GO Chipset Audio Question

[sub]

Good spotting.

I actually think its a combination of a couple of things. The TV Walker seems to only a allow a PCM bitrate of 32000, wheras GB-PVR is trying to set 48000 - which is valid for it's close relative the Plextor PX-402U.

Also, as you point out, the Intervideo audio encoder isn't compatible with this audio stream from the TV Walker (possibly because of the bitrate). I dont have the InterVideo software installed in the same machine as my TV Walker, so hadn't noticed it.

Try the attached patch which will prefer the HT Audio Encoder for the Walker or Typhoon devices, and will do a much better job with handling audio bitrate discrepencies.

BACKUP YOUR ORIGINAL FILE FIRST.

OK. I shut down the app and the service, and replaced the DLL. I also re-registered the Intervideo codec. Now, my mpeg Manual Recordings are working, but the Divx recordings are not. I notice right off that the Divx mode is not being specified, nor are any bitrates. Here is the logfile:

Thanks! This is so close to working, I can taste it!

Actually, are you 100% sure your replaced the DLL inc C:\program files\devnz\gbpvr, because I also removed the @1, @2, @3, @4, @5 and @6 log messages at the same time? These are still shown in your logs.

[hitek146]

I had replaced the DLL, but it didn't fully implement for some reason, as you could see in the logs. Maybe it was cached, or something? I copied it back this time, rebooting, and this did the trick. Note that it still breaks Timeshift mode, as now the Timeshift mode uses the HT MPEG encoder, and I don't think the Intervideo Mux wants to work with it. It's starting to look like the Intervideo filters don't get along with some other filters very well..... I unregistered the Intervideo Mux, and now Timeshift mode is using both the HT encoder and mux, and everything seems to be working very well now. Is there any way for those of us with WinDVD Creator installed to not have GB-PVR use Intervideo filters at all, unless it is a last resort? Unfortunately, I do need the Intervideo decoder, as it is the only way I can display LiveTV smoothly....

I'll do the same change for the multiplexer, which will force it to use HT one if you're using a Walker or Typhoon. I'm at work now, so cant make the change until tonight.

If you dont have a walker or typhoon, then it'll continue to prefer the Intervideo filters, as this is what is done in the WisChip's SDK for the GO7007SB devices.

[KingArgyle]

Hey, guys. Thanks for tracking this down. I look forward to finally being able to record shows in DIVX.

Thanks again for the hard work on this. I'll try the DLL that was posted. I currently only have the Intervideo decoders installed because of WinDVD, but I can use PowerDVD if necessary instead until this is fixed.

[sub]

I've attached an updated NativeUtilities that will prefer to use the HT Mux for the TV Walker or Typhoon. Let me know if it works.

Of course the mux is only used for MPEG1/2 video, so it wont make any difference to Divx over the behaviour of the last patch.

[hitek146]

It appears as if that last DLL did the trick, but I notice in the logs that the software is not preferring the HT codec, it is just &quot;erroring&quot; into it, which is making it take longer than usual to build the graph. Any way to make it try the HT codec first? Here is the log with the new DLL:

It does work, but it always kicks me out of timeshift mode after viewing for a short time, even when using the original DLL. With the original DLL, the error is trapped, and with the new DLL I get a Windows error with the option to debug. I don't recall this happening before, but then again, I never spent much time in Timeshift mode until I got Divx recording working.... Attached is the error I got using the original DLL.

This all looks correct. It is using the HT filters in preference. The &quot;warnings&quot; you see about are actually in another bit of code. It tries to connect first based on the pin names of the Intervideo filters, but finds those pins dont exist (because we're using the HT filters), so then tries the HT pin names. The messages make the log look a little untidy, but its not a problem worth working about. I'll clean this up before the next public release.

Based on the picture, I suggest you go back to the offical drivers. This looks like some of component GUID dont match up.

The only true error I get is the one when it tries to the set the audio device pin format. But I've got sound, and the file sizes are on target. Getting a high quality recording at half the bit rate that a typical MPEG2 recording has to record.
