[PATCH/RFC v2 0/4] JPEG codecs control class

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This patch set adds new control class - V4L2_CID_JPEG_CLASS with initially
four controls in it. It also adds V4L2_CID_JPEG_COMPRESSION_QUALITY control
to two gspca sub-devices: sonixj and zc3xx, as these where drivers I had
the hardware handy for. The gspca patches have been tested with v4l2ucp
and v4l2-ctl.

I could provide patches for some other drivers that currently use
VIDIOC_S/G_JPEGCOMP ioctls for image quality setting only.

The initial RFC can be found at
http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg39012.html

Changes since v1 [1]:
 - renamed trailing 'S' from V4L2_CID_JPEG_ACTIVE_MARKERS;
 - removed V4L2_JPEG_ACTIVE_MARKER_DAC and V4L2_JPEG_ACTIVE_MARKER_DNL
   definitions as these are normally controlled by higher level compression
   attributes and shouldn't be allowed to be discarded independently;

These patches are intended for v3.4. Comments are welcome.
