Emby Android TV client always transcodes AV1 videos on MT9669 TV

[qizcc 3]

When using the Emby Android TV client on my TV to play AV1 videos, it always triggers server transcoding.

My TV’s CPU is MT9669, which is capable of AV1 hardware decoding (other clients on the same TV can play AV1 directly).

When installing the same client on an Android phone, it can play AV1 videos directly without transcoding.

Could it be that the TV client does not report AV1 support for the MT9669 when communicating its device capabilities to the server?

Hi, did you explore the stats feature in the video player to learn why it was transcoding?

Hi.  Can you try searching for our standard android app (Just "Emby" on Amazon and "Emby for Android on Google) on the same device's app store and see how that compares?

Thanks.

您好，您是否查看过视频播放器中的统计信息功能，以了解它为何会进行转码？

Hi,

Here are the playback stats. The transcoding reason is: Unsupported video

To make sure the issue is not related to a specific file, I tested multiple different AV1 videos with different MKV files and audio configurations.

The result was always the same: the Android TV client triggered video transcoding.

However, when playing the exact same files with Emby for Android, they are played via Direct Play without any transcoding.

This makes me suspect that the Android TV client may not be reporting AV1 support correctly for my device (MT9669), even though the hardware itself supports AV1 decoding.

Hi,

Yes, I already tested the standard Android app (Emby for Android) on the same TV device.

Using the exact same AV1 files and the same server, the standard Android app is able to Direct Play them without any transcoding.

You may want to send a log showing the error from the Android TV client to ebr

I went into the user management settings on the server and disabled all options related to audio/video transcoding and container format changes for my user.

After doing this, the same AV1 videos that previously triggered transcoding now play via Direct Play on the Android TV client.

For reference, I have extracted the relevant portion of the Emby server logs (not the complete log) showing this behavior.

Did you also send the ATV log?  I believe ebr can see what the TV passes for codec support from that log.

Hi.  This is expected.  The TV app is not looking for the AV1 codec.  The standard app does support it though.

thanks,The TV app does support AV1 decoding. I just disabled audio and video transcoding in the user profile settings, and now it works fine.

For me, that’s enough—my goal was simply to get the TV to decode AV1, and that’s now solved. Really appreciate your help
