Hi Matthew,
When you try to run voxl-logger with the hires camera it should have given the following error message:
voxl:/$ voxl-logger --cam hires --samples 1
connected to ch 0 cam server: /run/mpa/hires/
ERROR only support RAW8, RAW16, and FLOAT32 images right now
got NV21 instead
The reason these are the only formats currently supported is because it uses opencv to save/load images. OpenCV is quick enough for black and white images, but simply too slow to be practical for large color images.
As an experiment I just made a new branch of voxl-mpa-tools with a slow but functional switch-case for the NV21 images produced by the hires camera. This will work for saving one or two images, but won't be able to keep up with a steady 30fps stream.
Here is the code if you want to try:
https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-mpa-tools/-/commit/633adfdaf8162548d5df4218243a32e06d2ea7b1
Migrating voxl-logger to use a faster image compression library and/or hardware acceleration is in the pipeline but I can't promise a release date for that I'm afraid.
I hope this helps,
James
