Method 1: Use Browser Developer Tools (No Software Required)
Before using any third-party tools, always check if the website or video player itself provides a download function. Look for a visible "Download," "Save," or an arrow icon usually located near the video controls. On mobile browsers, you might need to tap the video and look for a "⋮" (more) menu to find a download option.
The site might be blocking direct stream access. Try using OBS Studio instead, as it records what is displayed on the screen rather than downloading the source directly.
