Octoprint + mjpg-streamer ffmpeg error

Troubleshooting
1

Good night,

I have an onl rasp pi2 and i decided to try octoprint, i made a fresh installation and everything seems to be working except the camera. I did a bit of reasearch and i found that for the camera to work i will also need to install mjpg-streamer, the problem is that with octoprint installed i have an error installing ffmpeg.

I leave the error i am getting in the extra details.

Thank you

Truthfully…the absolute best way to run octoprint is in a docker container…I have it running like a boss on my AtomicPI running my Anet A8 3d printer (of which I need to print more)

This way it’s a self contained instance, and doesn’t rely upon the OS’s installed packages…if it can’t pull ffmpeg due some sort of dependency failure…the docker package will already have it installed

Heck I even installed octoprint on an old cellphone I had, used the USB-OTG port to run it (it was on a easythreed X1) using octo4a

Yes, there is a known challenge for ffmpeg. This might be a workaround for time being. The following packages have been kept back: ffmpeg - #28 by Joulinar

Thank you for the feedback

My linux capabilities are still very low, i tried docker recently but i had a lot of problems running nextcloud when i tried to change the database location.

I will give it another try with octoprint.

Thanks again
