Velikost livestream velikost rámu z fotoaparátu Pyqt5

Vytvořil jsem tři okna pomocí pyqt5. Jsou jak je uvedeno níže.

1. Hlavní Okno

Když tlačítko start je klikli, další se otevře okno, které je jak je uvedeno níže.

2. Prostřední Okno

Toto okno přijímá streaming link pro připojení fotoaparátu. Pro normální usb kamery je '0'. Při 0 je dána jako vstup, další okno se otevře.

3.Výstupní Okno

Problém je, že jsem čelí, je, že nejsem schopen změnit velikost velikost výstupního rámu, i když jsem schopen změnit velikost velikost obrazovky.

** Kód na poslední okno je připojen níže,**
