Hi guys,
I'm new to this forum, so please forgive me if this is not the right place for this topic:
After a not-at-all-simple session to compile the current avidemux 2.6 git head (commit 9aeafced3fcf014fdd0919d38341693447fcea50) under CentOS 6, I finally succeeded to get a workable executable (for the Qt4 version, GTK on CentOS is pretty incompatible with the version avidemux 2.6 expects, while Qt4 4.6.2 required only a few adjustments to the code).
The first thing I usually do when editing files is to press "Ctrl+O" for opening a file, but this caused just the error message QAction::eventFilter: Ambiguous shortcut overload: Ctrl+O
Opening a file from the menu worked fine.
I found two places where "Ctrl+O" was mentioned: ./avidemux/common/ADM_commonUI/myOwnMenu.h:35: {MENU_ACTION,"Open", NULL,ACT_OPEN_VIDEO, MKICON(fileopen), "Ctrl+O"},
./buildQt4/ADM_userInterfacesQT4/ADM_gui/ui_gui2.h:1065: actionOpen->setShortcut(QApplication::translate("MainWindow", "Ctrl+O", 0, QApplication::UnicodeUTF8));
Commenting out the second one, ui_gui2.h:1065, resolved this issue for me - CTRL+O now works.
The file I changed seems to be generated somewhen within the build procedure, so I hope you can fix this "in the right place", instead.
Edit: I found that the same problem also applies to Ctrl+S - "QAction::eventFilter: Ambiguous shortcut overload: Ctrl+S", and the same fix (commenting out ./ADM_userInterfacesQT4/ADM_gui/ui_gui2.h:1073) worked for me.
(I made other bug observations, but I guess it's better to report only one bug per posting, so I'll open another one for the next bug.)
