Neither Alsa-OSS nor Pulse-OSS worked.
Well I would say it the other way there was no developer that made the mjpegtools support for ALSA, and the OSS emulation worked not well. v4l2 should have worked I think just for video recording with the patch. The problem was than that the card did support v4l2, as far as I remember but you needed mplayer to get a picture on the screen (xawtv and other TV Apps didn't work). But with that the recording didn't work. I stopped using the mjpegtools based cards (Iomega BUZ, Pinnacle DC30) about the time the 2.6.3x Kernel came around. Not sure which kernel it was. Currently lavplay is not working with the OSS emulation to play back a video and sound. playing back without sound still work. > It seems like the code is not really maintained any more.

All the analog stuff is fading away. You are right, hardware compression is not a problem any more, there are fast CPU and GPU available, and a modern harddisk is even able to write the raw data (~100MB/s), that was not able on normal consumer hardware when the Zoran chipset was developed. The Hardware I currently use is a Canopus ADVC-100, a firewire based external box which works well.

We will see what happens, I didn't get any word from the kernel developers. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: shadowl...@utanet.at www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
