1. rm /usr/lib/camera/com.qti.sensormodule.imx214_3.bin
2. cp /usr/share/modalai/chi-cdk/imx214-flip/com.qti.sensormodule.imx214_flip_3.bin /usr/lib/camera

1. Download the file com.qti.sensor.imx214_flip.so and place it in /usr/lib/camera on VOXL2
2. Download the file com.qti.sensormodule.imx214_flip_3.bin and place it in /usr/lib/camera on VOXL2
3. Remove the file /usr/lib/camera/com.qti.sensormodule.imx214_3.bin on VOXL2. If this file does not exist on VOXL2, please let me know -- it will require a different procedure.

Is a VOXL2 camera driver with 180deg rotation in the works?
The alternative for us would be physically modify the structure on our fleet of aircrafts - which is not something i am very keen on.

With SDK1.0, voxl-camera-server sends OMX pre-encoded H265 streams to voxl-streamer. The encoding done by voxl-camera-server is way more efficient (keeps the VOXL2 nice and cool) than the encoding done by voxl-streamer in SDK0.9.5. @Zachary-Lowell-0 explained that pre-encoded streams cannot be rotated by voxl-streamer, which i have verified as well.

Maybe I missed something, but I don't understand why @Zachary-Lowell-0 's suggestion would not work. Do you want to use both : rotated and not rotated images or something like that? If you just want the rotated encoded image, then it seems what Zachary said should work for you.

I am using the encoded stream so this approach does not work for me.

Can the rotation be achieved through the use of the rotated IMX214 driver similar to how it was done here? (@Alex-Kushleyev )

Would you have a functional com.qti.sensor.imx214_rot180.so?

@hmlow all you need to do is change the pipe you are subscribing to in voxl-streamer. You cannot rotate an encoded stream, but you can to the raw stream. Change the pipe in the voxl-streamer.conf file to point towards hires_small_color and make sure the rotation parameter is filled and the next time you run voxl-streamer, the frame will have been rotated properly.

Was searching around for a solution and i stumbled upon this.

I downloaded libmmcamera_imx214_rot180.so and renamed it into com.qti.sensor.imx214_rot180.so but voxl-camera-server wasnt't happy. (i guess it is due to the new implementation on the SDK-1.0 )

Would you have a functional com.qti.sensor.imx214_rot180.so?
That would solve all my problems.

Thanks!

Is it still possible to rotate in software if the video is OMX hardware encoded now?

Can the rotation be done in voxl-camera-server?

I noticed there is a "flip" parameter here:
