Hi, I'm trying to set up the Mixed Reality Capture Tools to be able to record a demo with the Oculus Quest. I've managed to calibrate a USB camera and uploaded the config onto the device under my app's files/ directory and I have OBS set up with the 'Oculus MRC' fg/bg sources as documented. I can connect to the device via OBS once I start my application but when I do I seem to just get one frame grabbed by OBS and the app framerate suddenly drops down to about one frame per second, with no visible updates in OBS beyond the first frame.I wonder if anyone else had any luck using the latest Mixed Reality Capture tools (Oculus_MRC_Tools_2.0/1.41.0_RC1, OBS 23.2.1, Unity Integration Asset 1.40) and can maybe give some hints for what I might need to do to get it working?

This video was uploaded today: https://www.youtube.com/watch?v=p1c8D_l0upI Hope its of help in some way.

Thanks, it's a good overview of the technology and the setup process, though I think, afaikt, I did everything as described.One thing that caused me some trouble for a while was that I was using OBS 24.x.x to start with and it turns out that the current plugin binaries are tied to the OBS 23.x.x ABI which wasn't immediately obvious.I'll maybe take another stab and see if I have any luck.

I was struggling for a while with 24.x not seeing the Oculus MRC camera. Seems like the official docs should clearly state the version needed.

Well until developpers integrated Oculus MRC, then I think its best, as a content creator for me to wait until the Oculus Link update is out in November then we can integrate with Steam as LIV is still working on wireless solutions and Mixcast also don't have wireless for now..Oculus Demo also showed Bestsaber on quest mrc, so not sure...I'll ask Oculus list of titles available, and see if we can share it as I can't find online.Thx for the replies, clarified all points.

Rib , i might be able to help but am stuck at the last hurdle, am not able to get my obs to connect the mrc.xml files.1.Do you save the camera file to mrc.xml after doing a chroma or after finish calibration only during camera calibration(so before clicking chroma)? 1b.I assume we can close the camera calibration window after saving the mrc.xml file?2. To transfer mrc.xml file to quest, you put {youroculusdeveloper name}.{youroculusappnane}.files or .{youroculususername}.{beatsaber}.files. (example);3. When I open OBS after putting all the plugging folders in the root, I click the + in the source, I see OculusMrcSource, do you see that too or do you see Oculus MRC? 3b. The video capture source I assume was same as used during the camera calibration process, we don't use the screen (if left open) of the chroma from the canera calibration window from previous steps, correct? As mentioned I closed that window after saving the mrc.xml file as we are told to do chroma from obs, not calibration in previous steps, is that correct?4, after i apply the filters pad/crop and change the relative settings, my fg abd bg dont change blue or green, so am stuck there,4c, when i click connect after changing the ip in the OculusMrcSources, nothing happens.I tried a lot of variations and would really appreciate your help on this. Please let me know if you able reply here or wish a Skype or messenger chat, or discord.Thx Laz

Yeah in the OC6 session they mention they are "working with" Beat Saber, Dead And buried 2 and super hot

I tried copying my camera xml config to the com.beatgames.beatsaber/files location and it doesnt connect with OBS Studio and i ran a port scanner on there and also my own built app and can not even see the port listening and when running the below adb command for beatsaber I can clearly see its not implemented yet as it doesnt even try to start the camera capture in the app.

When i check to see if its running on my own app I get:

./adb logcat -s OVRPlugin

About Mixed Reality Capture Tools, only one program of skybox vr can be recognized in obs. Other applications cannot be recognized. How should I operate?

Today I tried for scene composition of MixedRealityCapture in OBS. I have been using a 1920 * 1080 resolution monitor for it. In OBS the output I get from sources like foreground, background and video capture I wasn't able to resize them without getting the output cropped/cut. On a 4K monitor, I am getting output as expected. Am I missing any option to resize the sources without getting the output cropped ?
