Hi,
Is it possible to add new pixel format to videodev2.h file?
#define V4L2_PIX_FMT_MJ2C v4l2_fourcc('M','J','2','C') /* Morgan JPEG 2000*/
I have developed a V4L2 driver for the board with hardware JPEG2000 codec
(ADV202 chip). This driver uses that pixel format.
I think JPEG 2000 is very perspective codec and it will be good if V4L2 will
support it.
Short description of the device is here:

Thanks,
Vladimir.

Please, send patches and other e-mails related to drivers development to linux-media@vger.kernel.org Such tool like patchwork.kernel.org will cares about patches, so they don't lost.

Are you going to submit the driver code as well to the list?

But this driver is only for the blackfin processor and will not work on other platforms. Does it make sense to include the driver to the kernel source? Maybe it will be better to include this driver to the blackfin.uclinux kernel tree. How do you think?

Please submit the driver to linux-media. The proper place for those drivers are under drivers/media. We have also other drivers there that are architecture specific (like omap drivers, OLPC, etc).
