Rather than doing a timer based frame capture, this change modifies the implementation to rely on callbacks from webrtc capturer whenever a new frame is received via pipewire. Corresponding WebRTC change is here: https://webrtc-review.googlesource.com/c/src/+/291080 Bug: chromium:1291247 Change-Id: Ia00edc110dfe40918e1ad0862472f70d7c849c9f Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/4188923 Reviewed-by: Lambros Lambrou <lambroslambrou@chromium.org> Commit-Queue: Salman Malik <salmanmalik@chromium.org> Cr-Commit-Position: refs/heads/main@{#1099800}
