I'd like to modify the SOURCE video stream from FFMPEG, NOT the transform done in .octoprint. I have my video working fine in octoprint, but the image is flipped for use in home assistant. I can't figure out how to flip the image/stream in home assistant so i figure the other angle to attack is fix the source.

and because there's always that guy:
no, i can’t re-orient the camera
no, i’m not turning the printer upside down
no, i’m not turning my head to view it

You can flip or rotate the image from the streamer.
Which image are you using?
The regular one or the new camera stack?

[Charlie_Powell]

On the old camera stack OctoPi image (which it looks like you have), you can edit the parameters passed to mjpg streamer using octopi.txt:

How can I change mjpg-streamer parameters on OctoPi?

You can change that via the config file octopi.txt. You can access it in two ways: directly from the Pi: You can find the file at /boot/octopi.txt, just open it with your favorite text editor (e.g. nano), adjust it and then reboot your Pi (since the changes will only take effect at boot time) from another computer: You can plug the OctoPi SD card into a card reader of your choice and plug that into another computer and open the card there. The file can then be found directly in the root dire…

Available mjpg-streamer configuration options

The following configuration options can be supplied to MJPG Streamer on start to modify certain camera settings. To change any of these options in OctoPi, edit the relevant sections in octopi.txt as described here. USB webcams (input_uvc.so) input_uvc.so comes bundled with MJPG Streamer. See also the documentation for the recommended MJPG Streamer fork (bundled with OctoPi) for additional options not listed here. -d <device>: The video device to use, e.g. -d /dev/video0 -r <resolution>: …

Some things to note:

• Not all cameras support all of the options, so you might not be able to flip it at source
• The cameras are not streamed by ffmpeg, so don't look at that

It is mentioned on this systeminfo bundle page, that explains all about it and where to find it and what to do with it. There's a link to the page.

old stack.
octoprint is fine, it's rotated within there, i want to adjust the original feed

[athlonduke]

i've tried editing the file in boot and it either doesnt work or gives a configuration error. its the original pi camera so i think it has support to do whatever and it's not a random USB one.

Please share exactly what you put in the file, so we can see if it's right.

This caused error:
camera="input_raspi.so"
camera_raspi_options="-rot 180"
causes error:
Webcam stream not loaded
It might not be configured correctly or require authentication. You can change the URL of the stream under "Settings" > "Classic Webcam" > "Stream URL". If you don't have a webcam you can also just disable webcam support there.

This didnt change anything:
camera_raspi_options="-rot 180"

yes i rebooted after changes

[athlonduke]

ahhhh

first one is
camera="input_raspi.so"
camera_raspi_options="-rot 180"

[athlonduke]

so i did notice this too:
No longer available under OctoPi 1.0.0, use input_uvc.so for the Raspicam there

camera="input_uvc.so"
camera_raspi_options="-rot 180"

that doesnt work either, causes this:

@athlonduke

This caused error:
camera="input_raspi.so"

Make sure you're reading the configuration instructions correctly. The only options available for camera="..." are auto, raspi or usb.

In this case you want to have camera="raspi".

@athlonduke

No longer available under OctoPi 1.0.0, use input_uvc.so for the Raspicam there

Looking at your systeminfo bundle shows that you are running OctoPi 0.18. So this comment does not apply to you. Using camera_raspi_options is correct. Don't use the USB mode.

[athlonduke]

appreciate the help. changing camera to just "raspi" yields same error as above
