The extended - parameters are described by the meye_params structure. - - -MEYEIOC_QBUF_CAPT - Queue a buffer for capture (the buffers must have been - obtained with a VIDIOCGMBUF call and mmap'ed by the - application). The argument to MEYEIOC_QBUF_CAPT is the - buffer number to queue (or -1 to end capture). The first - call to MEYEIOC_QBUF_CAPT starts the streaming capture. - -MEYEIOC_SYNC - Takes as an argument the buffer number you want to sync. - This ioctl blocks until the buffer is filled and ready - for the application to use. It returns the buffer size. - -MEYEIOC_STILLCAPT and MEYEIOC_STILLJCAPT - Takes a snapshot in an uncompressed or compressed jpeg format. - This ioctl blocks until the snapshot is done and returns (for - jpeg snapshot) the size of the image. The image data is - available from the first mmap'ed buffer. - -Look at the 'motioneye' application code for an actual example. |
