CHALLENGE Muz/gyts script fix/alternatives Yad script

[VastOne]

Muz is my favorite alias and script that we have... It basically calls gyts and converts what you search for from youtube into an mp3

For the last several months the gyts script has been broken due to this line changing somehow at youtube

lynx -dump -listonly http://www.youtube.com/results?search_query=

This is the entire gyts script

This is another script I have found that works perfectly using wget and whatever your search query is ...

youtube-dl-mp3

#!/bin/bash

url=$1
path=$2

TMP_FILE="youtube-mp3-$RANDOM.tmp"

youtube-dl --ignore-errors --get-title --get-url --get-filename "$url" > $TMP_FILE 2> "/tmp/$TMP_FILE.err"

exec 42< $TMP_FILE

while read video_title <&42 ; do
  read video_url <&42
  read video_filename <&42
  wget "$video_url" -O "$video_filename"
  ffmpeg -i "$video_filename" "$video_filename.wav"
  if [ -z "$path" ]; then
    lame -b 320 "$video_filename.wav" "$video_title.mp3"
  else
    lame -b 320 "$video_filename.wav" "$path/$video_title.mp3"
  fi
  rm -f "$video_filename" "$video_filename.wav"
done

exec 42<&-
rm -f $TMP_FILE

It works like this

youtube-dl-mp3 "the youtube url of the video you want to convert"

We have one of three options (as I see it anyway, please add more if you see fit)

1 - Fix the query string in the original gyts so that it is recognized again

2 - Change the gyts script to use wget instead of lynx ... we could even use the wget code from the second script ... need bash understanding help here (and wget) ... this is my favorite possible solution

3 - Just make a new Yad front end for the second script.. I like this idea but it eliminates a search function...  I would like to see this done anyway so if you Yad experts are willing ...

Call to arms for you that love this.. this is where I want to be as transparent as possible.. I could muddle along a figure this out eventually, but I do not want to!

Very interesting script. It can be used without the mp3 conversion part too. And it should be easily tweaked to download into other (better) audio formats than mp3 (or video formats) with just ffmpeg. So cool. Thanks for sharing, VastOne.

Wish I could help with the other part. I guess lynx is not needed at all. In the end the script is using youtube-dl,  ffmpeg and lame too. Only the browsing part needs to be modified to use anything else instead of lynx, IMO. My bash scripting abilities are almost null, but I'll give it a go anyway.

^ We really do not need anything other than the new one.. I think I will just change that to muz on the next ISO build.. I would like to see it with a yad front end..

I have discovered this about the youtube-dl-mp3 script...

Most everything on YouTube now creates a playlist ... I played a single album of Liquid Mind and in turn it created a Liquid Mind playlist and when I clicked on it got this url that had 10 albums on it

By running that url with youtube-dl-mp3 in " "  it downloaded all 10 albums and converted each to mp3...

Not a bad script at all
