xuesichao commented 2 years ago

Hi @dathacky. There are two types of device: Device or VideoTransformDevice. The original camera is of Device type. The VideoTransformDevice is a device that applies processing to another device. So background blur function is actually a VideoTransformDevice. It applies background blur processing to the original devices.

When you switch the background blur filter between different CPU utilization, the actual logic here is JS SDK is switching between different devices.

The reason you observe the black video tile is that the video tile is not removed during the switching, but the camera stream is stopped for a while.

Hi, sorry for the inconvenience and thank you for reporting this. We will look into this and respond to this ticket. Thank you.

dathacky commented 2 years ago

@xuesichao @hekmatba Thank you, hope it gets fixed soon

dathacky commented 2 years ago

@hekmatba Hi, hope you are still interested in this issue

dathacky commented 2 years ago

@hekmatba @ltrung I hope this ticket is not forgotten

michhyun1 commented 2 years ago

@dathacky I think this is not a bug, but rather a side effect of selecting a different device. @xuesichao mentioned the behavior above, which is expected when switching between devices.

mrnav90 commented 2 years ago

@michhyun1 So this is not a bug, can we create a fake track ( stream ) when device selecting? Before, we're already used Jitsi Library and also happen that so my team create a fake track replace when device selecting..

michhyun1 commented 2 years ago

@mrnav90 what is the purpose of a fake stream? When you switch from one device to another device, we need to turn off one device and then select and turn on the next device. Currently, that includes switching between a regular video device and a VideoTransformDevice that is applying a video filter to a regular video device.
