Fire TV - Google DAI ad playback errors on CMAF streams

Thanks for your report!

We can't start email conversation over [email protected]. That's a one way channel I'm afraid. Can you please provide us with the IMA assetKey for the live test stream?

Another step would be to create a bug report right after you have reproduced the failure, upload it here or send it by email using a subject in the format "Issue #1072". Please also update this issue to indicate you’ve done this.

If this is specific to a Fire TV device, it would probably be more difficult for us to help. Please provide us with a bug report in this case so we can see the entire log output and the exact device model.

When I play the live DAI stream from the assetKey or the HLS stream directly I see it fail for reasons of HTPP 404. Can you please check whether you see the same issues when playing the stream? If this is the case I think this isn't a player problem but the HLS playlist contains URIs that are not available.

I'd recommend using our demo app for testing, because then we both use the same app and can rule out problems in an app. You can edit/add a live HLS DAI entry in the media.exolist.json and then run the demo app. When I do this I see the 404s pasted below.

The error you reported above is about a failed LoadTask:

androidx.media3.exoplayer.ExoPlaybackException: Source error ExoPlayerImplInternal: Playback error LoadTask: Unexpected exception loading stream

This potentially matches to the 404 exceptions I see when playing the stream you sent us:
