I’ve a fresh install of Anthias on Raspberrypi5 and tried Powerpoint generated Video to upload as asset.

Anthias says: “Video codec ‘h264’ is not hardware-decoded on this device. Supported: hevc.”

`ffmpeg -i ‘video.mp4’ -c:v libx265 -preset medium -crf 28 -tag:v hvc1 -c:a aac -b:a 192k -movflags +faststart ‘video.hevc.mp4’`

Could you please help which steps I have to take now?

Newbie Questions:  
How can I apply the ffmpeg command? (is ffmpeg already installed?)

Where can I find the uploaded mp4 asset?

Thanks, Martin

Yeah, this is a new and intentional change.

Basically, most Pis will drop frames when playing videos aren’t using hardware acceleration. To make matters worse, Pi 4 only support h264 and Pi 5 only support h265.

To answer your question, you need to run this on _your desktop_. The Pi will not be able to do this without choking.

You might consider using Handbrake (handbrake.ft) instead if you want a user interface.
