Hello Laurant,
sorry I am flooding a bit here, but now I reached a point where I am
really stuck.
In the get_fmt_pad I set the following format
*format = mt9p031->format;
that is defined as
mt9p031->format.code = V4L2_MBUS_FMT_SGRBG10_1X10;
mt9p031->format.width = MT9P031_MAX_WIDTH;
mt9p031->format.height = MT9P031_MAX_HEIGHT;
mt9p031->format.field = V4L2_FIELD_NONE;
mt9p031->format.colorspace = V4L2_COLORSPACE_SRGB;
I found the different formats in /include/linux/v4l2-mediabus.h. I
have 12 data bit channels, but there is no enum for that (like
V4L2_MBUS_FMT_SGRBG10_1X12).
I am the first guy needing a 12 bit-bus?
Second thing is, the yavta app now gets stuck while dequeuing a buffer.
strace ./yavta -f SGRBG10 -s 2592x1944 -n 4 --capture=4 --skip 3 -F /dev/video2
...
ioctl(3, VIDIOC_QBUF, 0xbec111cc) = 0
ioctl(3, VIDIOC_QBUF, 0xbec111cc) = 0
ioctl(3, VIDIOC_QBUF, 0xbec111cc) = 0
ioctl(3, VIDIOC_QBUF, 0xbec111cc) = 0
ioctl(3, VIDIOC_STREAMON, 0xbec11154) = 0
ioctl(3, VIDIOC_DQBUF
strace gets stuck in mid of this line.
cheers,
Bastian
