So this (and I assume every other solution people have mentioned) are using youtube-dl -- which means the chromecast is playing a stream from the device initiating the cast.<p>When I cast from my Android phone to a cast receiver, my understanding is it's basically sending the URL to the receiver and my phone is no longer involved, other than as a remote to control position. (And frustratingly, I find my phone will often get disconnected even though the video is still playing, so I have to spend several seconds waiting or forcing it to reconnect to be able to pause/stop).<p>What's the difference between these two modes? Is there something preventing the URL method from working, or is there a reason it's preferable to download + stream?
