Video quality is low.

[MdTalhaZubayer]

I think you should use the video quality as 137/136/135 and merge the audio 140 using "+". like this youtube-dl -f 137+140 url . Please try it hope it will work. or use youtube-dl -F url to get list of all available video formats. I have tried it with npm run build by changing the downloadYoutube.js code

[error]: ERROR: Command failed with exit code 1: C:\udacimak-master\node_modules\youtube-dl\bin\youtube-dl.exe --dump-json -f best 137+140 --encoding utf8 http://www.youtube.com/watch?v=hVwUijsLKzw

don't know how to remove this -f "best", have a try and help me to download the videos at 1080p or 720p.

Thanks!

I tried your approach directly with youtube-dl:

(venv) λ youtube-dl g8b5kgxzUfQ -f 137+140

You can see the WARNING says that in order for youtube-dl to merge video and audio files together, ffmpeg or avconv needs to be installed on the local machine.

I would do it if no extra stuff that is required to be installed, but looks like there are though.

check them!

I have an idea but in this method, we have to download audio and video separately and merge them when the download is finished.like this -f 137 in the first round and -f 140 in the second round and safe all the path of the mp4 videos and mp4a audio in a json file and then run the ffmeg to merge the mp4 and mp4a .... with this command ffmpeg -i vidoefilepath.mp4 -i audiofilepath.m4a -c copy videoname.mp4

Is there a way to choose video quality while downloading a nanodegree? I don't want to download them in 720p

do a version that supports that, please. I'm okay with the extra requirements.
