I'm running an AMD 1.1Ghz Athlon on an ASUS A7V133 with Redhat 8.0. The card is a Hauppauge WinTV (BT878 rev 17). I'm also loading the bttv module with gbuffers=32 (this helps). I'm trying to capture at 29.97 FPS with the card at either 640x480 or 400x304. Using either ffmpeg (better) or streamer, the cpu is only hitting about 65% utilization but I'm still getting dropped frames. The questions are: can this card cut it? are there any other optimizations that I should try? perhaps in bios? Adding gbuffers over 32 doesn't seem to help. More than 64 and the capture programs segfault. Any solution that uses more RAM is fine up to a limit of about 512MB. thanks
