When recording, the frame size dynamically changes if there is a webrtc bitrate increase/decrease. Is there a way to force the frame size of the recording to stay the same?

What you mean by frame size? Resolution?
If you open one of the webm recordings and that person had a bandwidth or other fluctuation during the recording, the size of the video frame will change. This used to also show on some of the examples, that users video box would increase or decrease in size, I think it is to stop the video being overly pixelated. The new call application always keeps the video window sizes at one size. However, the video recording size when using the recording example changes in size.
For our use case in need the recording video sizes to keep a single size.
As WebRTC changes resolution dynamically to provide better quality, your recorded video using INDIVIDUAL recording will also change its resolution.
If you want the same resolution always you have 3 options:
- Use COMPOSED recording
- Process INDIVIDUAL recording after session is recorded
- Try to tweak the browser to send always the same resolution regardless bandwidth used (https://www.chromestatus.com/feature/5135353876840448). But it just landed in Chrome 83.
