MicroPython Forum (Archive)

Hi,

I would like to play a video on a pyboard, that is, connect a display to it and a loudspeaker
and then play an MP4 or something similar.
A S070BWS45HG-DC84 with KD070HC700BT-1024600 HDMI interface is available as a display.
Is that even possible (system resources ...), what additional hardware do I need?

greetings
johup

It depends how big the video is (i.e. resolution) but unfortunately almost certainly not possible with a pyboard. Ideally you need a hardware video decoder to do the video decompression.

I'm not aware of any MicroPython boards with HDMI output either.

Your best bet is probably a Raspberry Pi.

but the Raspian on the Pi gives me 20s boot time, that I dont want. Is there a bare metal
port of micro python to Raspberry Pi?

Yes......... https://github.com/boochow/micropython-raspberrypi

But also I think it would take a fair bit of work to get it to the point where you need it.

I will do that. Do you know anyone else (in the forum...) that tried this out?

Yes it gets discussed occasionally.

The author of the port has also participated in some of the discussions: search.php?author_id=3510&sr=posts
