  • Using ffmpeg with Python 2.7

    1er juillet 2015, par suffa

    I have been trying to install pyffmpeg in Python 2.7 unsuccessfully. I found a package for Python 2.6, but I can’t get it to work. So, I have been mulling around with 2.7. I’ve seen previous post from others on this site, but they have not helped. Does anyone have experience with this. Ultimately, I want to develop an wxPython app that converts video formats. Thanks

    Code that I ultimately wrote that worked for me (very rudimentary, but it works ....) :

    import wx
    import os
    import sys
    import time
    import datetime
    from wx.lib.delayedresult import startWorker

           menu2.Append(5, "&.mpg to dvd", ".mpg to dvd")

  • Spaces in variable

    13 avril 2012, par Roger

    I am facing some problems with spaces in variables :

    ALBUM=' -metadata album="Peregrinações Alheias"'

    This command :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k "$ALBUM" -y $OUT

    Returns :

    Unable to find a suitable output format for ' -metadata album="Peregrinações Alheias"'

    And if I take out the "" from the variable :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $ALBUM -y $OUT

    Returns :

    Unable to find a suitable output format for 'Alheias"'

    And I am sure I am missing something in the bash sintax...


    UPDATE :

    So it looks that the matter is not with spaces but with the "-metadata" argument...

    The problem is that I have many metadata and I'd like to put them in just one variable. Like this :

    META=' -metadata album="Peregrinações" -metadata title="Passeio ao PETAR" -metadata author="Rogério Madureira" -metadata date="2012" -metadata description="Áudio de um passeio ao PETAR" -metadata comment="Áudio capturado com TACAM DR-07MKII e Foto capturada com Canon PowerShot S5IS" '

    And then :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $META -y $OUT

  • FFMPEG Video encoding error

    13 juin 2012, par user1290051

    I am trying to encode my video using ffmpeg. I have taken output of each frame as a separate image and then I'm joining them into a video using ffmpeg. I compiled ffmpeg from source.
    This is the command I used and the errors I keep running into !
