AudioVideo | Android音视频相关的Demo

I am trying to capture video/Audio frames from CMSampleBuffer but completely failing to obtain a proper video recording.

Expected Output: A Video file in .mp4 format that has both audio(from the mic) and video frames.

Current Output: An Empty Directory/A video file without audio.

Crashes on Run : Media type of sample buffer must match receiver's media type ("soun")

I tried almost everything available online to troubleshoot this. I have a deadline coming and I just pulling my hair trying to figure out what exactly is going on. Any help/pointers are highly appreciated.

Below is the source.

I've a React JS App that uses the Chime SDK. I've literally followed the explanation here and i can successfully hold a meeting with two attendees. My issue is the behaviour when one of the participants leaves the meeting.

My references are:

• This link states "To stop the meeting session, call meetingSession.audioVideo.stop()."
• This link states "You start tearing down a session by calling stop on the AudioVideoFacade .... this.audioVideo.stop();"

When i run meetingSession.audioVideo.stop() the attendee appears to leave the meeting (their audio and video stops) - which makes sense. My issues are:

1. Locally, the attendee's audio and video are still showing as active in the browser. How do i release them? I've tried setting the meetingSession object to null but it didn't work
2. If i then run meetingSession.audioVideo.start() the attendee rejoins the meeting but with a new Tile ID. Why isn't the same Tile ID used if the Attendee is the same?

Overall it seems my issues all relate to being unclear how to leave a meeting and a) be removed from the meeting roster and b) release objects locally in the browser.

Thanks in advance

I have a page with several tags. Whenever I play the audio in Chrome (Desktop, macOS), it starts immediately, while in Safari (13.1, macOS) it waits for some time before starting playing (the weird thing is that it waits longer if they are several audio tags on the page).

I thought that the problem was with the "preload" attribute not set, so I've set it to "auto" according to the docs]1, but it didn't change a thing.

I don't want to use a 3rd party library to keep as as simple as possible.

How can I remove this delay? And why is it longer the more audio tags I have on the page?

I am working on a video conferencing app that leverages Amazon Chime. I have followed the npm page of Amazon Chime SDK JS and managed to get the server response and initialized the meetingSession. However, the problem is when I try to get an array of audio output devices, it is an array of length zero on Safari whereas in browsers like Chrome and Firefox, it works just fine, and I get an array of non zero length. How do I solve this?

Here is what I have coded so far:
