• Combining Audio and Video file in python [duplicate]

  8 juin 2020, par yso

  I'm trying to understand how to us ffmpeg to combine video and audio files in python. I want to combine a .avi file and a .wav file to create a final .avi file. Is this the right approach ? I'm confused by the ffmpeg syntax.
Any help would be great.

  



  I was looking through this for help :
https://wiki.libav.org/Snippets/avconv#Combine_audio_and_video_file

  



  import ffmpeg
import subprocess

cmd = 'ffmpeg -i inputvideo.avi -i inputaudio.wav -c:v copy -c:a aac output_video_and audio.avi'
subprocess.call(cmd, shell=True)                                     # "Muxing Done
print('Muxing Done')


  


• [C++][Linux + ffmpeg + h264 + rtsp + client] and [Window + ffmpeg + play video real time + server]

  21 avril 2015, par QuestionGuy

  I have a problem with ffmpeg and I don’t know how to continue. I have 2 computers :

  Client :

  • Run Ubuntu 14.04
  • FFmpeg installed
  • Use c++ language
  • Features : use ffmpeg to encode h264 video data from webcam of client laptop, then real time streaming to server

  Server :

  • Running Windows 7
  • FFmpeg installed
  • Use c++ language (MFC)
  • Features : Get real time data from client and show it on screen.

  I’ve just connected client to server and they can chat text data together, and I don’t have any idea to make real time video work.

  And my questions are :

  1. [Client] How to get video from webcam on laptop (using ffmpeg code), save it to buffer (raw data), encode it and send to server ?

     I use ffmpeg to get video from wc but it save to file. I really don’t want it. Code is :

     ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 output.mkv

  2. [Client] How to get raw data from client, decode it and play it ?

     I have an idea to play it by using directshow in MFC.

• Discord bot : Fix ‘FFMPEG not found’

  14 mars, par Travis Sova

  I want to make my Discord bot join voice chat, but every time I run the command, I get an error message in the log(cmd) saying, FFMPEG not found.

  


  Picture of the error :

  


  

  


  This is the code :

  


  client.on('message', message => {
  // Voice only works in guilds, if the message does not come from a guild,
  // we ignore it
  if (!message.guild) return;

  if (message.content === '/join') {
    // Only try to join the sender's voice channel if they are in one themselves
    if (message.member.voiceChannel) {
      message.member.voiceChannel.join()
        .then(connection => { // Connection is an instance of VoiceConnection
          message.reply('I have successfully connected to the channel!');
        })
        .catch(console.log);
    } else {
      message.reply('You need to join a voice channel first!');
    }
  }
});


  


  this is my package.json file :
