Specifying the frame rate you want capture might help in this case[1]. For bttv this would'nt make a big difference, but with USB hardware which might have to post-process video data (uncompress due to the limited bus bandwidth) this should help a bit as you avoid processing data which will be dropped by the application anyway ... > drop the last or the oldest frame? Whichever is less work for the driver, i.e. probably drop the last one. Gerd [1] Hmm, no v4l2 ioctl for this yet. Add one? -- Gerd Knorr <kraxel@xxxxxxxxxxx> -- SuSE Labs, Außenstelle Berlin
