I tried to log media typesubtype of frames which ManyCam delivers to the application.

Issues with web page layout probably go here, while Firefox user interface issues belong in the Firefox product.

You may use a prebuilt binaries for Apple sample, but you also have to disable signature check for Kexts to have it work.

Entirely black video screen in Facebook call (attached file FacebookFF49.png).

For ManyCam Virtual Webcam webcam on OS X 10.12 and Firefox 49.0.1 (only appeared in the webcam list for resolutions 640x480 and 1280x720).

For Apple Sample webcam on OS X 10.9.5 and Firefox 49.0.1 (it only appeared in the webcam list for 1280x720 resolution).

Apple Sample webcam shows video with time counter (see attached FacebookFFbefore49.png).

It was shown under the same conditions in previous FF version.

Camera section in test.webrtc.org report shows this (the output is from Firefox).

For ManyCam Virtual Webcam webcam on OS X 10.11 and Firefox 38.0.5.

For Apple Sample webcam on OS X 10.9.5 and Firefox 37.0.2 (it seems to only really support 640x480 resolution).

I tried to debug from the side of CoreMedia IO plugin (LibraryCoreMediaIOPlug-InsDALManyCamVideoDeviceCMIO.plugin or Sample.plugin) - and nothing wrong can be seen from inside of plugin - all frames are passed to the Firefox application correctly.

The workflow doesnt seem to differ from any other application where the webcam works - Chrome, QuickTime or previous version of Firefox.

There was a similar issue under Chrome in the past: but they fixed it in new versions.

Only test.webrtc.org reports were slightly different.

Manycam Virtual Webcam Failed Install Python 2

See for details (you need to install python 2.7 to run mozreg).

Run the command mozregression --good48 then copy here the final pushlog from the repository mozilla-inbound.

Chrome fixed this in Chrome 53 which should be the stable version soon if it isnt already.

Blocks: 1180725 Status: UNCONFIRMED NEW Rank: 23 Ever confirmed: true Flags: needinfo(kd2) Priority: -- P2 Summary: Mac OS X: FF from version 49 stopped to work with webcams based on CoreMedia IO plugin Webcams based on CoreMedia IO plugin dont work since FF switch to AVFoundation.

Dmitry can you confirm that ManyCam is working with Chrome 55, e.g.

Chrome Canary which is at 56 now.

Manycam Virtual Webcam Failed Code And See

If it works the simplest way forward might be to compare our AVFoundation capturer with the one found in the webrtc.org code and see if we can figure out what it does differently to accept the frames.

Flags: needinfo(kd2).

And since the problem is reproducible on Apple Sample too, you may take its sources as a base -.

It has some minor compilation issues on latest OS X and Xcode, but is still usable.

When we query the capability, every capability supports the format UYUV.

That sounds like a bug in ManyCam to me which they should fix.

Awesome if we can make Firefox code more resilient for such broken behavior, but I dont think that should high priority.
