Bug 210173 – [iOS] webrtc/h265.html is consistently timing out

• Status: NEW
• Component: WebRTC

[Ryan Haddad]

webrtc/h265.html is consistently timing out on iOS / iPadOS simulator bots

The test has been timing out since it was added with "Add initial support for WebRTC HEVC" in https://trac.webkit.org/changeset/259452

Skipped the test on iOS in https://trac.webkit.org/changeset/259702/webkit

[youenn fablet]

stderr:
(RTCVideoEncoderH265.mm:505): Failed to set data rate limit(h265_vps_sps_pps_tracker.cc:81): No PPS with id 0 received
(h265_vps_sps_pps_tracker.cc:81): No PPS with id 0 received
(video_receive_stream.cc:721): No decodable frame in 200 ms, requesting keyframe.

So something is not working properly on the simulator or iOS.
