Hi Tiffany,
Some more comments, most are trivial but I realized that you were basing this
patch on an older kernel and not the latest media_tree master branch.
That's a bit of a killer because otherwise I am very close to merging this.

Unspport -> Unsupported
But either remove this or make it a debug message.
I would just remove it.

This week a commit was added that adds a device_caps field to struct video_device.
Please set the device caps there and the v4l2 core will take care of setting
device_caps and capabilities here. So these two lines can then be removed.
The advantage going forward is that the v4l2 core now knows the capabilities
of each video device.

... move this out of the 'else' since this is common for both capture and output.

This is a bit dubious. I would just set flags and 'reserved' to 0. You want
to handle ycbcr_enc, quantization and xfer_func just like you handle the
colorspace field.

Ugly indentation. Looks like there is a tab too many.

This is for backward compatibility.
Some our branches use older kernel that do not have ycbcr_enc and
xfer_func field. We want these branches could directly cherry-pick
upstream encoder patches without any modification.
So we just set field after flag to 0.
