High CPU usage with built in player on Emby app android

[Grimx00 0]

When I play video on Emby's built in player I experience significantly higher cpu usage and battery drain compared to using an external player (VLC). As you can see in the screen shots Emby uses almost double the cpu utilization and battery drain (485mAh vs 251mAh) while also making my phone very hot. My theory is that Emby forcing software decoding for h.264 for some reason. I think it happens for h.265 as well but to a lesser degree.

Emby Android 3.4.74

Emby Windows server 4.8.11.0

Subtitles and Audio?  Graphic subs are perhpas being converted by Emby, while VLC can play them drectly.  Audio can run into a similar situation.

ASS subtitles and AAC or AC3 audio. ASS subtitles have been a pain but that's what all anime comes with.

ass subs should be fine.  AC3 audio may often need converting and that uses up CPU clicks.  Check the playback details to see if AC3 is allowed to go direct with your setup.

That is surprising given that it is direct playing and rendering with hardware decoding (MediaCodec). If you turn off the subtitles how does it compare?

Turning off subtitles definitely lowers the cpu usage.
