Proposed patch for libv4l-0.6.4 to support Asus K70AD where webcam is upsid down
I installed Ubuntu Karmic on a Asus laptop PRO79A equipped with a
motherboard K70AD. However, with the original libv4l-0.6.4 library, the
image of the webcam is upside down. I suggest you this little patch that
solved the problem on my machine.

[PATCH] saa7134: add capture boards Hawell HW-404M7 and HW-808M7
This patch adds new capture boards Hawell HW-404M7 and HW-808M7.
Those cards have 4 or 8 SAA7130 chips and for the work it only needs initialize
registers.
The value of those registers were dumped under Windows using flytest.
But board haven't EEPROM.
For the first chip:
SAA7130 (0x7130, SubVenID:1131, SubDevID:, Rev: 01)
I2C slave devices found:
No devices
GPIO pins:
Mode : 0x00389C00
Value: 0x00016C00
Video input: 3
Audio input: Analog Line1
For other chips:
SAA7130 (0x7130, SubVenID:1131, SubDevID:, Rev: 01)
I2C slave devices found:
No devices
GPIO pins:
Mode : 0x00389200
Value: 0x0001

Subject: [PATCH - FIX] V4L: vpfe_capture - free ccdc_lock when memory
allocation fails
From: Murali Karicheri m-kariche...@ti.com
This patch fixes a bug in vpfe_probe() that doesn't call mutex_unlock() if
memory
allocation for ccdc_cfg fails. See also the smatch warning report from Dan
Carpenter that shows this as an issue.

How to test s-video em28xx card input?
Hi, I would like to know how can I test the svideo input of a em28xx usb card. The svideo has a round 9-pin female connector so, if I'm not wrong, it should have also the audio in. Is it correct?

Re: [PATCH] DTV2000 H Plus issues
I have finally received some feedback on DVB-T, and it reportedly works, although with a minor bug: it was necessary to use the cable connector instead of the antenna one. There is an updated patch at the web page http://www.sharemation.com/IstvanV/v4l/xc4000.html that attempts to correct this problem. It also includes a few CX88 changes that are not related to adding support for XC4000 based cards, and could possibly be released as separate patches: - implements a sharpness control using the CX2388x peaking filter and changing the notch filter - in two places (cx88-core.c and cx88-video.c) code that checked for CX88_VMUX_TELEVISION did not also check for CX88_VMUX_CABLE; this was the reason why selecting the audio standard did not work for the cable input - in cx88-mpeg.c, there was code that set core-input to CX88_VMUX_DVB; this does not seem to make sense, since core-input is an index to an array (core-board.input), while the CX88_VMUX_* values are not intended to be used as indexes, but rather values of the 'type' member of struct cx88_input. But it is also not obvious if this has any actual effect other than what is reported as the current input when queried by an application. In any case, I changed the code to search for an input of type CX88_VMUX_DVB, or set the input to 0 if it is not found -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
USB TechnoTrend Connect S2-3650 CI + CAM's
Hello, I was just wondering, as there seem a complete driver available for this tuner and its CI interface, is anybody actually using this HW with MythTV or any other Linux TV solution? For now, the best CI option card has been the TT-S2-3200, but if this relatively new USB card works with HW CAM's too, it would be great news. I've been waiting for it for some time, it's a good add-on card for the few extra pay-services requiring non-standard CAM's (like DRE for Penthouse HD :)).

cx23885_wakeup: 32 buffers handled (should be 1)
I see messages like : cx23885_wakeup: 32 buffers handled (should be 1) in my logs on my mythtv box. I take it they're coming from my DVICO dual express 7 tuner card. The message always contains those numbers (32 and should be 1). It doesn't seem to cause me any troubles, I'm just curious about the message. A quick perusal of the code in cx23885-core.c doesn't look like this is an actual error condition--i.e. it looks like the driver is handling multiple messages. -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
