MediaElement playbackRate not working

Web App Development
1

Hi everyone.
We have seen an issue changing the playback rate in a video element.
We have a test app for testing different video players. In this case, we using shaka player
and we are changing playbackRate property but the speed is not changed.
In the case we launch the same app running in a web server through the navigator app, playbackRate change is working correctly.

Is there any known issue about this? Is there any solution or workaround?

Thanks in advance,
Julián

We cannot check 3rd party player issues. You can use the playbackRate with the native player, but the sound is not supported in this case. Therefore, it is not appropriate to use it to control the playback speed. Thank you.

I’m curious as to why it is like that?

We wrap a simple shell app with an HTML redirect similar to this:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>TV Demo</title>
    <meta http-equiv="refresh" content="0;url=https://example.com/">
  </head>
  <body>
    <h1>Loading…</h1>
  </body>
</html>

When doing so, this is technically a Website that is navigated within the shell of an LG application installed on the TV directly. The same Website navigated within the LG TV Web browser works and we can use playbackrate on our HTML Video Element without any issues.

In counterpart, while isolated in the application, changing playbackrate does nothing. What is the reason to prevent us from using this feature on an HTML Video element?

That’s the TV app spec. If there are any updates, we will let you know via our website. Thank you.
