Summary
page.screencast.start({ path })with a.mp4path records AV1 video with the built-in Chromium encoder (Page.startScreenRecording), without ffmpeg and without screencast frames.crVideoRecorder.tsand uses its own CDP session, because Chromium rejects recording and JPEG screencast in one session.Recording mp4 video is only supported in Chromium. Other extensions keep the WebM recording.Fixes #43999
