https://github.com/rg3/youtube-dl/issues/4886#issuecomment-94792491  force mp4 highest res and best audio

example
this version is throttled by google

youtube-dl --yes-playlist -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/mp4'  'https://www.youtube.com/watch?v=CaCcOwJPytQ&list=PLX2gX-ftPVXU3oUFNATxGXY90AULiqnWT' 

try this one for higher speeds without throttling.

youtube-dl --yes-playlist -f 'bestvideo[ext=mp4]+audio[ext=m4a]/mp4'  'https://www.youtube.com/watch?v=CaCcOwJPytQ&list=PLX2gX-ftPVXU3oUFNATxGXY90AULiqnWT'
