Did you attach a network dump?

no

gofaster commented 1 year ago

This seems related to the presence of a tuning file that worked with prior versions of libcamera. Without specifying the tuning file, mediamtx starts. So, not a mediamtx issue.

gofaster commented 1 year ago

This format of the tuning file will be deprecated soon! in the log was not exactly true. Newest libcamera choked on it. Converted with `convert_tuning.py' and mediamtx/rpicamera working as expected.

aler9 commented 1 year ago

@gofaster i took into consideration the idea of embedding libcamera into the server in order to avoid these never ending compatibility issues caused by sudden and backward-incompatible updates.

The problem is that libcamera is currently not embeddable, since it depends on tuning files placed somewhere in /usr. Anyway, I'll do another try in the future.
