v4l2src: queries framerate interval based on max frame size instead of current frame size
Our camera has a different max framerate depending on the current frame size. Specially when having a reduced height we can increase the frame rate by a lot (HW limitations of how many lines we can read out).
However when gstreamer negotiates the CAPS it seems to be using always the max frame size instead of the current one. Which results in a max framerate much lower than what the driver actually supports.
Fx at 1024x1024 (max frame size) we can do 28.292 fps
root@qt5022:~# w=1024; h=1024; f=RGB3; v4l2-ctl -d /dev/qtec/video0 --list-framesizes ${f} --list-frameintervals width=${w},height=${h},pixelformat=${f}
ioctl: VIDIOC_ENUM_FRAMESIZES
Size: Stepwise 4x4 - 1024x1024 with step 4/4
ioctl: VIDIOC_ENUM_FRAMEINTERVALS
Interval: Continuous 0.035s - 25.054s (0.040-28.292 fps)And with 1024x100 we can do 280.867 fps
root@qt5022:~# w=1024; h=100; f=RGB3; v4l2-ctl -d /dev/qtec/video0 --list-framesizes ${f} --list-frameintervals width=${w},height=${h},pixelformat=${f}

ioctl: VIDIOC_ENUM_FRAMEINTERVALS
Interval: Continuous 0.004s - 25.054s (0.040-280.867 fps)However I get a non-negotiated error in gstreamer with fx 1024x100@100fps

Freeing pipeline ...We can see in the driver that gstreamer is calling ENUM_FRAME_INTERVALS with the max frame width and height.
The problem seems to be in the gst_pad_query_caps which is using the max frame size instead of the required one: video/x-raw, format=(string)RGB, width=(int)[ 4, 1024, 4 ], height=(int)[ 4, 1024, 4 ], pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)[ 85714285/2147483647, 500000/17673 ];
