• download youtube video as audio file, with URL in filename, to a specific output directory

  9 octobre 2018, par thanks_in_advance

  I do this to download a video as an audio file (mp3), with the video’s youtube URL (URI actually) in the audio file’s filename (I like having the URI in the filename because it helps me identify which video I grabbed the audio from) :

  youtube-dl --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the file downloads to the same directory that contains youtube-dl.exe

  I do this to download a youtube video as an audio file (mp3) to a specific output directory :

  youtube-dl -o "C:\Documents\Downloads\%(title)s.%(ext)s" --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the downloaded audio file’s filename doesn’t contain the youtube video’s URI.

  My Question : How can I combine the above 2 commands such that the downloaded audio file doesn’t have either of the cons mentioned above ?

  Here’s the video information :

• How/Where to place the FFMPEG `-legacy_icecast 1` option to only affect one of two Icecast outputs ? (using tee muxer option)

  4 juin 2020, par jzvi12

  I have an FFMPEG command which was able to send an RTMP live feed to 2 different icecast radio stations :

  



  command 1 (in prod ; 1 of 2 failing) :

  



  /home/ubuntu/encoder/bin/ffmpeg -i rtmp://127.0.0.1:1935/app/live -vn -c:a mp3 -ac 2 -b:a 64k -ar 44100 -f tee -map 0 "[f=mp3:onfail=ignore]icecast://source:password@liquidsoap:8000/live|[f=mp3:onfail=ignore]icecast://source:password@fluoz.zeno.fm:80/live"


  



  I would get the following FFMPEG error when running above command 1 :

  



  [tee @ 0x562fffd24bc0] Slave '[f=mp3:onfail=ignore]icecast://source:password@fluoz.zeno.fm:80/live': error opening: End of file
[tee @ 0x562fffd24bc0] Slave muxer #1 failed: End of file, continuing with 1/2 slaves.


  



  It was working fine until these days when one of them (fluoz.zeno.fm:80/live) stopped working and I think Zeno upgraded their Icecast servers from v1 (legacy) to v2. Why ? because when I was doing individual testing to the Zeno icecast server, I realized that it worked fine when I added the -legacy_icecast 1 option

  



  command 2 (testing to Zeno only w/ -legacy_icecast 1 option) :

  



  /home/ubuntu/encoder/bin/ffmpeg -i rtmp://127.0.0.1:1935/app/live -vn -c:a mp3 -ac 2 -b:a 64k -ar 44100 -legacy_icecast 1 -f mp3 icecast://source:password@fluoz.zeno.fm:80/live


  



  QUESTION :

  



  How can I use the command 1 above to still send to both icecast servers but having the -legacy_icecast 1 option to only affect the zeno icecast server and not the liquidsoap icecast server ? I want to avoid running 2 separate instances of ffmpeg at all cost in order to save system resources and bandwidth.

  



  The reason I ask this question is because I tried adding the -legacy_icecast 1 option to the command 1 (that one that sends to both) by placing it right before the ...-f tee... option, but it still didn't work to send to Zeno icecast server which failed (the liquidsoap icecast server kept running fine). It seems to only work fine when I use command 2 (above) when not using the tee muxer option.

  



  Is there a tricky way to place that -legacy_icecast 1 option within the tee muxer option ??
