Thanks

Nice work Majortrips. I'm still in the middle of moving so I haven't gotten a chance to test this yet, but it's really great to see this driver. There are some cleanups I found I need to do. Unplugging the cam while streaming has the potential to soft-lock the system, and I don't have support for p...

Added back in a decoder

I added a very simple YUYV to YUV420 trans-coder to the driver after looking through the sources of a number of projects. Yes the V4L group would like user land to handle this sort of conversion, but most of the user land code I have managed to look at throws errors at the user about the driver bein...

camE and Camorama

Neither camE nor Camorama support YUYV pixel formats. Kicking them out of my test list.

ov534 v0.3

Talked with Jim a bit in email, and read through much of the V4L2 API documents. Based on both inputs I gutted the built in YUYV decoder. I am up to v0.3 of the sources and have xawtv working at 640x480, full color. Simply had to start xawtv with the right -geometry for the image and all worked perf...

OV534 status

Have integrated a YUYV to RGB/BGR decoder into the driver (borrowed the YUV_TO_RGB_BY_THE_BOOK() interface from the usbvision.c/ibmcam.c drivers) , so color works now. The driver is performing asynchronous streaming using a kernel thread to continually build a stack of frame buffers on the side and ...

Re: Eventually it happened...

Though I am currently having an issue with the color. Very green. The driver sets up the pixel format as YUYV, but I am not so certain this YUYV is the same as the one V4L is expecting. Y,U,V,Y 4:2:2? Found another peculiar issue, the bulk read comes up 4 bytes short every time (one pixel?). Only r...

Eventually it happened...

It'll happen eventually... my example code shows enough to display a basic video feed. But nobody's written a real driver yet for Linux. I have video streaming working from an ov534.ko module I wrote using your code and the vivi V4L2 driver. Though I am currently having an issue with the color. Ver...
