@rokgregoric
After disable and re-enable the user’s video, our stream resolution will gradually adapt to the best.
Btw, the resolution will changed as your network bend-witch changed.

resolution can change … but not the aspect ratio … this makes the video to change zoom if you fill the aspect ratio

@rokgregoric
Would you minder to tell us the detail of usage?
1.Are you using the rawdata or canvas?
2.how to subscribe the user’s video?

user.getVideoCanvas()?.subscribe(with: view, andAspectMode: .panAndScan)

Hi @rokgregoric ,
Can’t download your sample zip file. And the sample code paste is for pan and scan mode. That will not show the black line as your picture shown, will cut some video and show full screen.
Please confirm again.
Thanks

here is the sample using a different transfer service: WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free - hope that works for you.

Changing the aspect mode to pan and scan - DOESN’T fix the issue - when the aspect ratio / resolution changes the zoom of the video changes, and users can notice that:

Still not fixed in v1.5.0

@jackie.chen This happens only when using an externalVideoSourceDelegate and
session.sessionPreset = .vga640x480

When setting the preset to:
session.sessionPreset = .hd1280x720
the aspect ratio is correct.

Hi @rokgregoric ,
Thanks for your important information. Will push our team to handle this issue.

@jackie.chen please check Black video using v1.5.0 + externalVideoSourceDelegate. The two issues are related.
