no element "v4l2h264enc" error in arm-* containers

[DX37]

Hello there.

I'm using arm-chromium container and Raspberry Pi example docker-compose config. Today I encountered error, which I don't understand why happens. It appears neko or gstreamer can't find v4l2h264enc element or even omxh264enc element, which I tried to use myself. I exec'ed with shell into container and I think gst packages installed properly, but it's still doesn't work. I tried to build containers with build script, but it didn't help.

There's log.txt from container.

Trying to rebuild these containers, starting with arm-base. Excuse me, forgot to rebuild it too.

Did that fix issue? arm- images are not built automatically, as #102 is not resolved yet. They can be outdated. And also make sure, you did not forget --privileged: true and you don't have installed docker in rootless mode.

No, it didn't. Same issue. Docker runs as service under root, and I starting built containers with docker-compose config for Raspberry Pi, which have this privileged option. What else I can do?

I just took Raspberry Pi 3 Model B+, built arm images and started using unchanged example configuration. It works out of the box, did not find any problems on the way.

Can you chek if you have working kernel side support? Do you use Raspberry Pi 4?

I can test my Raspberry Pi 4 (4GB) tomorrow if it works 🙃

Yes, I can. Because I have Raspberry Pi 4 too and I wouldn't create issue if I didn't have one.

And yes, I have kernel side support, out of the box:

@DX37 could you please try with latest arm images?

Unfortunately I can't - switched to x86 server last summer ¯\_(⌐■_■)_/¯

Well. Thats also a valid solution to this issue.
