• 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 Error : Pattern type 'glob' was selected but globbing is not support ed by this libavformat build

  14 septembre 2017, par Aryan Naim

  I’m trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"

  Example parameters i used :

  frame duration  = 2 secs
  
  frame rate      = 30  fps
  
  encoder         = libx264 (mpeg)
  
  input pattern   = "*.jpg"
  
  output pattern  = video.mp4

  Based on ffmpeg wiki instructions at (https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images), I issued this command :

  ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4

  But I’m getting this error :

  [image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not 
  
  supported by this libavformat build *.jpg: Function not implemented

  Which probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (ffmpeg-20150702-git-03b2b40-win32-static).

  How can I choose a group of files using pattern matching using ffmpeg ?

• Still can't install pygame on ubuntu

  1er octobre 2016, par brotheroflogan

  I’ve tried three different ways. The most recent was following instructions here : http://www.pygame.org/wiki/CompileUbuntu

  But when I type in the first line

  sudo apt-get install mercurial python-dev python-numpy ffmpeg \

  I am told that

  E: Package 'ffmpeg' has no installation candidate.

  I continue on with the instructions and I am later told that some of the dependencies are missing (even though those are the ones I had attempted to install moments ago).

  Then when I put in

  sudo python3 setup.py install

  it tells me

  src/_pygame.h:80:20: fatal error: Python.h: No such file or directory
  
   #include 
  
                      ^
  
  compilation terminated.
