ffplay is not showing up even though reStream is capable of capturing a video with ffmpeg

[Tim Holzschuh]

I tried using reStream, but it didn't really work:
First of all I couldn't use "10.11.99.1" for some reason but had to change everything to "192.168.178.47".

Then the ssh-copy-id for some reason didn't work. It didn't report any errors, but the remarkable didn't obtain a ~/.ssh/authorized_keys files.
After I manually added my ssh key it worked though (I accidentally first used a ed25519 key, maybe that was why?).

Anyhow. While using the -o option to record my screen works fine, just plainly using the script won't open an ffplay player.

The script printed:

Any thoughts?

I used ffmpeg 4.3.1 on NixOS.
ffplay itself is also working (it plays the video I captured with -o just fine)

Okay, for my part, I succeed creating a new certificate without any password and it works like a charm ! Thanks for the job !

This is still a bug since one should be using stuff like ssh-agent to hold the key in memory instead of repeatedly asking the user for the passphrase of the key.
