Issue descriptionExample URL: ConnectUsCom.com, appear.in, github WebRTC demo Steps to reproduce the problem: 1. Create a WebRTC call using Chrome on Android 2. 3. What is the expected behavior? Video is very dark and poor quality What went wrong? I am having a quality problem using Video with a WebRTC application on my Android phone. The phone is a Samsung S5 (SM-G900V) running Android Vs 6.0.1. The Chrome browser is vs 51. I am using the ConnectUs webrtc application. The video is very dark and seems of a rather poor quality. The problem is the video created on the Android; the far end video being diplayed on the phone is fine. Other Android phones seem to be able to run the same app with no problems. I can run it on my desktop Chrome and on IOS phones with no problem. I thought it must be a phone hardware problem, but native type apps can display the video just fine, but using WebRTC on Chrome on Android is consistently poor. I have tried with Skype, Vidyo, and the Appear.in SDK and they work normally. I have also tried 3 WebRTC apps with the Chrome on Android browser and they are all dark and poor. They are Appear.in (non SDK), ConnectUsCom.com, github WebRTC demo. Did this work before? N/A Is it a problem with Flash or HTML5? N/A Does this work in other browsers? N/A Chrome version: 51 Channel: n/a OS Version: 6.0.1 Flash Version:

I can confirm the same issue happens on my Galaxy S5. getUserMedia video is very dark. For example simple demo at gives dark video: https://webrtc.github.io/samples/src/content/getusermedia/gum/ On same phone, built in camera app does not have the problem. Same webrtc demo shows fine video from a PC. This did not happen until relatively recently. Probably 1 month ago video was fine. Android upgrade to 6.0.1 happened in that timeframe, which may or may not be related. Phone is Verizon Galaxy S5, not rooted. Running Android 6.0.1 and Chrome 51.0.2704.81.

This really seems to be an issue with Chrome for Android rather than the Samsung phone. I have the same issue using an Asus tablet.

Sorry to play hot potato with you, Chris, but can you find an appropriate owner? Niklas/Tommi, is this something that Brave could look into?

I guess the camera app controls the auto exposure in a different way than Chrome, since Chrome tries to achieve a specific FPS (30) while the camera app has a different criteria when taking a photo. cward42@ Could you paste a screenshot of the camera app i video mode since it's more comparable than the photo mode (does not have to achieve 30fps)? magjed@ is there anything we can do here? I guess we are limited by the getUserMedia constraints used and if none are provided, a default set of params?

It looks like the problem is that the Chrome Android code selects a fixed 30 fps range instead of choosing an interval e.g. 15-30 fps. A fixed fps effectively disables auto exposure. Sami - can you update the camera code in Chrome to prefer fps intervals with as low lower bound as possible, same as in webrtc: https://cs.chromium.org/chromium/src/third_party/webrtc/api/android/java/src/org/webrtc/CameraEnumerationAndroid.java?rcl=0&l=178. The Camera1 fps selection code in Chrome is here: https://cs.chromium.org/chromium/src/media/capture/video/android/java/src/org/chromium/media/VideoCaptureCamera.java?rcl=0&l=153 and the Camera2 fps selection code in Chrome is here: https://cs.chromium.org/chromium/src/media/capture/video/android/java/src/org/chromium/media/VideoCaptureCamera2.java?rcl=0&l=299

What is the status of this. I would expect something like this to get fixed. Google is working very hard on WebRTC and this doesn't leave a very good impression. I first posted this in July and it is still an issue. I have both an Asus tablet and a Samsung phone. Both have this same problem. It looks like you have identified the problem, but when is a fix coming?

I'm sorry, and I agree we dropped the ball on this one. Two CL:s were actually uploaded to fix this issue 3 months ago: https://codereview.chromium.org/2354923002/ and https://codereview.chromium.org/2357863002/ but never got landed due to long review discussions. The CL:s are still working and are relatively simple. mcasas@ - can we please land those CL:s so we can finally close this issue? sakal@ is now on vacation so I'm reassigning to you.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/072357660ad4bc52bcfb4c3c4bb4ad71730b4367 commit 072357660ad4bc52bcfb4c3c4bb4ad71730b4367 Author: sakal <sakal@chromium.org> Date: Thu Jan 05 21:20:01 2017 Update FPS selection logic in VideoCaptureCamera to select a wider FPS range. The code fixes the bug referenced by the bug field. If requested fps is 15 and the camera supports fps ranges 0 - 30, 10 - 20, 14 - 16 and 15 - 15. Previously, we would choose 15 - 15 fps. This is bad because it doesn't leave the camera room to adjust based on the lighting conditions. Heuristic copied from WebRTC chooses the 10 - 20 fps range instead.
