Undefined symbol in obs-kinect-freenect.so

[hollowshiroyuki]

Hi !

I can't get my Kinect 360 to work on Archlinux.

OBS crashes with this message in the logs :

obs: symbol lookup error: ./obs-kinect-freenect.so: undefined symbol: freenect_convert_packed_to_16bit

The libfreenect seems to work there is those messages in the logs too :

info: [obs-kinect] [freenect] freenect info: [Stream 80] Negotiated packet size 1920

I'm running OBS from the command line in the plugin directory so I don't have to use LD_LIBRARY_PATH for now.

Thanks for your assistance !

Hi,

This is because the lib currently need a custom version of libfreenect which adds the missing function.

You can find it here: https://github.com/SirLynix/libfreenect

With same build instructions as the default lib.
You can either install it on your system or put it next to obs-kinect-freenect.so (should work without touching LD_LIBRARY_PATH)
