It turns out that we have both JPEG and Motion-JPEG pixel formats defined. Furthermore, some drivers support one, some the other and some both. These pixelformats both mean the same. I propose that we settle on JPEG (since it seems to be used most often) and add JPEG support to those drivers that currently only use MJPEG. We also need to update the V4L2_PIX_FMT_JPEG documentation since it just says TBD: https://www.linuxtv.org/downloads/v4l-dvb-apis-new/uapi/v4l/pixfmt-compressed.html $ git grep -l V4L2_PIX_FMT_MJPEG drivers/media/pci/meye/meye.c drivers/media/pci/solo6x10/solo6x10-v4l2-enc.c drivers/media/platform/sti/delta/delta-cfg.h drivers/media/platform/sti/delta/delta-mjpeg-dec.c drivers/media/usb/cpia2/cpia2_v4l.c drivers/media/usb/go7007/go7007-driver.c drivers/media/usb/go7007/go7007-fw.c drivers/media/usb/go7007/go7007-v4l2.c drivers/media/usb/s2255/s2255drv.c drivers/media/usb/uvc/uvc_driver.c drivers/staging/media/zoran/zoran_driver.c drivers/staging/vc04_services/bcm2835-camera/bcm2835-camera.c drivers/usb/gadget/function/uvc_v4l2.c It looks like s2255 and cpia2 support both already, so that would leave 8 drivers that need to be modified, uvc being the most important of the lot. Any comments? Regards, Hans
