Default to cv2

[g7gpr]

Default to cv2 whilst investigating gstreamer performance.

[adalava]

It's good! I maintain a RMS container (ubuntu 22 based, mostly x86_64) and I had to force it to use cv2 while I find some time to investigate why it's not working even after installing all packages. There's still something preventing it to work well in some cases.

Hi guys, Is it not working for you at all, just hanging at the start of capture? I had the same issue and I fixed it my installing the latest version of gstreamer through conda in a conda environment. See the README file in the dev branch for full details.

Sometimes stops partway through capturing. Operators report short timelapse videos.

Is this on the Pi or a linux PC?

Denis, in my case it hangs right at the start of capture, no frames are received. Reproduced it on 2 different x86_64 machines (total of 6 cameras/RMS instances). The RMS container is Ubuntu 22.04 LTS image based with stock packages. I'll check whatever is better: update gstreamer packages from non standard repository or go though upgrading it to Ubuntu 24. It will take some time since I need to validate on both x86_64 and aarch64.

In case it helps someone, here's the list of gstreamer installed packages and versions:

I'm running a Linux PC on ubuntu 22.04 with gstreamer without any issues after installing the new version of gstreamer. I had the exact same issue with 1.20. After purging the install, I used 1.22.3 and all issues went away.

I created these new installation instructions: https://github.com/CroatianMeteorNetwork/RMS/tree/dev?tab=readme-ov-file#software No need to compile opencv anymore using that script, the conda version works just fine as long as gstreamer is used for capture.

Shows that all the videos are the expected length.

For the Pi4 platform, which is the main focus for me, is it recommended to upgrade gstreamer to 1.22.x, and retest on a known troublesome system?

[dvida]

I haven't tested on the Pi, but give it a go. As the Pis don't have things installed though conda, you may have to install gstreamer system-wide.

[g7gpr]

OK. On it.
