hi,
I have implemented support for V4L2_MEMORY_USERPTR buffers in gstreamers
v4l2src [1]. This allows to request shared memory buffers from xvideo,
capture into those and therefore save a memcpy. This works great with
the v4l2 driver on our embedded device.
When I was testing this on my desktop,

Sorry for a non-kernel question, but I'd like to get some suggestions
on video recording and editing software, please.
If it matters, this is mostly for recording editing sports events

When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the
v4l2_buffer buffer gets unmodified on drivers like uvc (well, only
bytesused field is modified). Then some apps like gstreamer are reusing
the same buffer later to call munmap (eg passing the buffer
