• How do you get amplitude of audio file in Android before you play it ?

  30 août 2020, par McMillanMe

  I know we can easily do it when we record it (several ways, actually). But how are we going about getting an amplitude graph from an mp3/ogg file ?

  



  As it is now, I see two options :
 1. Quickly play it & construct it while its playing
 2. Try to do it with ffmpeg (but I really don't want to do NDK)

  



  Are there any other options beside these ? Thank you

  


• How to play video files (mov, mp4, ts etc etc) in a web page

  5 juillet 2021, par Dierre

  I have a question about playing several video files in an intranet page.

  


  The page is really simple, there is a list with videos ordered by name and clicking one of them, it starts in the page inside video tag using JS to replace the source.

  


  It works with MP4 files but for example mov and other files do not work or play only audio.
I understood this is a normal problem of browsers that does not support all video types, so the question is :
Is there a way to play them without convert all files to mp4 ?

  


  I have access to the linux server with apache web server, ffmpeg is installed I can install other software if necessary (streaming server ? file streaming ? I'm not an expert) I am not interested to live events.

  


  Does anyone have any idea if it is possible to solve it ?

  


  Thanks in advance

• Discord.py rewrite play audio from youtube into voice chat

  23 avril 2021, par John Henry 5

  I'm trying to get a bot that can join a voice chat on command and then play some audio extracted from a youtube video. I don't know how to do this and all the code that I've gotten does not seem to work. Does anyone know how to do this ?

  


  @client.command() async def play(ctx):
   channel = ctx.message.author.voice.channel
   voice_client = await channel.connect()

   opts = {'format': 'bestaudio'}
   FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 - 
   reconnect_delay_max 5', 'options': '-vn'}

   with youtube_dl.YoutubeDL(opts) as ydl:
      song_info = ydl.extract_info('video', download=False)
      URL = song_info['formats'][0]['url']
   
   voice_client.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
