Smooth video playback on rpi 1
« on: November 03, 2024, 06:57:04 PM »
Hello, we have few devices on picore 14 and vlc was used to display videos/images. The problem is that on rpi 1 it's very slow and stuttering, any suggestions ?

Wasn't that a 700 Mhz armv6 cpu? That's equivalent to something like a Pentium 2. Would your videos play fine on a P2? (those cpus were not able to play DVDs, for reference).
The only barriers that can stop you are the ones you create yourself.

Is vlc compiled with hw acceleration.
So not only use framebuffer and uses the gpu and av instructions on the cpu.

And you could install omxplayer that support the gpu, to accelerate the picture and video.

I played around with hardware acceleration on an RPi0 a while back - it was quite slow.

The vlc in the repo should use hw acceleration if available, those vlc instructions referenced above are using the old closed source omx and neon - I'm not sure neon is available on RPi0 and RPi1.

You could try ffplay:
Code: [Select]
ffplay -i /mnt/mmcblk0p2/media/video/jellyfish-3-mbps-hd-h264.mkv [I think this would use hw acceleration]
or
ffplay -codec:v h264_v4l2m2m -i /mnt/mmcblk0p2/media/video/jellyfish-3-mbps-hd-h264.mkv

Note that you may need dtoverlay=vc4-kms-v3d and dtoverlay=rpivid-v4l2, check that /dev/video* exist.

Thank you, do you have insights how to install omxplayer on picore 14?
