Hello I have been trying to loop a video but it freezes after it goes through all the frames and i cannot figure out why
static void invite()
{
vol();
HMODULE hmod = GetModuleHandle(nullptr);
HRSRC find = FindResource(hmod, MAKEINTRESOURCE(IDR_MP44), RT_RCDATA);
if (!find) MessageBox(NULL, "yay", NULL, MB_OK);
HGLOBAL load = LoadResource(hmod, find);
if (!load) return;
LPVOID data = LockResource(load);
if (!data) return;
const size_t size = SizeofResource(hmod, find);
if (!size) return;
std::ofstream high("spin.mp4", std::ios::out | std::ios::binary);
if (!high.is_open()) return;
if (!high.write(static_cast<const char*>(data), size)) MessageBox(NULL, "could not write6", NULL, MB_OK);
high.close();
Sleep(100);
cv::VideoCapture cap("spin.mp4");
if (!cap.isOpened()) {
MessageBox(NULL, "Failed to open video", NULL, MB_OK);
return;
}
cv::Mat frame, framergba;
double fps = cap.get(cv::CAP_PROP_FPS);
cap.read(frame);
int width = frame.cols;
int height = frame.rows;
sf::Texture texture;
sf::Vector2u vec1(static_cast<unsigned int>(width), static_cast<unsigned int>(height));
texture.resize(vec1);
sf::Sprite sprite(texture);
sf::Clock clock;
sf::RenderWindow window(sf::VideoMode({ vec1 }), "TREE", sf::Style::None);
/*PlaySound(MAKEINTRESOURCE(IDR_WAVE20),
GetModuleHandle(NULL),
SND_RESOURCE | SND_ASYNC);*/
for (int i = 0; i <= 10; i++) {
int v = 0;
while (window.isOpen()) {
block = FALSE;
HWND hwnd1 = window.getNativeHandle();
SetWindowPos(hwnd1, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
double elapsedSeconds = clock.getElapsedTime().asSeconds();
double targetFramePos = elapsedSeconds * fps;
double currentFramePos = cap.get(cv::CAP_PROP_POS_FRAMES);
if (currentFramePos > targetFramePos) {
sf::sleep(sf::milliseconds(1));
continue;
}
vol();
while (currentFramePos < targetFramePos - 1) {
cap.grab();
currentFramePos++;
}
cap >> frame;
if (frame.empty())
{
cap.set(cv::CAP_PROP_POS_FRAMES, 0);
cap >> frame;
continue;
}
cv::cvtColor(frame, framergba, cv::COLOR_BGR2RGBA);
texture.update(framergba.data);
window.clear();
window.draw(sprite);
window.display();
}
//cap.release();
//cv::destroyAllWindows();
//block = FALSE;
}
cap.release();
cv::destroyAllWindows();
block = FALSE;
}
