So what would those kernel patches be? Have they been posted anywhere? Coincidentally, I just installed a Hauppauge TV card recently, and had the same problem (capturing just a blue screen) that was discussed here. Now after setting the input to DEV1 (from DEV0) it works, but only up to quarter resolution (384x288). With any size larger than that, ffmpeg never records anything - the output file just contains the header. It also does not echo any status lines, nor does it react to the 'q' quit key at any resolution larger than 384x288, I have to ^c out. Would that be the result of improper sync generation as you indicated? Note that fxtv can display full resolution PAL TV without problem, and can even capture that, unencoded, to disk. It just gets a little bit bulky :-) -- Regards, Georg. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
