TroubleShoot HTML5 and WebRTC Streaming in VideoWhisper

These refer to issue that may occur after VideoWhisper solution was configured correctly, tested and running.
If you don’t have it installed, yet get a plan for a turnkey solution, in example for HTML5 Videochat .

 

  •  Video pixelation, low quality:

    Check selected streaming resolution & bitrate and also real streaming bitrate measurements (available in HTML5 Videochat app  ).
    WebRTC also adapts quality depending on available connection and network conditions for UDP. Measure your connection and also try RTMP TCP broadcasting with OBS or other encoders, as mentioned below.

  • Broadcaster streaming interruptions, frequent errors, slow website while streaming:

    Some broadcasters may experience issues due to their internet connection speed, location (very far from streaming server). Having a lower connection requires adjusting maximum streaming bitrate, so it doesn’t consume all available bandwidth.

    Do a speed test from broadcasting location to a location near streaming server.
    1. Go to https://www.speedtest.net .
    2. Change Server and search for a server in Beauharnois (North America).
    3. Press GO to start measurement.
    3. Get measurement link from top left icon and share with our staff.
    Broadcaster upload connection needs to handle video + audio stream and also other interactions and web requests.

  •  Connection to sever is high and streaming quality is low and with interruptions, although configured high bitrate in settings:

    Check live bitrate stats in HTML5 Videochat app. If connection bitrate is high and live streaming bitrate is lower than configured, issue could be related to network conditions and WebRTC protocol streaming over UDP.
    For higher quality and reliability, broadcasting is possible using a RTMP TCP app like OBS for desktop or GoCoder mobile, directly to streaming server without depending on web browser. RTMP stream is delivered to site users as HTML5 HLS.

  • Broadcaster getting browser streaming failure error, Retry message, permission errors, camera not available in list:

    Make sure you are loading site over HTTPS (required to publish camera).
    Test with a different browser: Chrome, Firefox, Brave, Safari.
    Try the Brave browser (Chrome privacy focused fork).

  • Intermittent connection issues associated with slow site or intermittent 503 web errors.
    Web hosting resources may be underpowered for site complexity and load.
    Try reducing complexity (by removing plugins) and resource load per request or upgrade to a higher plan from HTML5 WebRTC Relay Hosting .
  • Broadcasting stream not connecting or disconnects:
    Check if bitrate (video + audio) is within plan hosting limits. Trying to broadcast higher bitrate will result in automated stream rejection and short cooldown while all connection attempts are rejected.
    See Client Upload (kbps) for your plan at HTML5 WebRTC Relay Hosting and configure lower.

Clarifications:

  • NR = Not Recommended. Red5 can be used for recording/archiving but often produced skipped frames in our tests.
  • Plesk = Managed web hosting on VPS is based on Plesk for 10 domains.
  • CPanel = Managed web hosting with a CPanel account. Higher plans allow multiple domains.
  • WHM CPanel = Host unlimited domains, cpanel accounts.
