How to send constant resolution 640x480

[Genesis]

Hi, I'm having trouble defining a video resolution in a video conferencing project. I need to always send 640x480 to SDK, I specify this in the getusermedia method. after reading the information in the forums, I realized that getusermedia will not give me what I want, since webrts itself determines the optimal resolution depending on the speed of the Internet and the CPU. My question is:

1) is it possible to specify a permission constant?
2) if yes, how to implement it?

What browser are you using (assuming firefox)?

You can view how to use getUserMedia here https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia

You're looking for something like this:

getUserMedia({
  audio: true,
  video: {
    width: { min: 1024, ideal: 1280, max: 1920 },
    height: { min: 576, ideal: 720, max: 1080 }
  }
})

The terms you are looking for are "decimating frames" or "downscaling".

Chrome/Edge/Safari decimates frames just fine, firefox is the only major browser that doesn't at the moment. 

Please add a comment here if offering support for firefox in your application https://bugzilla.mozilla.org/show_bug.cgi?id=1286945

no, it doesn't work in my case. talk about it https://groups.google.com/g/discuss-webrtc/c/u6XlfwUEAo8/m/pqd3Nsk5FQAJ. Are there any examples of using these methods?

Not sure if you have seen the examples from samples - - https://github.com/webrtc/samples/blob/9428dd8d6f38dd2d7810e2e644d6ff0958d3b3f7/src/content/capture/video-contenthint/js/main.js#L52
