I have a number of comments below, but I will need to find the actual standards documents at work to verify some others parts of this RFC. So I'll get back with more comments, hopefully on Tuesday. I also have a few more generic comments: 1) I understand that the MFC supports H264, MPEG4 and H263, right? How does one select between them? I assume that V4L2_CID_MPEG_VIDEO_ENCODING should be used for that, but that is missing MPEG4 and H263. 2) It is sometimes hard to figure out for which video encodings certain controls are valid. I think all the video controls should have a list of the video encodings for which that control is valid (except where the name of the control makes it unambiguous). 3) Is there public documentation from Samsung regarding the MFC-specific controls? If so, then a link to that documentation would be very handy. If not, then I think some of the documentation for these controls should be extended. Note that this third version of the RFC looks much better than the earlier ones. I think we are close to finalizing this. > > Best regards, > Kamil Debski > > Signed-off-by: Kamil Debski <k.debski@xxxxxxxxxxx> > Signed-off-by: Kyungmin Park <kyungmin.park@xxxxxxxxxxx> > --- > Documentation/DocBook/v4l/controls.xml | 774 ++++++++++++++++++++++++++++++++ > include/linux/videodev2.h | 149 ++++++ > 2 files changed, 923 insertions(+), 0 deletions(-) > > diff --git a/Documentation/DocBook/v4l/controls.xml b/Documentation/DocBook/v4l/controls.xml > index 6880798..3c3c709 100644 > --- a/Documentation/DocBook/v4l/controls.xml > +++ b/Documentation/DocBook/v4l/controls.xml > @@ -325,6 +325,22 @@ minimum value disables backlight compensation.</entry> > <constant>V4L2_CID_ILLUMINATORS_2</constant> + 1).</entry> > </row> > <row> > + <entry><constant>V4L2_CID_MIN_BUFFERS_FOR_CAPTURE</constant></entry> > + <entry>integer</entry> > + <entry>This is a read only control that can be read by the application typo: read-only > +and used as a hint to determine the number of CAPTURE buffer to pass to REQBUFS. typo: buffers > +The value is the minimum number of CAPTURE buffer that it necessary for hardware typo: 'buffers that is' > +to work.</entry> > + </row> > + <row> > + <entry><constant>V4L2_CID_MIN_BUFFERSS_FOR_OUTPUT</constant></entry> typo: BUFFERSS -> BUFFERS > + <entry>integer</entry> > + <entry>This is a read only control that can br read by the application typo: read-only typo: br -> be > +and used as a hint to determine the number of OUTPUT buffer to pass to REQBUFS. typo: buffers > +The value is the minimum number of OUTPUT buffer that it necessary for hardware typo: buffers that is > +to work.</entry> > + </row> > + <row> > <entry><constant>V4L2_CID_PRIVATE_BASE</constant></entry> > <entry></entry> > <entry>ID of the first custom (driver specific) control. > @@ -1409,6 +1425,764 @@ of the video.
