4. _K_n_o_w_n__B_u_g_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
This chapter lists known bugs and workarounds for SGImeeting
SGItools Plugins at the time of release.
4.1 _K_n_o_w_n__B_u_g_s
SGImeeting SGItools Plugins have the following known bugs:
_V_i_d_e_o _c_a_p_t_u_r_e _o_n _t_h_e _D_I_V_O _a_n_d _E_V_1 _C_a_r_d_s
Video capture does not work on an Onyx2 using a DIVO
Digital Video Card or an Indy using a EV1 Digital Video
Card. You will get an error message or a black screen
if you try to use them. A workaround to this problem
is to run the "_v_i_d_e_o_i_n" executable from the shell and
use screen capture on top of the image. Note: The -z
option changes the image size. For example to get
quarter frame size, enter:
vvvviiiiddddeeeeooooiiiinnnn ----zzzz 1111////4444
_V_i_d_e_o _c_a_p_t_u_r_e _o_n _a_n _O_c_t_a_n_e _u_s_i_n_g _a _P_e_r_s_o_n_a_l _V_i_d_e_o _C_a_r_d
Video capture on an Octane using a Personal Video Card
does not work properly on IRIX 6.5.2 and 6.5.3. You
must upgrade to IRIX 6.5.4 or greater. Also make sure
your VideoPanel is set to camera as your default input.
_S_t_r_e_a_m _p_r_e_e_m_p_t _m_e_s_s_a_g_e
The video preview button is included in the video
capture controls. It uses "_v_i_d_e_o_i_n" to run the
previewer. Occasionally "_v_i_d_e_o_i_n" returns an error
message to the console: "_v_i_d_e_o_i_n: _S_t_r_e_a_m _w_a_s _p_r_e_e_m_p_t_e_d
_b_y _a_n_o_t_h_e_r _P_r_o_g_r_a_m". This error results in the
previewer disappearing prematurely.
_V_i_d_e_o _d_e_v_i_c_e _t_r_a_n_s_f_e_r _e_r_r_o_r_s
If you have more than 2 live video captures running on
a page, you may occasionally see the error message:
"_v_i_d_e_o _d_e_v_i_c_e: _a_n _e_r_r_o_r _o_c_c_u_r_r_e_d _d_u_r_i_n_g _v_i_d_e_o
_t_r_a_n_s_f_e_r." or the Stream preempt message. These errors
- 2 -
occur when the video library becomes overloaded with
requests. You may want to stop one of the video
captures to avoid these errors and contention in the
library.
_W_h_i_t_e_b_o_a_r_d _r_e_d_r_a_w_s _s_l_o_w_l_y _o_n _O_n_y_x_2
When an Onyx2 whiteboard receives live video captures
during a conference, it redraws itself slower than
expected.
_S_G_I_m_e_e_t_i_n_g _1._0, _S_u_n_F_o_r_u_m _c_o_m_p_a_t_i_b_i_l_i_t_y
Due to a bug in the SGImeeting 1.0 and SunForum 1.0
products, the screen and video plugins will only send
the initial image, and will not update when the source
image changes. This problem has been fixed in
SGImeeting 1.1 or later and SunForum 2.0 or later. It
is recommended that all conference participants using
the 1.0 version of SGImeeting or SunForum upgrade to
the later versions as soon as possible.
_S_c_r_e_e_n _c_a_p_t_u_r_e _c_o_n_t_r_o_l_s _h_a_v_e _w_r_o_n_g _c_o_l_o_r_s
When using the screen capture plugin to capture an area
of the screen, you may occasionally see the screen
capture controls appear in the wrong color. The colors
will correct themselves the next time you move the
mouse into the screen capture area.
4.2 _K_n_o_w_n__L_i_m_i_t_a_t_i_o_n_s
_L_i_v_e _S_c_r_e_e_n _a_n_d _V_i_d_e_o _i_m_a_g_e_s _o_n _m_u_l_t_i_p_l_e _p_a_g_e_s
If you insert live screen and video images into more
than one page of the whiteboard, you should be aware
that only images in the page you are currently viewing
will update. If a member of the conference is viewing a
different page than the sender of the live images, they
will not see updating images.
When the receiver of the live images changes to the
- 3 -
same page as the transmitting member, then the images
will begin updating again.
_S_c_r_e_e_n _a_n_d _v_i_d_e_o _p_e_r_f_o_r_m_a_n_c_e
When sending large screen or video images to the
whiteboard, the performance of the user interface may
become poor. The workaround is to either increase the
update delay time for the image, or decrease the size
of the image.
