2011-12-30[media] v4l: Add new alpha component controlSylwester Nawrocki
The V4L2_CID_ALPHA_COMPONENT control is intended for the video capture or memory-to-memory devices that are capable of setting up the per-pixel alpha component to some arbitrary value. It allows to set the alpha component for all pixels to an arbitrary value.

2011-12-20[media] Update documentation to reflect DVB-C Annex A/C supportMauro Carvalho Chehab
Instead of using the same delivery system for both Annex A and Annex C, split them into two separate ones. This helps to support devices that only support Annex A. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-11-25[media] V4L2 spec: fix the description of V4L2_FBUF_CAP_SRC_CHROMAKEYHans Verkuil
V4L2_FBUF_CAP_SRC_CHROMAKEY is the opposite of V4L2_FBUF_CAP_CHROMAKEY, but according to the documentation it was the same. The terms 'video' and 'framebuffer' were accidentally swapped in the text.

2011-11-11[media] dvb: Allow select between DVB-C Annex A and Annex CMauro Carvalho Chehab
DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between Annex A and Annex C is that Annex C uses a subset of the modulation types, and uses a different rolloff factor. A different rolloff means that the bandwidth required is slicely different, and may affect the saw filter configuration at the tuners. Also, some demods have different configurations, depending on using Annex A or Annex C. So, allow userspace to specify it, by changing the rolloff factor.

2011-11-03[media] v4l: Add AUTO option for the V4L2_CID_POWER_LINE_FREQUENCY controlSylwester Nawrocki
V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct a driver what is the power line frequency so an appropriate filter can be used by the device to cancel flicker by compensating the light intensity ripple. Currently in the menu we have entries for 50 Hz and 60 Hz and for entirely disabling the anti-flicker filter. However some devices are capable of automatically detecting the frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

2011-09-21[media] videodev2.h: add V4L2_CTRL_FLAG_VOLATILEHans Verkuil
Add a new VOLATILE control flag that is set for volatile controls. That way applications know whether the value of the control is volatile (i.e. can change continuously) or not. Until now this was an internal property, but it is useful to know in userspace as well. A typical use case is the gain value when autogain is on. In that case the hardware will continuously adjust the gain based various environmental factors. This patch just adds and documents the flag, it's not yet used.
