Well, it used to be simple, but alas... In this - module, 3 buffers schemes are used to get the data from the USB bus to - the user program. The first scheme involves the ISO buffers (called thus - since they transport ISO data from the USB controller), and not really - interesting. Suffices to say the data from this buffer is quickly - gathered in an interrupt handler (pwc_isoc_handler) and placed into the - frame buffer. - - The frame buffer is the second scheme, and is the central element here. - It collects the data from a single frame from the camera (hence, the - name). Frames are delimited by the USB camera with a short USB packet, - so that's easy to detect. The frame buffers form a list that is filled - by the camera+USB controller and drained by the user process through - either read() or mmap(). - - The image buffer is the third scheme, in which frames are decompressed - and converted into planar format. For mmap() there is more than - one image buffer available. - - The frame buffers provide the image buffering. In case the user process - is a bit slow, this introduces lag and some undesired side-effects. - The problem arises when the frame buffer is full. I used to drop the last - frame, which makes the data in the queue stale very quickly. But dropping - the frame at the head of the queue proved to be a litte bit more difficult. - I tried a circular linked scheme, but this introduced more problems than - it solved. - - Because filling and draining are completely asynchronous processes, this - requires some fiddling with pointers and mutexes. - - Eventually, I came up with a system with 2 lists: an 'empty' frame list - and a 'full' frame list: - * Initially, all frame buffers but one are on the 'empty' list; the one - remaining buffer is our initial fill frame. - * If a frame is needed for filling, we try to take it from the 'empty' - list, unless that list is empty, in which case we take the buffer at - the head of the 'full' list. - * When our fill buffer has been filled, it is appended to the 'full' - list. - * If a frame is needed by read() or mmap(), it is taken from the head of - the 'full' list, handled, and then appended to the 'empty' list. If no - buffer is present on the 'full' list, we wait. - The advantage is that the buffer that is currently being decompressed/ - converted, is on neither list, and thus not in our way (any other scheme - I tried had the problem of old data lingering in the queue). - - Whatever strategy you choose, it always remains a tradeoff: with more - frame buffers the chances of a missed frame are reduced. On the other - hand, on slower machines it introduces lag because the queue will - always be full. - */ - -/** - \brief Find next frame buffer to fill.
