This patch addresses several issues pointed by Randy Dunlap <rdunlap@xenotime.net> at changeset ece722c: - In the generated index.html file, "media" is listed first, but it should be listed in alphabetical order, not first. - The generated files are (hidden) in .tmpmedia/ - The link from the top-level index.html file to "media" is to media/index.html, but the file is actually in .tmpmedia/media/index.html - Please build docs with and without using "O=builddir" and test that. - Would it be possible for media to have its own Makefile instead of merging into this one? Due to the way cleandocs target works, I had to rename the media DocBook to media_api, otherwise cleandocs would remove the /media directory. Thanks-to: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

<title>Description</title>
|
|
|
|
<para>The following four pixel formats are raw sRGB / Bayer formats with
|
|
12 bits per colour. Each colour component is stored in a 16-bit word, with 6
|
|
unused high bits filled with zeros. Each n-pixel row contains n/2 green samples
|
|
and n/2 blue or red samples, with alternating red and blue rows. Bytes are
|
|
stored in memory in little endian order. They are conventionally described
|
|
as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these
|
|
formats</para>
