Kernel configuration for ov9655 on the PXA27x Quick Capture Interface

Hi all,

I have an embedded smart camera equipped with an XScal-PXA270
processor running Linux 2.6.37 and the OV9655 Image sensor connected
on the PXA27x Quick Capture Interface.

Please, what kernel module I have to select in order to use the Image sensor ?

Thanks

Paolo Santinelli

IR for remote control not working for Hauppauge WinTV-HVR-1150 (SAA7134)

Hello,

I have a Hauppauge WinTV-HVR-1150 (model 67201) pci tv tuner working
(video and audio) under Ubuntu 10.10 and kernel 2.6.35-25. But the IR
sensor is not being detected and no input device is being created at
/proc/bus/input.

I have tried to follow the information from Jarod Wilson and Mauro
Carvalho Chehab in https://bugzilla.redhat.com/show_bug.cgi?id=665870
(regarding Fedora 14) but couldn't resolve it myself.

I'm not a kernel/driver specialist but from looking at the code I've
noticed that *perphaps* the support for the HVR-1150 has not been
finished yet. Here are two examples that leaded to this observation
(IMHO):

drivers/media/video/saa7134/saa7134-cards.c
-------------------------------------------------------------------------------
(...)
int saa7134_board_init1(struct saa7134_dev *dev)
{
(...)
       case SAA7134_BOARD_HAUPPAUGE_HVR1150:           *NO
INSTRUCTIONS FOR THIS CASE*
        case SAA7134_BOARD_HAUPPAUGE_HVR1120:
                /* GPIO 26 high for digital, low for analog */
                saa7134_set_gpio(dev, 26, 0);
                msleep(1);

                saa7134_set_gpio(dev, 22, 0);

There is a long delay when I use v4l2(uvc) with epoll (but select works well)

This is the strace result when use select

USB TV device / usbaudio / loud hum

Hi!

When I try to use my new USB TV tuner (Pinnacle PCTV USB2 PAL) on Fedora 14 (log 
messages: in the end) 
with this:
mplayer -tv 
driver=v4l2:input=0:width=768:height=576:device=/dev/video2:norm=5:chanlist=europe-west:freq=224.25
 tv://

I hear nothing, but I c good pictures...

When I use this command simultaneously:
parec --device=alsa_input.hw_1 > bla.raw
I get correct audio with strong noise:
http://www.wgboome.de./bla.wav
(it is from input=1 for copyright reasons... so there is silence plus noise)

according to "amixer -c1"
(card 0 is the audio device on the mainboard and
is handled by pulseaudio)
the PCTV audio device has mono audio:
Simple mixer control 'Line',0
  Capabilities: cvolume cvolume-joined cswitch cswitch-joined penum
  Capture channels: Mono
  Limits: Capture 0 - 16
  Mono: Capture 8 [50%] [0.00dB] [on]

but arecord wants "-c2"...

someone on linux media mailing list thinks,

Support to TT-budget S-1500b ?

Hi!
I bought PCI card  TT-budget S-1500 from dvbshop.net, but they send me 
new modification TT-budget S-1500b. The difference is in tuner - new 
code is BSBE1-D01A. The tuner itself is STB6000, but the QPSK 
demodulator is STx0288.
The card identify itself as:
Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
     Subsystem: Technotrend Systemtechnik GmbH Unknown device 101b
Is there any plan to support this device?

Thank you,
Penio Slavchev

patch for ov9655

Hi all,

I have an embedded smart camera equipped with an XScal-PXA270
processor running Linux 2.6.23 (just updated) and
the OV9655 Image sensor.

I have seen some patch (https://patchwork.kernel.org/patch/16548/) for
the  OV9655 that have the cropping function built in  and appear  to
be better than the driver currently in use (X300 camera board),

Please, could somebody tell me how to patch my  Linux 2.6.23 kernel ?

Here is what happen when I try to patch the kernel:

[root <at> localhost linux-2.6.23]# cat Add-ov9655-camera-driver.patch |
patch -p2 --dry-run
patching file drivers/media/video/Kconfig
Hunk #1 FAILED at 746.
1 out of 1 hunk FAILED -- saving rejects to file drivers/media/video/Kconfig.rej
patching file drivers/media/video/Makefile
Hunk #1 FAILED at 145.
1 out of 1 hunk FAILED -- saving rejects to file
drivers/media/video/Makefile.rej
The next patch would create the file drivers/media/video/ov9655.c,
which already exists!  Assume -R? [n]

Thank you.

Paolo

Osprey 440 - volume too low

Hello,

First, I'd like to apologize if this is the wrong place for this question.

I have an Osprey 440 video capture card that I'm trying to use with
linux kernel 2.6.32-5 on my debian system. While video is all right.
I'm having trouble with the audio for this device. The volume is very low.

The card itself is plugged into a PCI 32 bit socket.

arecord -L reports the following:
