• C# (discord music bot) Youtube to mp3 api with ffmpeg

  4 octobre 2017, par Greg Varadi

  Ok, so i have made a discord music bot before with youtube-dl in C#. But I don’t like it because it’s very slow. It has to download the song and then stream it using ffmpeg to discord. I don’t know but I think there is a quicker way.

  So, i decided to use a youtube to mp3 api to get a mp3 as quick as possible, but it won’t work. I mean I found an api that worked, but it’s the worst api I ever seen. This is the api : http://www.convertmp3.io/api/ . Sometimes doesn’t give the mp3, just a link to a download page that doesn’t work.

  I’m still searching for an api. Last time I found this :
  http://www.yt-mp3.com/fetch?v=VIDEO-ID&apikey=1234567
  This is for me the best. But ffmpeg doesn’t recognize the mp3. And I don’t know why because I can’t see any difference beetween them. Of course it’s probably something different but I can’t see what. And I don’t even know that ffmpeg will recognize any of these api’s mp3 files, but it’s working with this convertmp3.io api.

  So, my question is, is there someone who did something like this or someone who can give me advice ?

  By the way, I want something that is as quick as oxyl- or hime bot. And I know that using apis for getting mp3 from youtube videos is not by all means the most legal thing, because the copyright and stuff, but yeah... This is the only way, I think.

• FFMPEG. Concatenate videos with a intro and music

  12 juillet 2019, par Micky

  I’m trying to merge videos with an intro and a background music.

  The intro.flv is a short file with video and audio.
  The other videos are without audio.
  ambientmusic.mp3 is audio to add to subsequent videos.
  A short fade for each file.

  ffmpeg -i intro.flv -i 0.mp4 -i 1.mp4 -i 2.mp4 -i ambientmusic.mp3 -filter_complex "[0] fade = in: 0: 25 [v0]; [1] fade = in: 0:25 [v1]; [2] fade = in: 0: 25 [v2]; [3] fade = in: 0: 25 [v3]; [v0] [v1] [v2] [v3] concat = 4 [v] "-map" [v] "-map a ./output/final.mp4

  Unfortunately the code only loads the first audio. Same result as

  -map 0: a

  If I use this instead it loads ambientmusic.mp3 on the whole video.

  -map 4: a

  But I’d like the audio of the Intro followed by the ambientmusic.mp3

  -map 0: a -map 4: a

What can I do ?

  


  I'm sorry my english is bad.
