Have you tried Meshenger 4.2.4? And have you tried changing the resolution via the menu (small gear icon in the left top corner) during a call?

Yeah, I don't know if it's my phone's camera, but I changed it to capture and cast, and it's blurry, even though I set resolution first

Then it is hard to say why WebRTC cannot or won't capture a higher quality video stream.

I switched to h264 encoding and the sharpness improved a lot, but the latency issues remained

hm, where did you switch it to h264?

I customized the encoderFactory, which uses vp8 by default, and I changed it to h264

Please share you changes. Maybe it is enough to expose the vp8 and h264 setting. Then I could add those as settings.

Nice. Have you tried to just disable VP8? https://github.com/meshenger-app/meshenger-android/blob/master/app/src/main/kotlin/d/d/meshenger/call/RTCCall.kt#L531 (with enabled hardware accelaration)

Yes, it didn't work when I just set vp8 to false, I used a custom coding factory that worked, and now my picture quality and fluency have improved when I coded with h264 and reduced the frame rate, but there is a key problem that sometimes my picture gets blurry for a moment due to the webrtc strategy

Thank you. I will give it a try.

@CWTakiku can you try a fresh install of 48756d0 on both phones?

Btw., the video codec limit to h264 makes by phone unable to connect. I am still investigating.

I looked at your commit history, it seems that you did not set up a custom factory, just configured the default acceleration factory, I will provide my coding factory class for you to see

@CWTakiku thank you, I will give it a try. I did not commit my custom factory, since it broke the call feature for me.

I tried the code with only isSupportedH264 returning true (like in your screenshot), but now the phones cannot establish a connection.

Aside from that, the picture quality with the current master is pretty good (HD).

What you need is that both the receiver and the sender need to set up the custom encoder to establish the connection, and how does your image quality improve

hm, I had the same software on both devices. Here is the source code: https://github.com/meshenger-app/meshenger-android/tree/h264

I will do an intermediate release with enabled hardware decoding by default (it wasn't working right before). Then let's do more testing.

Ok, theoretically it's OK, but it's been proven to work on my side and has been used in my own projects
