Powerpoint video: Video codec 'h264' is not hardware-decoded on this device. Supported: hevc

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.
