Issue Description

Instagram to join the interactive live button is grayed out and can't click to join and the anchor can't invite viewers to join the interactive live video.

STEPS TO REPRODUCE: (please be specific)

1. The auxiliary machine opens the instagram and opens the interactive live video.

2. The test machine enters the live video

3. Observe the interactive live button change

REPRODUCE RATE:

10 times out of 10 tries

EXPECTED RESULTS:

Join the interactive live button will always be on, you can enter the interactive live video at any time.

OBSERVED RESULTS:

After entering the live room, the button will be automatically grayed out after three seconds, click to enter the interactive live video

PIXEL: normal

ANALYSIS:

Facebook reply is as follows:

This was caused by the lack of support for OMX.hisi hardware codec in MediaCodecVideoDecoder,which is a open source lib mainly supported by Google Chrome team.I have been reached out by the Huawei team who are working on OMX.hisi hardware codec.And I have told them to reach out to WebRTC team to add the support of OMX.hisi. After that we will merge the change to our apps.But we need your support on test at that time.Closing this task here.Will continue the conversation with Huawei hardware codec team.

I found that some resolution like "640*480, 320*240" will crash，and they aspect ratio are "4:3"。
