hi
i've got hikmicro mini2plus USB-C camera module. my host is PI4B 4Gb bookworm - all packages upgraded
it works on phones using hik apps
works on windows using
>ffmpeg -f dshow -video_size 256x192 -i video="UVC Camera" -c:v libx264 -pix_fmt yuv420p
i can get raw frame
v4l2-ctl --device=/dev/video0 --set-fmt-video=width=256,height=192,pixelformat=YUYV --stream-to=frame-yuyv.mjpg --stream-count=1 --verbose --stream-mmap —stream-skip=1
and convert it to jpg
but result on linux is not what you expect from thermal camera - its a frame with 5 images together - like 5 different streams in one frame. i get that one is thermal data others different other channels.
here is my data
i get errors like
ffmpeg -f v4l2 -video_size 256x192 -i /dev/video0 -vframes 1 -q:v 2 -f image2 output1.jpg -hide_banner -loglevel trace

im desperate already, thiking to bu y another thermo module. but i cant check all on the market buying everything.
