• 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')


  


• Xuggler Transcoder error

  4 septembre 2013, par Andrei Baidoc

  I tried to follow the instructions from here : http://www.javacodegeeks.com/2010/05/rtmp-to-rtsp-re-stream-using-wowza-and.html

  All worked fine, Xuggler has been installed with no errors, all tests passed but now when I try to start the transcoder I get this error :

  root@heb1:~# java -jar transcoder-1.0.jar
  
  11:25:28.902 [main] WARN  com.xuggle.ferry.JNILibrary - Failure: library load of library: xuggle; url: /tmp/xuggle/xuggle6615346873936202632.tmp; error: java.lang.UnsatisfiedLinkError: /tmp/xuggle/xuggle6615346873936202632.tmp: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /tmp/xuggle/xuggle6615346873936202632.tmp)

          at com.xuggle.xuggler.Converter.run(Converter.java:1203)
  
          at com.agilio.transcoder.App.main(App.java:34)

  So the transcoder sees the input stream, but for the output it says that it can't find the output format, althow it is send to Xuggler :

  String[] parameters = new String[] { "--acodec", "libfaac", "--vcodec",
  
                      "libx264", "--vpreset",
  
                      "/usr/local/xuggler/share/ffmpeg/libx264-ultrafast.ffpreset",
  
                      inputStream, outputStream };
