This weekend, I found Cuse4BSD on your homepage replacing video4bsd. Now my DVB-T stick basically work. Thanks a lot for all your effort! I wanted to complain about the firmware path being /, but since you added the '-f' switch that comes down to the rather unimportant default being / and not -- for example -- /boot/modules/. Having to call webcamd twice, once to load the firmware and once to actually do its job is a little counter intuitive. My major problem at the moment is the quality of the signal. That has always been dependent on the location of the antenna in my apartment, but I just tried Raaf's dvbusb driver under FreeBSD 7 without having any distortions and immediately booted back into FreeBSD 8: The distortions are so high that it is unwatchable and after a few seconds audio and video are out of sync using Raaf's typhony (Kaffeine seems a little better at keeping the streams at sync even with a bad signal). I already checked the system load on my atom based system: 15% user, 10% system, 70% idle (8% python, 8% mplayer, 4% webcamd) or 15% user, 20% system, 60% idle (20% kaffeine, 7% webcamd, 5% Xorg) -- that does not seem problematic. (I thought with the driver now partially in user space there might be higher load than before due to context switching.) I am currently on FreeBSD 8.0-RELEASE with the libusb patch you advertised last week on your homepage. I would not like to bring my atom based system to 8-STABLE or 9-CURRENT. Would that help? Any idea or fix for my distortions? Cheers, Jan Henrik
