8 years ago[media] bttv: Width must be a multiple of 16 when capturing planar formats
Hans de Goede [Sun, 7 Feb 2016 11:24:29 +0000 (09:24 -0200)]
[media] bttv: Width must be a multiple of 16 when capturing planar formats

On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).

This turns out to be caused by max-width (924) not being a multiple of 16.

We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.

The Timberdale FPGA video driver has not seen any real development
since 2011 (and very little before that).

One of the problems with the timblogiw driver is that it uses videobuf
instead of the newer vb2 framework. The long term goal is to either
convert or remove any driver still using videobuf. Since none of the
core v4l developers has the hardware, we cannot convert it ourselves.

As far as I can tell it was only used in an Intel demo board in 2009
using Meego:

http://www.chinait.com/intelcontent/intelprc/admin/PDFFile/20106411545.pdf

which has since been superseded.

Moving this driver to staging is the first step towards removal. After 2 or
3 kernel cycles it will be removed altogether unless someone steps up to
clean up this driver.

Merge branch 'fixes' into patchwork

Some macros were changed/removed at the material for v4.5. We need
to sync with those changes here, in order to avoid troubles.

* v4l_for_linus:
  [media] media.h: get rid of MEDIA_ENT_F_CONN_TEST
  [media] [for,v4.5] media.h: increase the spacing between function ranges
  [media] media: i2c/adp1653: probe: fix erroneous return value
  [media] media: davinci_vpfe: fix missing unlock on error in vpfe_prepare_pipeline()

not too late.

[media] [for,v4.5] media.h: increase the spacing between function ranges

Each function range is quite narrow and especially for connectors this
will pose a problem. Increase the function ranges while we still can and
move the connector range to the end so that range is practically limitless.

[media] tvp5150: replace MEDIA_ENT_F_CONN_TEST by a control

MEDIA_ENT_F_CONN_TEST is not really a connector, it is actually
a signal generator. Also, as other drivers use the
V4L2_CID_TEST_PATTERN control for signal generators, let's change
the driver accordingly.

Tested with Terratec Grabster AV350.

[media] v4l2-mc: remove the unused sensor var

This fixes this warning:

v4l2-mc.c: In function 'v4l2_mc_create_media_graph':
v4l2-mc.c:60:69: warning: variable 'sensor' set but not used [-Wunused-but-set-variable]

We could solve it the other way: don't do the second loop for
webcams. However, that would fail if a chip would have two sensors
plugged. This is not the current case, but it doesn't hurt to be
future-safe here, specially since this code runs only once during
device probe. So, performance is not an issue here.
