The flags field can be removed from struct vicodec_q_data.
This simplifies the flags handling elsewhere.

Add support for 4:2:2, 4:4:4 and RGB 24/32 bits formats.
This makes it a lot more useful, esp. as a simple video compression
codec for use with v4l2-ctl/qvidcap.
Note that it does not do any conversion between e.g. 4:2:2 and 4:2:0
or RGB and YUV: it still just compresses
From: Hans Verkuil
Exit the loop immediately once it is clear that the plane
cannot be compressed. Also clear the PCODED bit and fix the
PCODED check (it should check for the bit) in the caller code.

cframe_hdr has been renamed to fwht_cframe_hdr, but the old name
was still used in two comments.

The codec source is generic and not vicodec specific. It can be used
by other drivers or userspace as well. So rename the source and header
to something more generic (codec-fwht.c/h) and prefix the defines, types
and functions with fwht_.

Instead of hardcoding the quantization parameter (or 'DEADZONE_WIDTH'
as it was called in the codec) make this configurable through two
controls: one for I frames, one for P frames.

- rename source and use proper prefixes for the codec: this makes it

media: af9035: prevents buffer overflow when less than 3 bytes are written to
the device
When less than 3 bytes are written to the device, memcpy is called with
negative array size which leads to buffer overflow and kernel panic. This
patch adds a condition and returns -EOPNOTSUPP instead.
Fixes

Hello,
One of the discussions we had when developing Vimc, was regarding
optimizing image generation.
The ideia was to generate the images directly in the capture instead
of propagating through the pipeline (to make things faster).
But my question is: if this optimization is on, and if there is a
