[media] cx23885: Bugfix /sys/class/video4linux/videoX/name truncation · 9def5ed7

由 Steven Toth 提交于 1月 04, 2012

The card names are being truncated in the video4linux sys class name file.
Prior to this patch they were shown as:
cx23885[0] mpeg (Hauppauge WinT
cx23885[0] video (Hauppauge WinT
cx23885[0] vbi (Hauppauge WinT

After this patch they are shown as:
Hauppauge WinTV-HVR1850 (video)
Hauppauge WinTV-HVR1850 (mpeg)
Hauppauge WinTV-HVR1850 (vbi)

[media] cx23885: Control cleanup on the MPEG Encoder · 09b3bc22

由 Steven Toth 提交于 1月 04, 2012

Added three new control calls (g_std, querystd and g_ctrl) to
the -417 driver. Also routed other controls through the main
cx23885 driver meaning that the controls for the 417 and the
raw video device all enter the driver code and are handled
in a single place.

[media] cx23885: Hauppauge HVR1850 Analog driver support · 35045137

由 Steven Toth 提交于 1月 04, 2012

First in a series of patches that adds support to the cx23885 driver
for CX23888 analog video handling. Raw and MPEG video support is
being added for the HVR1850 driver in the patch, and the following
series of patches.

Some basic cx23885 driver cleanup. Partly to add HVR1850 support
and partly to allow -417.c V4L2 calls to be routed through thr
driver core and handled in a single place.

Make a number of core driver functions available to the -417.c
driver to streamline the driver.

Add the analog tuner ops definition so we can reach/tune the
hardware when we need to. Added the tff field so 888 based cards
(which have a weird field ordering issue) can be accomodated
and worked around in the driver.

[media] cx23885: Configure the MPEG encoder early to avoid jerky video · 9c9c3d07

由 Steven Toth 提交于 1月 04, 2012

Found an odd bug while implementing support for the HVR1850 that
lead to jerky video during the first capture, if the encoder was
not initialized early. I've modied the driver to configure the
encoder early, and this avoids the issue - a reasonable workaround.

Regression tested against the HVR1800 and soon to be added HVR1850

[media] cx25840 / cx23885: Fixing audio/volume regression · 4c3764d1

由 Steven Toth 提交于 1月 04, 2012

Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control
definition and now audio is working reliably again.

[media] cx23885-dvb: Remove a dirty hack that would require DVBv3 · a7d44baa

由 Mauro Carvalho Chehab 提交于 12月 26, 2011

The cx23885-dvb driver has a dirty hack:
	1) it hooks the DVBv3 legacy call to FE_SET_FRONTEND;
	2) it uses internally the DVBv3 struct to decide some
	   configs.

Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.

Compile-tested only.

[media] video: Drop undue references to i2c-algo-bit · a824f0f4

由 Jean Delvare 提交于 11月 09, 2011

There's one comment that has been copied from bttv to many other
media/video drivers:

/* init + register i2c algo-bit adapter */

Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.
