Hello everyone,

I am trying to play 4K videos with VLC but vlc fails. Command line : cvlc vide_name.mp4 Result - Output : 

[a57106e0] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

I am using Compute Module 4 and Bullseye

Best regards, Chayma.

What video type? HEVC/H265, H264, AV1? The only one that is expected to work is H265 (being the only one with h/w accel).

The video Type is H264 I got this Info from VLC in my desktop mediainfo

Then I'm not surprised it doesn't work. Pi 4 doesn't have the CPU power to do that and its h/w H264 decode is only good to HD (its basically the same block that was in a Pi 1). This falls into the realm of "can't fix".

So teh video should be scaled to lower resolution or we can encode it to H265 so vlc can play it ? What do you think ?

Thank you for your help!

jc-kynesim commented 10 months ago

H265 4k should generally work as long as you are using DRM output (windowed output will fail), HD H264 will also work.

Thank you for this valuable Information.
