Question / Help Can't Capture Dazzle DVC 100

[baegolas]

I recently updated from Windows 7 to Windows 8, and since then I haven't been able to stream using my capture card, and after testing a few things out I'm having some weird results. Window capture works on all windows I've tried, but when I capture the window with the video from my capture card, the portion of the window showing the actual capture shows up just white (prior to some messing around, it showed up as black, and also as a single frame from the capture card that never changed). I also found that monitor capture shows up black, as does video capture device set to the capture card.

Some things about my hardware and settings:

I'm using a laptop with an Nvidia Geforce GT 540M video card, and I've set it so that OBS, the game capture window in amarec, and the global settings are all set to use the Nvidia card. I'm also running 64 bit windows as well as 64 bit OBS, though I don't think that should be relevant.

Also, here's the log for my most recent stream preview:

I actually am totally baffled - it says that you're using YUY2 for your video, but that it couldn't connect to the output pin. I'm not sure what to suggest -- have you tried changing around all the settings for it in the source properties? Does it have any other output formats (where it says "use output format")?

I know that probably isn't the best suggestion I could make, but I actually am not sure why it's not working and I'm hoping maybe changing the settings (output format, or even resolution/FPS) might change something.

I tried messing around with the settings for the both the video capture device method, and the window capturing AmaRecTV method, no luck. However, I did find that (for some reason) if I don't have AmaRecTV open, I can capture the video from the capture device source, but I'm unable to get audio from the capture card this way (I was using AmaRecTV as a sort of work around to not capturing audio with OBS). This way, I also get another output format called I420, which was selected by default. Hopefully this sheds some light on what exactly is going on. Here's a log with the working video capture, but no working audio:

You can't open the device directly in both AmarecTV and OBS at the same time, this is a limitation of DirectShow drivers in general. However, AmarecTV comes with a DirectShow passthrough (Amarec Live), which you can add as a video capture device in OBS. Be aware that it only works in the 32-bit version of OBS, though.

It is possible to get audio when using the Dazzle directly in OBS, please search the forums for other Dazzle topics, as I have already explained this a bunch of times.

 

[baegolas]

I've tried using Amarec Live on 32 bit OBS, no luck. The only other thing I saw that looked like it might be helpful was a link to something called "Crossbar Thing" but the link to the download was dead.

 

[paibox]

"No luck"? What do you mean no luck, didn't you get the sound to play in Amarec? And yes, the server Crossbar Thing is on is currently down due to an ISP fuckup, I really wasn't expecting that to happen, sorry.

 

[baegolas]

Amarec has no trouble getting sound, but I can only capture video in OBS with Amarec closed, regardless of which capture method I use or whether or not I'm using Amarec live. The no audio issue only comes up when I have Amarec closed, and I'm using the video capture device source in OBS. It sounds like the crossbar thing should solve that problem (hopefully).

 

[paibox]

It would, but... if you have sound in AmarecTV, then you can just pass that through to OBS using Amarec Live. Just select "Amarec Video Capture" for the Device when adding a video capture source and "Amarec Audio Capture" for the Audio Input Device (on the right side of the properties dialog) in OBS.

Both of the solutions I posted in the other thread work equally fine, they're just two different solutions. I unfortunately still don't know when my ISP will fix their screwup so that I can get my server back online, but the Crossbar Thing alternative is just if you really don't feel like using AmarecTV.

 

[baegolas]

I'm not opposed to using Amarec, but I have no way of capturing it with OBS. Even though Amarec is getting the video and audio onto my computer, OBS won't capture the video. So as of now, if I use Amarec, I get sound but no video in OBS, but without Amarec, I get video with no sound, but since there's a known fix for the no Amarec method, I'll probably give that a try. If it helps at all, here's a screenshot of my desktop while trying to capture the Amarec window. As you can see, it captures the window itself, but not the video from the capture card. http://i.imgur.com/fcDpUF8.png

 

[paibox]

I am not telling you to capture the Amarec window, dude. AmarecTV comes with a Directshow passthrough called Amarec Live. The installer for it is in your AmarecTV folder and is called live_setup231a.exe. If you install this, AmareTV gives you one virtual device for video and one for audio that will duplicate whatever you see/hear in AmarecTV in another application that is capable of using video capture devices, such as OBS/VirtualDub/whichever.

 

[baegolas]

I got it working! I didn't see the virtual device showing up because I'd accidentally been using the 64 bit version of OBS. Thanks for all the help, I really appreciate it.

If anyone else finds this thread and is having a similar issue, here's all the settings and stuff I changed. I have AmaRecTV setup more or less normally, but with live enabled, and I also set the format's ffc option to YUY2 (I have no clue what this means, but it wasn't capturing correctly in OBS otherwise). In 32 bit OBS, a video capture device called AmaRec Video Capture should show up, and that will work correctly, or at least it did for me. Hopefully this helps someone else who has a similar problem.

 

[Sajuuk]

Hi, I tried following these exact same stages but OBS isn't picking up the AmaRec output properly. I set it to the YUY2 option for the video stream and did all the linking so the audio/video would pass through to OBS, but OBS just picks up a very jerky output and stuttering sound. It's rather aggrieving to say the least. Any assistance in this matter is appreciated.

EDIT: If anyone has trouble with the Dazzle DVC100 in OBS, rollback to OBS 0.50b which strangely seems to work as it should be. Latest updates are somehow introducing bugs that cause audio but no video with a Dazzle. It fixed the issue for me at least.

 

[dodgepong]

I do not recommend rolling back OBS versions to solve the problem. If there's an issue, it's best to get the issue fixed rather than rolling back and ignoring the problem. But 0.50 is an extremely old version that I would never recommend anyone use anyway.
