There is another solution by Sensoray based on Stream-machine chip. We have used both the Kfir and the sensoray board on RH 7.2 http://www.sensoray.com/html/616data.htm
There are a couple of differences. I would say the Sensoray/Stream machine does a bit better job of encoding, but that may be subjective. Sensoray is more $$. Sensoray also does decoding. Kfir behaves strangely if you remove your video source. Being a commercial product (you would think) Sensoray is doing a bit more to support their driver. At this time, the driver is a bit flaky, but have got it to work. They are working on making it better. ----- Original Message ----- From: "torsten" <[EMAIL PROTECTED]> To: "Christian Zoffoli" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, November 17, 2002 5:46 PM Subject: [mpeg2] Re: kfir MPEG 2 Board > > > > > as i can see on the spec details the LML1011 (the only on that make MPEG > > in hw) works at lower resolution (and only MPEG1).
