Hi Lou,

I'm sorry but the project is not actively maintained from my side
anymore for quite some time. Good luck in fixing the issue yourself.

Best,

-Nico

I am trying to build avcap 0.1.9 under ubuntu 18.04. After downloading
I do

.install
make

The install procedure has no fatal errors. However, make would not run
because:

|"V4L2_ConnectorManager.cpp:29:10: fatal error: linux/videodev.h: No
such file or directory"|
I tried to fix this by executing

$ sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h

and then ran

$ make clean; make

which produced the following errors:

V4L1_ConnectorManager.cpp:63:24: error: aggregate 'avcap::V4L1_ConnectorManager::query()::video_channel vc' has incomplete type and cannot be defined
struct video_channel vc;
