Thank you for the information. I've updated the SVN inside the src folder, I have configured again BCI2000 with CMake and compiled again my application module. Now, no errors appear and the video is correctly played!
Thanks a million for your help
I've only one more question: it it possible to have more than one application window within the same application module?
Thank you

Great that it works for you now. And thanks for reporting the issue!
And yes, you can have any number of windows in the application module. By default, they all have the same coordinates, so make sure to adjust them under Config->Application-><WindowName>WindowCoordinates.
Here is a code example how to use multiple windows:
MyTask.h:
Code: Select all
...
ApplicationWindow &mrWindow, &mrWindow2;
class VideoPlayer* mpVideoPlayer, *mpVideoPlayer2;
...
MyTask.cpp:
Code: Select all
MyTask::MyTask()
: mrWindow(Window()), mrWindow2(Window("Second")),
mpVideoPlayer(nullptr), mpVideoPlayer2(nullptr)
{
mpVideoPlayer = new VideoPlayer(mrWindow);
mpVideoPlayer2 = new VideoPlayer(mrWindow2);
}
void MyTask::OnInitialize(const SignalProperties & /*Input*/)
{
mrWindow.Show();
GUI::Rect rect{ 0.5, 0.7, 0.8, 0.5 };
mpVideoPlayer->SetObjectRect(rect);
mpVideoPlayer->SetFile("video/Test_NTSC.mp4");
if (!mpVideoPlayer->IsOpen())
bcierr << mpVideoPlayer->Error();
mpVideoPlayer->SetScalingMode(GUI::ScalingMode::AdjustHeight);
mpVideoPlayer->Show();
mpVideoPlayer->Play();
mrWindow2.Show();
mpVideoPlayer2->SetScalingMode(GUI::ScalingMode::AdjustHeight);
GUI::Rect rect2{ 0, 0.5, 1, 0.5 };
mpVideoPlayer2->SetObjectRect(rect2);
mpVideoPlayer2->SetFile("video/Test_PAL_HD.mp4");
if (!mpVideoPlayer2->IsOpen())
bcierr << mpVideoPlayer2->Error();
mpVideoPlayer2->Show();
mpVideoPlayer2->Play();
}
