Ich versuche, einen gstreamer Bash-Skript zu C++ Code, y umcodiert werden, aber ich bin nicht in der Lage de debuggin melden Sie sich in eine Datei speichernGStreamer Debug-Pipeline C++
Dies ist mein Code

}Ich benutze gstreamer-1.0-Bibliothek und ich habe gesehen, dass ich GST_DEBUG_FILE verwenden muss, aber ich weiß nicht, wie diese Funktionen von C++ aufrufen.
Danke für die Hilfe!
