Video encoding on Rock Pi 4B

mannam · October 22, 2019, 7:04pm

Hi,

I’m trying to encode USB camera video to H264 using mpphenc and gst-launch running on latest debian stretch build version
https://dl.radxa.com/rockpi4/images/debian/rockpi4-debian-stretch-desktop-arm64-20190730_2022-gpt.img.gz

I’m getting the following errors when I run my gst-launch pipeline too.

Found there is a fix for it in video driver 6 months ago,

Did this update make it to this debian build? If not any guidance on building and installing driver from source will be very helpful.

Thanks!

I think the fix is in the kernel. Rockchip has the fix in the stable-4.4 branch but the ROCK Pi 4 current kernel is based on the release-4.4. We have rebased to the latest Rockchip stable-4.4 kernel, some functions are still in the porting(mainly the raspberry pi display) but I think we can release a package for you to test first.

You can download the kernel package from:

https://dl.radxa.com/users/dev/

Install and reboot, check the test_enc again.

Thanks for new packages and instructions.

I installed them with dpkg -i linux-* and rebooted. It still boots from old kernel.

Is there a way to change boot order? I couldn’t find grub menu.

edit your /boot/extlinux/extlinux.conf and check if you have linux-image-4.4.179-6-rockchip entry, make sure linux-image-4.4.179-6-rockchip entry is at the first place.

It does have latest kernel listed but it doesn’t boot from it.

I have the exact same problem. What does one need to do to boot into the new kernel?
