You can merge the video and audio of two formats into a single file using -f <video-for- mat>+<audio-format> (requires ffmpeg or avconv installed), for example -f bestvideo+bestaudio will download the best video-only format, the best audio-only format and mux them together with ffm- peg/avconv. but the most important bit is... Note that if you use youtube-dl to stream to stdout (and most likely to pipe it to your media player then), i.e. you explicitly specify output template as -o -, youtube-dl still uses -f best format selection in order to start content delivery immediately to your player and not to wait until bestvideo and bestaudio are downloaded and muxed. hope this helps =] cheers > On Sep 4, 2017, at 7:38 05AM, Moritz Barsnick <[email protected]> wrote: > > On Wed, Aug 23, 2017 at 21:16:57 -0700, johnsmithbin wrote: >> Hello. >> I want livestream from youtube video link.
