FFMpeg D3D11 decoded image to OpenCV UMat
03/07/2025 by Spuriga
I would like to copy FFMpeg decoded image data to an UMat WITHOUT copiing it to the cpu ram. Is there any way to do it? What if there are two or more GPU card in the PC? I have this code for av_image_copy_to_buffer, works fine, but if I change […]
QQmlContext::setContextProperty alternative
03/07/2025 by kzsnyk
Back to Qt after some time, i can see a lot of changes from Qt5 to Qt6, and especially regarding the way C++ objects may be exposed to QML. From https://doc.qt.io/qt-6/qtqml-cppintegration-contextproperties.html void QQmlContext::setContextProperty(const QString &name, QObject *value) does not seem relevant anymore and best avoided from modularity reasons. Now every […]
Abstract socket binding errno 2
03/07/2025 by jnl
I am trying to bind a Unix abstract socket. However, bind() always returns -1 and the errno is 2 (No such file or directory). #include #include static const char *socket_path = "server-core"; void api_control_thread_func() { int core_fd = socket(AF_UNIX, SOCK_STREAM, 0); // unix domain socket, tcp sockaddr_un core_addr{}; memset(&core_addr, 0, […]

How to convert a std::optional to a std::expected?
03/07/2025 by user2138149
I'm trying to convert a std::optional into a std::expected using a lambda function. The code I have written does not compile. The compiler complains that the monadic functions of std::optional must return another std::optional. Here's my example code, which can be found on Godbolt. godbolt link #include #include #include std::optional […]
nlohmann::json property value directly from stringstream
03/07/2025 by glades
I'd like to directly put the contents of the stringstream buffer into an nlohmann::json object with the least amount of copying possible. So extracting it via ostr.str() is already a no go since this happens in a performance sensitive context and we want to minimize risk on production. Also, afaik […]
