+Apply average blur filter.

+The filter accepts the following options:
+
+@table @option
+@item sizeX
+Set horizontal radius size. By default value is @code{1}.
State range as well for all options, e.g.
Range is @code{[1, 1024]} and default value is @code{1}.
+Insert a JPG logo in the bottom left corner of the input
Shouldn't this be top-left?
+@example
+-i INPUT -i LOGO -filter_complex
"[0:v]hwupload[a],[1:v]hwupload[b],[a][b]overlay_opencl[out],[out]hwdownload"
OUTPUT
Prefer this in recommended syntax:
"[0:v]hwupload[a];[1:v]hwupload[b];[a][b]overlay_opencl,hwdownload"
+@section tonemap_opencl
+Tone map colors from different dynamic ranges.
+
+Supported output formats: NV12/P010.
+
+@subsection Options
+The filter accepts the following options.
+
+@table @option
+@item tonemap
+Set the tone map algorithm to use.
+
+Possible values are:
+@table @var
+@item none
+Do not apply any tone map, only desaturate overbright pixels.
+
+@item linear
+Stretch the entire reference gamut to a linear multiple of the display.
+
+@end table
+
+Default is none.
+
+@item param
+Tune the tone mapping algorithm.
+
+This affects the following algorithms:
+@table @var
+@item none
+Ignored.
+
+@item linear
+Specifies the scale factor to use while stretching.
+Default to 1.0.
The filer source has many more options defined.
In addition, there are many missing values for the tonemap algo; it
appears not all are effected. If that's the case, remove or note that in
the AVOptions table.
Please document all effective options and their values.
+This filter does HDR(HDR10/HLG) to SDR conversion with tone-mapping with vaapi
codecs.
+@example
+-init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device opencl=ocl@@va
-hwaccel vaapi -hwaccel_device va -hwaccel_output_format vaapi -i INPUT
-filter_hw_device ocl -filter_complex
'[0:v]hwmap,tonemap_opencl=t=bt2020:tonemap=linear:format=p010[x1]
[x1]hwmap=derive_device=vaapi:reverse=1' -c:v hevc_vaapi -profile 2 OUTPUT
hwmap doc says reverse is a "dangerous" option and should be used with
care. Can you convert this example to one which doesn't use it?
---
There are 4 whitespace errors reported when applying the mbox. Doesn't
matter much in docs/* but do remove them during revision.
Please remember to state range/default for all options. If an option has
an alias, mention it, like in unsharp_opencl.
Thanks,
Gyan
