Way cool man! Tried it immediately, it works but has some problems: - Strange varying latency. Bottom fields seem to take 60ms to capture, this is what gets measured on my system: curbuf.field 2; delay = 20ms curbuf.field 3; delay = 60ms curbuf.field 2; delay = 20ms curbuf.field 3; delay = 60ms curbuf.field 2; delay = 20ms curbuf.field 3; delay = 60ms ... - VIDIOC_DQBUF fails when using 4 buffers (which VIDIOC_REQBUFS accepts!). Two and three buffers work fine (but with the above wierd latency problem). Looks like it's almost there :-). - Reinoud
