Re : Own software to use a camera

[Malsoaz James]

Thank you for your help, I will have a look at that.

Have you any document about the function present in this library ? I mean information on the arguments used in each function, list of the functions and their goal, ...

For example, for v4l2_open, there is a char * = /dev/video0 and then a flag certainly O_RDWR, ...

And now this library is integrated in the current v4l-dvb branch
http://linuxtv.org/hg/v4l-dvb
You will find the lib in v4l2-apps/lib/libv4l..
All this work was made by Hans de Goede.

Cheers,
Thierry

Not yet... I plan to do something for my own understanding.

These calls shall have the same behavior than the v4l2 driver ones. So you can refer to the v4l2 API.
