In the fwht_encode_frame, 'encoding = encode_plane'
should be replaced with 'encoding |= encode_plane'
so existing flags won't be overwrriten.

Add support for the selection api for the crop and compose targets.
The driver rounds up the coded width and height such that
all planes dimensions are multiple of 8.

Add flags indicating the pixel encoding - yuv/rgb/hsv to
fwht header and to the pixel info. Use it to enumerate
the supported pixel formats.

I think we should reserve 3 bits for this, so use GENMASK(20, 18).

I'd change this to:

RGB: (2 << 18)
HSV: (3 << 18)

A pixenc value of 0 means that we are dealing with an old header. So we can
replace the version check with:
(!pixenc || v4l2_fwht_pixfmts[i].pixenc == pixenc) &&
> + (version == 1 || v4l2_fwht_pixfmts[i].components_num == components_num)) {
I don't think this is right. If this is an old header version, then we should only match
formats with 3 components. So I'd drop the version check here and just ensure that
components_num is always 3 if we have an old header.
Note that with these changes the version argument can be dropped as well.

The components check should be done after this 'if'. Since it also is

This can be simplified: there is no need to pass the header since it can be
obtained via ctx. And rather than passing p_src, sz and pp you can pass pp and
the remaining sz in the buffer.

Hmm, I think the original code is a bit buggy. I don't think it will find
the correct header in some circumstances: e.g. a sequence of 5 0x4f bytes
followed by 4 0xff bytes will likely fail.
Try to prepend a 0x4f byte to a fwht bitstream and see if that works. I think
it will fail to find the header.
Anyway, that can be fixed in a separate patch.
I think a proper solution just counts the number of consecutive 0x4f bytes
and the number of consecutive 0xff bytes that follow.
The magic header sequence is found if the 0x4f count >= 4 and the 0xff count == 4.
There is no need to copy the magic header sequence to state.header in this case
since it is really just a state machine. I suspect it will actually make the code
simpler.

...and also these two. After all, this only needs to be done when a new header
was found.

If the the queues are not streaming then the first resolution
change is handled in the buf_queue callback.
The following resolution change events are handled in job_ready.

Do this instead:

v4l2_m2m_buf_queue(ctx->fh.m2m_ctx, vbuf);

To be honest, this patch is hard to follow. Not your fault, it simply is difficult
code. I think that I will merge a v3 (with all the comments fixed) and then see if
I can refactor things to make the code easier to understand.
And while I do that, you can start work on the stateless codec, which is after all
the goal of your project :-)

Hans

You can simplify this by doing:
if ((V4L2_TYPE_IS_OUTPUT(q->type) && !ctx->is_enc) ||
(!V4L2_TYPE_IS_OUTPUT(q->type) && ctx->is_enc))
return 0;
And the remainder can be shifted one tab to the left.
