So your 10 minute video could have 2 minutes of 1280x720 content and 8 minutes of 480x360 content - it's quite complex to take all those pieces (before they're deleted by Flash as they're no longer needed) and recompose them in a single video file with audio included. The Flash plugin starts downloading the audio and then depending on your internet connection, it switches between video formats and syncs the video file to the audio file in real time. For one, an extension runs in the browser page as a script, while the video is downloaded by Flash plugin, which is like a separate universe - the script running on the page could probably determine the address from where Flash downloads the video but can't know where Flash saves on disk the video, if it even saves it to disk.Īlso, lately Youtube uses a new approach to playing video, they have several formats of video and the audio is separate. I understand what you probably mean, you want to have an option to 'recover' somehow the video after you watched it. or you can just move away to another Youtube page. You can select the format you want and start the video download, then you can simply close that youtube page so that the embedded player won't buffer the video. The extension I linked to adds a download button under the video that also allows you to select the format and tells you the file size.
