I can imagine that. I have similar problems, but I'm a little surprised your system works as good as it does. > It might have something to do with the order in which the cards are > initialized when all cards are found first an then initialized it seems > to work, but when a card is initialized before other cards are found > then there is an error. That is most likely the problem, yes. If you dig at the really low levels in the initialization routines, you'll probably find out that the video encoders and decoders are initialized at least nine times each per card, due to some peculiarities concerning the interaction between i2c buses and i2c devices. In short, the kernel should see each encoder and decoder once for every i2c bus on each of the cards, but as things are now, all of them are visible, without any buses differentiating them. If this is the culprit, it has been identified, and is being worked on by Jean Delvare. I don't know what the time table looks like; there's quite a bit of fiddling involved. You _might_ be helped by manually modprobing the encoder and decoder drivers before zr63060. Follow-up question: Are you using the on-board composite output connector? My DC10+ stops after a number of frames when playing with lavplay -pC, stalling waiting for a buffer. I've reduced it to some kind of race condition, but I'm not sure where to go from there, or if indeed any other DC10+ users than me experience the problem. /Sam ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mjpeg-users mailing list Mjpeg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mjpeg-users
