Own software to use a camera

Own software to use a camera

[Malsoaz James]

Hello,
I'm currently working with a camera and try to use it thanks to video
for linux. I have good basics in programming but not with this library
and I want to make a simple software to take photos and videos with the
camera.
I have looked the help
for v4l2 but it seems there is a lot of things to do to use the camera
: open device, init, choose format, standard, ...

Can someone
help me by telling me the different steps I have to follow to take a
picture with the camera and save it in a current format as jpeg ? Then
I will add some function to take picture automaticaly, and to use video.

I
have already made a part of the program : opening the device, checking
the capabilities, but I'm quite lost because of the numbers of
possibilities offer by v4l2. I don't really know what to do and when to
do it...

Some existing software such as motion seems interesting
for me but there is too many options, so I prefer do my own software
with the function I need.

I hope there is someone here to help me
Thanks, have a nice day
James

James,

I suspect you may benefit from using the new v4l-library. It should
help simplify the conversion of whatever format the camera supports
into whichever format your application desires. The current
development branch of the library is located here:
http://linuxtv.org/hg/~tmerle/v4l2-library/

Regards,

David Ellingsworth

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
