Max size format

Max size format

[Gabriel Duarte]

Hello all!
I've built an app to get the max size of my cameras! I got two capture
devices, and simple webcam, with max size 640x480 and a TV capture card, max
size 744x480. When I query my webcam, at /dev/video0, it returns the right
size, but my TV card returns a weird size, like this:


*gabriel@bourbaki:~/Desktop$ ./camera_size /dev/video0*
*raw pixfmt: YUYV 640x480*
*pixfmt: RGB3 640x480*
*gabriel@bourbaki:~/Desktop$ ./camera_size /dev/video1*
*raw pixfmt: BGR3 48x32*
*pixfmt: RGB3 48x32*
*
*
I'll attach my code and if someone find out what is going wrong, I'd be very
glad!

Thank you all!

Usually, you should take 720x480 (D1.NTSC) or 720x576 (D1.PAL) or 640x480
(VGA) size from a TV capture card.

I know, but the camera driver returns me 744x480. The image size is not a
problem to, because there is post processing to it;
