Changing frameRate breaks video track/stream from getUserMedia on LG devices

Issue description
Steps to reproduce the problem:
1. Prepare LG V10 as test device
2. call getUserMedia with constraints.video.frameRate or applyConstraints({frameRate: <value>}) to existing local media stream
3. attach media stream to <video> element
What is the expected behavior?
Playback of local camera pictures on the <video> element
What went wrong?
Broken / weird picture is rendered which seems to be representing some part of the page / html content
* Note: attaching the media stream to peerConnection, remote client will always see nothing (it seems nothing is transferred between the clients for the video track, watching webrtc-internals)
Did this work before? Yes 64
Does this work in other browsers? N/A
Chrome version: 65 Channel: beta
OS Version: 7.0
Flash Version:
This problem started to happen on this specific device (LG V10) from Chrome 65 (or 64) - pretty sure it had been working w/o problem in the older versions.

ultravisitor@: Is the problem specific to the LG V10 or is it reproducible on other devices? Can you provide a jsfiddle or similar test for easier reproduction?

@guidou: Thanks for your comment. So far the problem seems to be specific the LG V10. I might be able to try some other handsets including LG V20 tomorrow. (not so many, maybe just one or two more devices) jsfiddle: https://jsfiddle.net/dw0wy473/19 You'll see blank / white area on the video element (like attached), if tested with the LG device

Tested the issue using #65.0.3325.109 and #67.0.3375.0 on Android LG G5, 6.0.l and able to reproduce the issue by navigating to above jsfiddle. Observed video is not streaming. Observing the same behavior since M51. Untriaged for further inputs. Please navigate to below link for log's and video-- go/chrome-androidlogs/823114 Thanks!!

@sandeepkumars Thanks Did you have chance to test on M64? I think you won't see/repro the problem using that version. > Observing the same behavior since M51.

Either myself or braveyao@ should check if we can find a LG V10 or LG G5 and check if in this case the camera is opened successfully and delivers frames or not.

Should this be bumped to M69?

FYI, still seeing the issues using Canary M69 on the reported device - any updates would be greatly appreciated. Also, my comment on #8 was not right (The browser I tested with success was actually M51 or something). Can't test anymore but I guess the issue was also reproducible on M64 and probably earlier versions as @sandeepkumars noted.

Tested on the following device: LG G5, LG-H860 Rev 1.0, Android 7.0 Tested using the following Chrome versions: 55.0.2883.91 -> No repro 66.0.3359.158 (stable) -> No repro 69.0.3447.0 (canary) -> No repro The video from the camera displayed correctly in the video element in all three cases. Not sure if the difference is the Android version or hardware revision compared to #6. sandeepkumars@ could you try on a few other LG devices to see on which ones it repros? |
