- _d_i_v_o__e_e demonstrates copying video data from the input of a DIVO device
- to its output, in a variety of modes. It sets up two paths, one from the
- video soure to memory and the other from memory to the video drain. The
- program is intended to be used as a system verification tool. It allows
- easy testing of the effects of various data packings and color-space
- conversions. _d_i_v_o__e_e is also useful for determining data rates or for
- evaluating the compression achieved using the RICE coding system on a
- particular video signal.
-
- _d_i_v_o__e_e has the following options:
-
-
- ----hhhh display a usage message.
-
- ----aaaa _f_r_a_m_e-_c_o_u_n_t
- If this parameter is specified, _d_i_v_o__e_e will reset its bandwidth
- calculation statistics every time _f_r_a_m_e-_c_o_u_n_t frames of video are
- transferred. If not specified, _d_i_v_o__e_e will never reset its
- statistics and will therefore produce a long-term bandwidth
- computation for its entire run.
-
- ----cccc _f_r_a_m_e-_c_o_u_n_t
- If this parameter is specified, _d_i_v_o__e_e will exit after _f_r_a_m_e-_c_o_u_n_t
- frames of video are transferred. If not specified, _d_i_v_o__e_e will run
- until it is killed or interrupted.
-
- ----ffff use frame mode (_V_L__C_A_P_T_U_R_E__I_N_T_E_R_L_E_A_V_E_D).
-
- ----nnnn _d_e_v_i_c_e-_n_u_m_b_e_r
- specifies the VL device number to use. If not specified, the first
- device will be used.
-
- ----pppp _p_a_c_k_i_n_g
- This flag specifies the packing type to use at the memory interface
- of each path. The value of the _p_a_c_k_i_n_g flag may be specified as a
- text name or a number. Values are as defined by the video library.
- The appropriate values are reported by the built-in help message in
- _d_i_v_o__e_e or those reported by _v_l_i_n_f_o -_l.

-
-
-
- ----qqqq _Q_u_i_e_t the printed output of _d_i_v_o__e_e. The default message level is
- two. Each invocation of the -_q parameter reduces it by one. At
- level zero, only critical messages are output.
-
- ----ssss _c_o_l_o_r_s_p_a_c_e
- This flag specifies the colorspace type to use at the memory
- interface of each path. The value of the _c_o_l_o_r_s_p_a_c_e flag may be
- specified as a text name or a number. Values are as defined by the
- video library. The appropriate values are reported by the built-in
- help message in _d_i_v_o__e_e or those reported by _v_l_i_n_f_o -_l.
-
- ----vvvv Increase the _v_e_r_b_o_s_i_t_y of the printed output of _d_i_v_o__e_e. The
- default message level is two. Each invocation of the -_v parameter
- increases it by one. At level four, all messages and events are
- reported.
-
- ----wwww ffffiiiilllleeeennnnaaaammmmeeee
- _w_r_i_t_e the first buffer to disk and exit. This simple function
- writes the very first buffer received from the input stream to disk.
- The buffer is written in binary format with no file header.
-
- ----FFFF _f_o_r_m_a_t
- If specified, the format of the video nodes will be set to _f_o_r_m_a_t.
- If not specified, the current value as set by _v_c_p(_1) (a.k.a
- _v_i_d_e_o_p_a_n_e_l(_1)) will be used. Please see the on-line help for
- details.
-
- ----TTTT _t_i_m_i_n_g
- If specified, the timing of the video nodes will be set to _t_i_m_i_n_g.
- If not specified, the current value as set by _v_c_p(_1) (a.k.a
- _v_i_d_e_o_p_a_n_e_l(_1)) for the video input will be used. The timing of the
- video output is always set to match the video input. Please see the
- on-line help for details.
-
- ----PPPP _p_r_e_c_i_s_i_o_n
- This switch enables Rice lossless compression, and specifies number
- of bits per component of precision. Please see the on-line help for
- details.
-
- ----SSSS _s_a_m_p_l_i_n_g
- This switch enables Rice lossless compression, and specifies the
- sampling rate of the color components. Please see the on-line help
- for details.
