media: vidioc-enum-fmt.rst: clarify format preference

2019-12-16T09:24:55+00:00

It has been decided to use the ENUM_FMT index value as a hint for driver preference. This is defined purposedly in a very liberal way, letting drivers define what "preference" means. For instance, the Hantro VPU driver indicates additional processing to output a given format, and thus implicates more CPU usage, which is enumerated after native (non-processed) formats.

media: pixfmt-tch-td16/tu16.rst: document that this is little endian

2019-12-16T09:21:14+00:00

Testing with the rmi_f54 driver on the Lenovo X1 Carbon 6th gen laptop showed that the data is in little endian format. Update the documentation accordingly. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: ivtv/cx18: remove ivtvdriver.org references

2019-12-13T08:27:09+00:00

That URL is no longer valid, so either remove references to it or replace it with linuxtv.org. Rather than updating the URL I've just dropped the cx18.rst driver documentation since it was really out of date.

media: vidioc-g-dv-timings.rst: fix wrong porch

2019-12-13T08:23:09+00:00

It is the vfrontporch of field 1 that is one half-line longer, not the backporch. The order of the vertical signals in an interlaced system is: Field 1: vsync vbackporch active video of field 1 vfrontporch + 0.5 Field 2: il_vsync il_vbackporch - 0.5 active video of field 2 il_vfrontporch Interlaced systems that use HALF_LINE set the il_ fields as follows: il_vfrontporch = vfrontporch il_vsync = vsync il_vbackporch = vbackporch + 1 So the total vertical blanking for field 1 is: vsync + vbackporch + vfrontporch + 0.5 and for field 2: vsync + vbackporch + 1 + vfrontporch - 0.5 == vsync + vbackporch + vfrontporch + 0.5 So each field has the same number of half-lines.

Some sensors have optical blanking areas, this is, pixels that are painted and do not account for light, only noise. These special pixels are very useful for calibrating the sensor, but should not be displayed on a DEFAULT target.

media: uapi: h264: clarify expected scaling_list_4x4/8x8 order

2019-11-09T07:46:07+00:00

Clarify that the expected order of scaling lists should follow the order they are listed in the H264 standard. The expected scaling list order, for 4x4: Intra Y, Intra Cb, Intra Cr, Inter Y, Inter Cb, Inter Cr, for 8x8: Intra Y, Inter Y, Intra Cb, Inter Cb, Intra Cr, Inter Cr. Also clarify that the values in a scaling list should be in matrix order, the same value order that vaapi, vdpau and nvdec use.
