[weller0]

Configuration

Wolvic version: v1.5.1
Wolvic build ID: 220

Hardware: PICO 4
Quest 2 also has this issue.

Steps to Reproduce

1.Use ue pixel-streaming(https://docs.unrealengine.com/5.2/en-US/experimental-pixel-streaming-features/). I have a packaged version().
2.After decompressing Windows. rar, run the PC side service

3.Enter the Wolvic browser and enter the PC address, for example:https://192.268.1.10

4.Entering VR mode

Current Behavior

Currently in black screen state

Expected Behavior

It can display normally

Possible Solution

By checking the settings, it was found that the encoding option is empty, while there is an encoder in the PICO browser

Is there any way to test that in a linux machine?

The backtrace looks weird because it does correspond to the loading of the native code, i.e., Gecko engine in this case, but in your report you're already playing a video in Wolvic. Are you sure that's the right backtrace?

Just to confirm that is not a limitation in the underlying Android system, are you able to reproduce it on the Pico browser or the Meta browser?

It may be that this process crashes causing no screen to appear

I don't have a Linux environment to test here(I only have WSL2). But it is stably reproducing.
PICO optimizes many logs, so we use Quest to test and capture logs

Thanks for the information. We're superbusy now preparing a new release, but will take a quick look after that to check what's going on
