I am trying to use v4l2 with shared memory.
userptr mode uses queue , where queue us limited to hold maximum 32 buffers.
to overcome the limitation,i thought about using r\w mode.
the idea is to manage a private queue with 300 pointers to buffers.
every time i call v4l2 \ read, i will send it a pointer to the next buffer
question is: why is userptr considered less managable than userptr ?
(documantioation mentioned time stamps, but i i not sure what it means)
