No, they don't apply (AFAICT). Try v4l2-ctl --verbose --streamon v4l2-ctl --verbose --streamoff and you should see that you're getting EINVAL back for both. > I would guess they should either turn off the mpeg encoder or decoder > stream > But they do not seem to. They don't refer to that "stream" (between encoder/decoder and host). They refer to streaming between the user-space application and kernel with mapped memory or user memory buffers, instead of read()/write()/poll() I/O. See Chapter 3 of the V4L2 API document for more details: http://www.linuxtv.org/downloads/video4linux/API/V4L2_API/v4l2spec/v4l2.pdf My kernel's version of the ivtv driver doesn't support the VIDIOC_STREAMON/VIDIOC_STREAMOFF ioctl()s, so it doesn't use those I/O methods.
