feinerer b0c69ca889 Initialize v4l2_requestbuffers for better libv4l compatibility ... The VIDIOC_REQBUFS ioctl requires a v4l2_requestbuffers struct with the members count, type, and memory. In the past only count was set as the uvideo(4) kernel driver, via uvideo_reqbufs(), is ignoring both struct members type and memory (pointed out by mpi@). However, using video(1) with libv4l (LD_PRELOAD=/usr/local/lib/v4l2convert.so video) yields "mmap: Invalid argument" as libv4l inspects the type and memory struct members and fails if memory != V4L2_MEMORY_MMAP. Full initialization fixes libv4l usage which allows us to view video encodings not directly supported by video(1), e.g., MJPEG, as libv4l can convert encodings on the fly.
