Quickblox Android sample video chat - Distorted video stream

In case somebody experiences the same issue (and for a better visibility) I'll also post this question and its answer here (Original thread):

I have successfully installed and ran the sample video chat app on several different Android devices. Only on my Samsung Tab A running Android 5.0.2 the incoming video streams are showing up distorted after about 20-30 seconds:

I have gone through the logs an figured out that a "decoder format changed" message is logged simultaneously with the video getting messed up:

Has anybody experienced a similar issue and can provide me with some ideas on how to resolve this issue?

Solution

  • After tinkering with the settings I found a workaround for this issue. By deactivating the hardware acceleration on affected devices, the distorted video stopped to appearing during the video chat.

    QBRTCMediaConfig.setVideoHWAcceleration(false);
