What are the manifest and license server URIs?

The manifest URI has be send via email

What configuration are you using? What is the output of player.getConfiguration()?

Sent via email

What did you do?

  1. Point an LG container app at https://shaka-player-demo.appspot.com/
  2. Click “Custom content” to navigate to the view that allows you to add your own content
  3. Click the “+” button at the bottom right hand corner of the window to add your content, add a name for this custom content and paste the manifest URI sent via email
  4. Play the content out and observe that the content stalls at around the 2:30 mark

NB The manifest URI point to an unencrypted DASH stream that has server side ads stitched in at certain point (also detailed in the email)

What did you expect to happen?
The content continues to play without issue through the 2:30 mark and beyond

What actually happened?

The player remains in a playing state but the content enters an indefinite stalling state

We have attempted to recover the stall in the following ways:

  • Enable the stallDetection with Threshold set to 0 and 2. A stall was report around the expected time of 2:30 into the stream. Neither setup resolved the stall although the player state changed from being stalled in the Playing state to being stalled in the Seeking state.
  • Remove B-frames from the Ad-content
  • Checked for gaps in the buffer (no gaps were reported)

We can't directly support or debug on WebOS. This is currently considered a "community-supported" platform because we don't have the devices or test infrastructure set up for WebOS.

We have purchased a WebOS device, and we intend to build out infrastructure to support it, but we have no timeline for that yet. Other issues are currently higher priority.

@joeyparrish, May I ask what model of TV with WebOS you have bought?

I think it was WebOS three-point-something, but I can't recall. It is still in a box in the office. It was something I intended to spend time on before the pandemic hit, and I haven't been able to get back to it since.

It'd be great to find out the specifics, we've found that neither the WebOS version nor age of the device to be a very reliable way of determining a device's capabilities and therefore the likelihood of being able to reproduce the issue
