Question / Help DVCamera + AV out + EasyCap capture card

[Zirgotv]

Good day OBS forum

I have been using/testing with Wirecast before but have had problems with the CPU usage on my laptop while using the program for recording to disc/live streaming. So I was eager to try out another program. So far the CPU seems to be used much better with the OBS software so I would like to use it for my productions.

I am on a laptop using win7 64bit. Before I have used, with success the capture card and camera in Wirecast. So I started to use OBS, added a scene and wanted to add a capture source. The program detects the card and detects the two resolution settings/ FPS options that the card delivers, one being a PAL setting at 25fps and the other a NTSC setting at 30fps. I have been using before the PAL setting so I setup the program to use that, plus configured it to use the PAL_B setting (same that I have used in Wirecast), but I can see that it doesn't capture the cam properly, adding scanlines and distorting the image as well as adding some jitter in the bottom. I try to use some other configurations except PAL_B but with the result that the program hangs up and I am forced to close/restart it.

What am I missing here? Is there some more setting that I need to be aware of that I didn't need to think about when I was using Wirecast?

If I can get this problem out of the way I think I may well be using this program instead of Wirecast due to its more friendly CPU usage.

hm, I'm not entirely sure.. it doesn't necessarily work with every device at the moment. could you go into the bug forums (where you probably should have posted this - but all is well!) and use the directshow diagnostic app here - viewtopic.php?f=6&t=59 ?

 

[Zirgotv]

Understood. I'll run the diagnostics application as soon as I can, and post the results. Sorry if this post was made in the wrong area since I wasn't sure if it was something that I had set up the program wrong or if it was an error from the programs part. I'll post the results from the app in this post to keep it in one thread.

The results from the diagnostics application shows the following. I am trying to use the "SMI Grabber Device" in
mode 720x576, fps: 25

Device: 1.3M WebCam
type: YUY2, usingFourCC: false, res: 640x480 - 640x480, fps: 15-30
type: YUY2, usingFourCC: false, res: 320x240 - 320x240, fps: 15-30
type: YUY2, usingFourCC: false, res: 1280x800 - 1280x800, fps: 7.5-7.5
type: YUY2, usingFourCC: false, res: 1280x1024 - 1280x1024, fps: 7.5-7.5

Device: SMI Grabber Device
type: UYVY, usingFourCC: false, res: 720x576 - 720x576, fps: 25-25
type: UYVY, usingFourCC: false, res: 720x480 - 720x480, fps: 29.97-29.97


I am using the latest available OBS version.

could you post a screenshot or vod of the output issue you're getting?

 

[Zirgotv]

Ok, I have posted a video where I record the stream output from OBS, using the SMI Grabber Device in full screen on the canvas. Here is the link for it http://youtu.be/2sBaYqwDr4I . You can see that it does capture the contents from the card, it just distorts it and splits the image up, sort of like old air wave tv:s in the old days where you had to adjust the antenna just right to get the image "clear". I move the camera in the movie, and the "image" changes accordingly. The jitter in the bottom is there regardless and is not part of anything coming from the camera. So other OBS setting are in this recording the 720x576 resolution set for the card, the settings for the program is the same resolution and fps set to 25. I have also tried this with aero enabled/disabled, but no dice. If there is any more options that I can venture on, let me know.

I remember that, on other programs I've used Easycap with in the past, it always needed to be deinterlaced to work properly. Don't know how much that helps in this situation, but I thought I'd offer my experience.

drop by the irc channel #obsproject on quakenet sometime and I can take a closer look directly, if I'm there at the time. http://webchat.quakenet.org/?channels=obsproject if you want to try webchat -- I'll usually be marked as asleep/away if I'm not around.
