also, 3 or more displays will not work?
I used Cinelerra with 5 displays and it's works ok. I didn't try Cinelerra with second xserver. Best regards, Andrey вс, 8 янв. 2023 г., 07:41 Andrew Randrianasulu via Cin < [email protected]>:
I tried to test multi-monitor support by firing another, nested X server
Xephyr :1 -screen 1024x768
then Cin displays her windows on either DISPLAY :0 or :1 depend on preferences but I can\t set compositor to just one ...xserver.
I looked into code :)
in cwindowgui.C
CWindowGUI::CWindowGUI(MWindow *mwindow, CWindow *cwindow) : BC_Window(_(PROGRAM_NAME ": Compositor"), mwindow->session->cwindow_x, mwindow->session->cwindow_y, mwindow->session->cwindow_w, mwindow->session->cwindow_h, xS(100), yS(100), 1, 1, 1, BC_WindowBase::get_resources()->bg_color, mwindow->get_cwindow_display())
in mwindow.C
char *MWindow::get_cwindow_display() { char *x11_host = screens < 2 || session->window_config == 0 ? session->a_x11_host : session->b_x11_host; return *x11_host ? x11_host : 0; }
and screens set in
void MWindow::init_preferences() { preferences = new Preferences; preferences->load_defaults(defaults); File::setenv_path("LV2_PATH",preferences->lv2_path, 1); session = new MainSession(this); session->load_defaults(defaults); // set x11_host, screens, window_config screens = session->set_default_x11_host();
so into mainsession.C
// set default x11 host, window_config, return screens int MainSession::set_default_x11_host(int win_config) { if( win_config < 0 ) win_config = window_config; const char *x11_host = win_config!=1 ? a_x11_host : b_x11_host; BC_DisplayInfo display_info(x11_host,0); int screen = display_info.get_screen(); if( screen < 0 && strcmp(a_x11_host, b_x11_host) ) { win_config = win_config==1 ? 0 : 1; x11_host = win_config!=1 ? a_x11_host : b_x11_host; display_info.init_window(x11_host,0); screen = display_info.get_screen(); } if( screen < 0 ) { x11_host = ""; display_info.init_window(x11_host,1); } int screens = 1; if( display_info.get_screen_count() > 1 ) screens = strcmp(a_x11_host, b_x11_host) != 0 ? 2 : 1; window_config = win_config; BC_Window::set_default_x11_host(x11_host); return screens; }
and display_info lives in
guicast/bcdisplayinfo.C and h
in our case in h file
int get_screen() { return scrnum; }
and scrnum set to scrnum = DefaultScreen(display);
in void BC_DisplayInfo::init_window(const char *display_name, int show_error)
so, it seems having two 'x11 hosts" as separate X servers to send Compositor to actually not supported... ? we query number of screens on specific display/host ...
so :0.0 and :0.1 works, while :1.0 and :0.0 not ?
also, 3 or more displays will not work? -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
