Description

WRITE DESCRIPTION HERE
Hi, i am trying to open and merge the video and audio and feed them into mplayer, this results in no audio being played over the top, the only options that work are the combined vide and audio formats ( -f 18, -f 22) i was tolad i need to use the old lagacy formats when i asked on the gentoo forums (assuming they meant 18 and 22.) is it a bug with youtube-dl that it doesnt merge these audio files before sending them into mplayer?
