[media] docs-rst: fix cross-references for videodev2.h
There are several broken references there, due to the conversion to
C domain. Fix them using this shell script and manually adjust what's
broken:
# funcs is a file with the broken functions/references
for i in $(cat funcs|sort|uniq|perl -ne 'print "$1\n" if (m/(\S+)$/)'); do
i=${i//-/_}
echo $i
j=${i//_/-}
for k in $(git grep -l "_$j:" Documentation/); do
sed s,\_$j\:,"c\:type\:\: $i", <$k >a && mv a $k
done
for k in $(git grep -l "$j" Documentation/media/*.exceptions); do
sed s,$j,":c\:type\:\`$i\`", <$k >a && mv a $k
done
for k in $(git grep -l "$j" Documentation/); do
sed "s,:ref:\`$i <$j>\`,:c:type:\`$i\`," <$k >a && mv a $k
sed "s,:ref:\`$j\`,:c:type:\`$i\`," <$k >a && mv a $k

[media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.

|
|
|
* - ``V4L2_QUANTIZATION_DEFAULT``
|
|
|
|
|
- Use the default quantization encoding as defined by the
|
|
|
|
|
colorspace. This is always full range for R'G'B' (except for the
|
|
|
|
|
BT.2020 colorspace) and usually limited range for Y'CbCr.
|
|
|
|
|
* - ``V4L2_QUANTIZATION_FULL_RANGE``
|
|
|
|
|
- Use the full range quantization encoding. I.e. the range [0…1] is
|
|
|
|
|
mapped to [0…255] (with possible clipping to [1…254] to avoid the
|
|
|
|
|
0x00 and 0xff values). Cb and Cr are mapped from [-0.5…0.5] to
|
|
|
|
|
[0…255] (with possible clipping to [1…254] to avoid the 0x00 and
|
|
|
|
|
0xff values).
|
|
|
|
|
* - ``V4L2_QUANTIZATION_LIM_RANGE``
|
|
|
|
|
- Use the limited range quantization encoding. I.e. the range [0…1]
|
|
|
|
|
is mapped to [16…235]. Cb and Cr are mapped from [-0.5…0.5] to
|
|
|
|
|
[16…240].
