Well, I think I implemented almost all of the v4l2 framework. Then I took the FreeBSD bktr driver, separated the radio/tuner part and got it working as a v4l2 aware driver, too. This driver registers with the framework and a /dev/v4l2/radio0 entry is being created. I got fmtools-0.99.0 up and running, too. But there is a difference to the original Linux framework. AFAIR, in Linux, one of the kernel structures holds the open file handle, but in FreeBSD there's no place for it. So I changed the internals of the framework a bit, but the API for the applications should be the same as for Linux. What's missing is the video part. I had not enough specs about the v4l2 framework to get it running. And - what was the main problem for me - I did not have time to rewrite the bktr driver as v4l2 driver. You know, no information about the v4l2 framework and no information about the bktr driver internals ... so I gave up. > thanks > marco Ciao, Christian.
