Re: New media framework user space usage
Hello Eino-Ville,
Most of the ISP can't handle more than 10-bit input - unless you're
streaming raw sensor data straight to memory, you'll have to use the bridge
lane shifter to decimate the input.
In the new framework, I don't know how that's done, unfortunately.
Thank you for pointing me to it. Now I read about it in the technical
reference manual too
(http://focus.ti.com/lit/ug/spruf98k/spruf98k.pdf).
At page 1392 it mentions the possibility to reduce the precision from
12- to 10-bit. It turns out Laurent already sent me the right
configuration in a side note of a former post of me. On page 1574 I
found another related register: CCDC_FMTCFG. Here you can select which
10 of the 12 bits you want to keep.
I looked up the code-flow for the isp-framework and post it here for reference:
static struct isp_v4l2_subdevs_group bastix_camera_subdevs[] = {
{
.subdevs = bastix_camera_mt9p031,
.interface = ISP_INTERFACE_PARALLEL,
.bus = { .parallel = {
.data_lane_shift= 1,
.clk_pol= 1,
.bridge = ISPCTRL_PAR_BRIDGE_DISABLE,
} },
},
{ NULL, 0, },
};
static struct isp_platform_data bastix_isp_platform_data = {
.subdevs = bastix_camera_subdevs,
};
...
omap3isp_device.dev.platform_data = bastix_isp_platform_data;
---
The config is handled in isp.c here:
void isp_configure_bridge(struct isp_device *isp, enum ccdc_input_entity input,
const struct isp_parallel_platform_data *pdata)
{
...
switch (input) {
case CCDC_INPUT_PARALLEL:
ispctrl_val |= ISPCTRL_PAR_SER_CLK_SEL_PARALLEL;
ispctrl_val |= pdata-data_lane_shift
ISPCTRL_SHIFT_SHIFT;
ispctrl_val |= pdata-clk_pol ISPCTRL_PAR_CLK_POL_SHIFT;
ispctrl_val |= pdata-bridge ISPCTRL_PAR_BRIDGE_SHIFT;
break;
...
}
Also, technically, the mt9p031 output colorspace is not sRGB, although I'm
not sure how close it is. It's its own sensor-specific space, determined by
the color filters on it, and you'll want to calibrate for it at some point.
The output format of the sensor is
R Gr
Gb B
The same colorspace is given as example in spruf98k on page 1409.
There I am still confused about the sematic of 1 pixel. Is it the
quadruple of the bayer values or each component? Or does it depend on
the context? Does the the sensor send 5MP data to the isp or 5MPx4
bayer values? Does the 12-bit width belong to each bayer value? In the
sensor you read from right to left, I don't know if the ISP doc means
reading left to right. And so on and so on...
Good luck,
As you can see I need and appreciate it :)
About the freezing ioctl. I discovered that I have a clocking issue. I
will solve it monday and see if it works better and had an impact on
the isp-driver.

Terratec Cinergy Hybrid T USB XS
Hello,
I found that the problems people have reported with the USB-TV-stick
Terratec Cinergy Hybrid T USB XS (USB-ID: 0ccd:0042)
are coming from a wrong header file in the v4l-sources.
Attached is a diff, which fixes the problem (tested successfully here).
Obviously the USB-ID has been associated with a wrong chip: EM2880
instead of EM2882, which would be correct.
Thanks and best regards,
Philippe Bourdin.

Success on Analog signal: Yuan MPC788
I thought I would report the success on had on the Yuan MPC788 Mini-PCI card. I can only verify the analog signal as it is a DVB-T digital card and I'm in Canada, so no signal to check it against, though kaffeine sees it clearly and does scan for channels although it doesn't find anything. As for the drivers, it is correctly detected against the cx88xx module, however I had to use the options cx88xx card=81 in the /etc/ modprobe.d/video4linux file. This along with using the xc3028_v27.fw file, I have the analog NTSC working perfectly. This card has the same components as the Leadtek Winfast DTV1800 card. Hope this helps others.

As this is static, you could just name it as:

and use module_param() instead.
OK.

You don't need it. This is always false upstream.
OK.
[...]
Don't implement your own IR RC5 decoding logic. We have it already at IR
core, and it is able to handle several protocols. Instead, just sent the
raw events to RC core.
See drivers/media/dvb/siano/smsir.c for an example on how to do it.
[...]
Also, don't put the RC tables at the driver. Move it to a separate file, at
drivers/media/IR/keymaps/. This allows importing the RC keycodes by
ir-keytable userspace tool (from v4l-utils.git).
Everythings' done. Ported to use ir-rc5-decoder. Rebased and squashed.
So, please pull now from:
