Ask the ffmpeg developers :-) Sorry, but I can't help you there, I have no experience with ffmpeg. Best regards, Laurent Pinchart
Hi again :) As long as bandwidth is the only problem I should also be able to fix this problem by lowering the frames-per-second, right? When run in normal 24 fps-mode,ffmpeg outputs this line (among others): Stream #0.0: Video: rawvideo, yuv422, 1024x576, 235929 kb/s, 25.00 fps(r) Yet if I run the recording with only 5 fps I get this: Stream #0.0: Video: rawvideo, yuv422, 1024x576, 47185 kb/s, 5.00 fps(r) If I am able to use 235929 in one go I should be able to record 2 times 47185 easily, right? I keep getting the same error as before: ioctl(VIDIOC_STREAMON): No space left on device Could not find video grab device Haven't been able to find a way of setting capture method to MJPEG instead of YUV, but I'll keep looking although right now I'm not sure it'll help at all, seems there is something else causing this problem.
