USB camera not listing

[anishmenon]

How we can read the External camera now it only reads the front and back camera see an app that reads all external cameras

Specify a LocalVideoTrackOptions.deviceId when creating a LocalVideoTrack.

DeviceIds can be found through Camera2Enumerator.deviceNames if Camera2 is supported on the device, or Camera1Enumerator.deviceNames if Camera2 isn't supported (check with Camera2Enumerator.isSupported(context)).

can u revert an example

var videoTrackCaptureDefaults: LocalVideoTrackOptions = LocalVideoTrackOptions()

i can see below name on other app debugging
'/dev/video63'

var videoTrackCaptureDefaults: LocalVideoTrackOptions = LocalVideoTrackOptions(deviceId = "/dev/video63")

but its not working

Again, get the device name through the process I mentioned in the previous comment.

Camera1Enumerator Camera2Enumerator

are basically throw front camera and back cameras it won't list USB / external

[anishmenon]

https://github.com/libuvc/libuvc this library will be able to throw all connected USB video devices

Hmm I think this may be out of scope currently, if the phone doesn't support discovering the USB camera through Camera2.

You can use libuvc/other 3rd party libraries to create your own org.webrtc.VideoCapturer and VideoTrack to support this feature.

Closing as not planned.
