GoCoder Android SDK - play live stream issue: An exception occurred attempting to start the decoder

Hi all,

I’ve recently made some example Android code which records from the camera and streams the video from the Android device up to the Wowza Streaming Cloud where I can login and view the live stream.

I’m now attempted to play the live stream within another Android app, following the code example here: https://www.wowza.com/docs/how-to-play-a-live-stream-with-wowza-gocoder-sdk-for-android

However, I am getting an error ‘An exception occurred attempting to start the decoder’. If anyone can shed any light, I would very much appreciate it.

I’ll post the code sample below along with logs. I’ve removed my credentials from the sample, but I’m using the same credentials (Host Address, Stream name etc) as the code that streams to the Wowza cloud.

Thanks in advance.

Thanks @Mike Smales, Let me see if I can get some insight from our SDK team. I appreciate your communication with me and your patience.

Hello @Mike Smales

Please try calling WOWZStatusCallback and you’re player view in a click event to see if this resolves your issue:

public void buttonClicked(View view) {
    WOWZStatusCallback statusCallback = new StatusCallback();
    mStreamPlayerView.play(mStreamPlayerConfig, statusCallback);
}

Regards,

JasonT

Thank you for responses @Jason Tuchler and @Rose Power-Wowza Community Manager

Unfortunately, moving the WOWZStatusCallback into a click event had little effect.

I was however able to get it working by swapping devices… for whatever reason the error occurs on a Nexus 7 (6.0.1) but it works fine and as intended on the other test device I have here, a Moto Z3 (8.1.0).

Thank you for sharing that with us Mike.
