...

after the "int hr = mediaCtrl.Run();" call, I added the following

hr = mediaCtrl.Stop();
setTuning(channelTuning, false);
hr = mediaCtrl.Run();

This is the same set of commands that was making the the timeshift mode work after a channel change.

Perhaps normanr will be able to look at this and see what is really going on rather than the hack job I did.

I also had another issue with the SetAudioPreviewPinState procedure because the name of my mixer for volume control is "Realtek HD Audio output", but the mixer for recording is called "Realtek HD Audio input". So my audio running through the sound card would not get muted when going into timeshift mode or when recording. I ended up adding some code to find my mixer, but it maybe easier if this was configurable, I'm not sure how prevalent this issue is.

oo,i have same stb card card too...very old..
[assuming you meant STB TV PCI not TC]
what drivers are you using? the generic ones?
would be interested in a fix as well...similar probs here..

[kmtrue]

Yeah STB TV PCI veeeeerrrrry old

I am using the BTwincap drivers.

If you can get audio to work in timeshift mode after a channel change, then you should be able to use the same fix.

[JawBone]

Likewise the Btwincap driver is great.
You can download it from here http://btwincap.sourceforge.net/
Just be sure to set the chipset, and tuner settings manually or you will most likely have problems.

Back to the time-shift issue. I remember seeing something about timeshifting, but I do not recall where or what setting page I saw it.

Is there a detailed doc on this plugin with setting descriptions. Most are common sense, but a few make me go hmmm...

Seeing how the sound comes through the CD Player line in, I have changed my settings to reflect that. I notice that it keeps muting on its own, though, whenever I go to record. Any thoughts?
