Vega Open Beta Bug Reports

Description

Seen the first time by end of August and identified as a Kepler issue second week of September.
Randomly, every 1/10 to 1/5, a playback of a content (Live or VoD) stops after 2 to 3 seconds of playback. When the issue appears, the enduser can see first a blackscreen of 1 second and then an infinite red spinner is displayed. The error message from our application is “pipeline error decode”. When this issue appears the enduser can only exit the playback to start it again.

App Name: Canal+
App Link on Amazon Appstore Canal+ 4.6.2

Steps to reproduce

  1. Be sure your WiFI connection is stable with enough bandwidth to playback UHD.

  2. Start our Application with connection/login

  3. Start a batch of playback with our application (around 15 tests): Live 4K or SVOD 4K. contents to reproduce issue: Live channels: Canal+ BoxOffice UHD, Canal+ UHD HDR, .2 UHD and for SVOD contents: AppleTV+ contents.

The current behavior

  1. Randomly, enduser can observed an infinite red spinner 3 seconds after the playback of the video. The low level Webplay (MSE/EME) stops the playback. Our application catchs the error ““pipeline error decode”“.

  2. Enduser can do a back to the previous screen of the App and runs the playback again.

The expected behavior

No black screen and infinite spinner should be observed.

Is this a blocker? Do you have any workarounds?

This issue is blocker for the launch of our App on Kepler device because it happens too frequently.

workaround: do a back with the RCU to the previous screen of the App and start the playback again.
