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 */ </pre> Fernando Laudares Camargos 2011-02-15T20:27:29 http://comments.gmane.org/gmane.comp.video.video4linux/44118 <pre>This is the strace result when use select select(5, [4], ...) = 1 (in [4], left {1, 648368}) &lt;0.036166&gt; ioctl(4, VIDIOC_DQBUF, 0x7fffbe72ce50) = 0 &lt;0.000024&gt; ioctl(4, VIDIOC_QBUF or VT_SETACTIVATE, 0x7fffbe72ce50) = 0 &lt;0.000021&gt; select(5, [4], NULL, NULL, {2, 0}) = 1 (in [4], left {1, 680471}) &lt;0.319565&gt; ioctl(4, VIDIOC_DQBUF, 0x7fffbe72ce50) = 0 &lt;0.000023&gt; ioctl(4, VIDIOC_QBUF or VT_SETACTIVATE, 0x7fffbe72ce50) = 0 &lt;0.000019&gt; select(5, [4], NULL, NULL, {2, 0}) = 1 (in [4], left {1, 680356}) &lt;0.319680&gt; ioctl(4, VIDIOC_DQBUF, 0x7fffbe72ce50) = 0 &lt;0.000022&gt; ioctl(4, VIDIOC_QBUF or VT_SETACTIVATE, 0x7fffbe72ce50) = 0 &lt;0.000019&gt; select(5, [4], NULL, NULL, {2, 0}) = 1 (in [4], left {1, 648366}) &lt;0.351672&gt; ioctl(4, VIDIOC_DQBUF, 0x7fffbe72ce50) = 0 &lt;0.000022&gt; ioctl(4, VIDIOC_QBUF or VT_SETACTIVATE, 0x7fffbe72ce50) = 0 &lt;0.000018&gt; select(5, [4], NULL, NULL, {2, 0}) = 1 (in [4], left {1, 680368}) &lt;0.319669&gt; ioctl(4, VIDIOC_DQBUF, 0x7fffbe72ce50) = 0 &lt;0.000022&gt; ioctl(4, VIDIOC_QBUF or VT_SETACTIVATE, 0x7fffbe72ce50) </pre> xinglp 2011-02-15T09:47:39 http://comments.gmane.org/gmane.comp.video.video4linux/44117 <pre>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 &gt; 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, that somehow YUV data might get into the audio stream...

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?

I am asking help, my goal is capture a subfield of the whole image. How to do it? Is this function (VIDIOCSCAPTURE or something else?) supported by the Video4Linux driver for the OV9655 Image sensor ? Currently I am able to reconfigure the OV9655 in order to change the whole image resolution, 640x480, 320x240 and even lower. The problem is I need do it dynamically, quickly, without close the camera and then reopen it every time I need sub-capture the image. I don't have any experience using device driver. I have tried to change the capture area using this call: vw.width = new_image_width; vw.height = new_image_height; ioctl(fd_camera, VIDIOCSWIN, &amp;vw) where vw is a struct video_window. I get the right image but it seems to be not vertically centred, it appears shifted and wrapped vertically. To get the right image I h</pre> Paolo Santinelli 2011-01-26T20:45:29 http://comments.gmane.org/gmane.comp.video.video4linux/44091 <pre>http://tertuliasvirtuales.com/images/mto.php -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request&lt; at &gt;redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list </pre> Mike Farrell 2011-01-26T10:52:16 http://comments.gmane.org/gmane.comp.video.video4linux/44089 <pre>http://colbatol.com/images/mto.php -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request&lt; at &gt;redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list </pre> Mike Farrell 2011-01-24T12:25:01 http://comments.gmane.org/gmane.comp.video.video4linux/44088 <pre>Hi, I was trying to understand v4l2.

I have some logs and some results, but my main problem is that I cannot see how the driver should works. I mean which module calls in the others, and where starts the whole thing. :) As far as I could see more than one module contains for example tda829x specific parts. My other problem is I haven't got any circuit diagram to know the connections, but I guess it is a usual thing. Furthermore in my future plans I would like to use this hybrid card as a signal processor module for some kind of hobby, and to give a good start to others. In my plan I would like to prepare a GUI, where I could modify all of the parameters in all chips on the board, but I guess the limitations in ioctl are much more strong than I could achieve that. Could you please help me, how should I start working, or much better, how should I continue.. :) Thanks a lot! </pre> Norbert Plótár 2011-01-19T18:51:07 http://comments.gmane.org/gmane.comp.video.video4linux/44086 <pre>http://leskdorducabaret.fr/images/mto.php -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request&lt; at &gt;redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list </pre> Mike Farrell 2011-01-16T09:42:40 http://comments.gmane.org/gmane.comp.video.video4linux/44085 <pre>http://habitatsympa.com/images/mto.php -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request&lt; at &gt;redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list </pre> Mike Farrell 2011-01-13T21:29:21 http://comments.gmane.org/gmane.comp.video.video4linux/44084 <pre>Hello, We are trying to use two Sensoray 611 frame grabbers in a 64-bit RHEL5 system.
