Another stab in the dark; perhaps force a format.

Re: [Mjpeg-users] Zoran Pinnacle DC10
Hallo > I need to send video to a TV by using the Zoran Pinacle DC10 PCI card > through a program written in c. > Could you recommend some libraries to use the functions of the board?. When you look at the mjpegtools, take a look a the lavplay program. That program can put a mjpeg file to the zoran card. The other program I know is mplayer with zoran support complied in (mplayer -vo zr). You can take a look at both programs. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: shadowl...@utanet.at www: http://www.lysator.liu.se/~gz/bernhard -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

That's a tricky question. I'd ask on a lives mailinglist. I remember that there was once a lives output plugin for the mjpegtools.

I have tired that command: mencoder DVD.mpg -o test4.avi -oac copy -ovc lavc -lavcopts vcodec=mjpeg:vbitrate=15000 There mplayer tells me that I have used a MJPG coded. But it seems to me that they don't include a huffman table or at least in a different way.
