    Wink How to convert a swf video into the avi format

    Recently I watched this video.
    http://nat.org/demos/gtksharp.html

    The problem was I couldn't move the movie forward or backward...
    Very annoying.

    So I had to convert the swf into a avi/flv video.

    I downloaded the video
    Code:
    wget http://nat.org/demos/gtksharp.swf
    Searched for edit.py in the package pyvnc2swf
    Code:
    apt-get install pyvnc2swf
    apt-file search edit.py
    pyvnc2swf: /usr/share/pyvnc2swf/edit.py
    With which I could easily convert the .swf file into a .flv file
    Code:
    /usr/share/pyvnc2swf/edit.py -o output.flv gtksharp.swf

    From that point on, one can use ffmpeg to convert the flv movie into any popular video format, e.g. avi
    Code:
    ffmpeg -i output.flv output.avi

    When I try to use this and run the call /usr/share/pyvnc2swf/edit.py -o RandomB.flv RandomB.swf

    I get this:

    Using pygame 1.9.1release
    Input movie: version=8, size=430x450, framerate=10fps, frames=633, duration=63.3s.
    Output movie size: 430x450
    Scanning source swf file: RandomB.swf...

    File "/usr/share/pyvnc2swf/mp3.py", line 232, in read_mp3file
    assert totalsamples == totalsamples0
    AssertionError


    What should I do to fix this problem?

    I'd say file a bug-report for pyvnc2swf.

    Re: How to convert a swf video into the avi format

    Hi,
    I am trying to convert some swf files to flv in order to be able to edit them using avidemux,since i can open flv files but not swf.
    the problem is that the output is a black screen.
    do you know what might be the problem?

    Re: How to convert a swf video into the avi format

    Hi,

    I am trying to convert a swf file into a flv video. I followed the steps provided by you, and I get a really short (1 or 2 seconds) black video. The original file is like 20 or 30 seconds long.

    I wrote this in the terminal:

    Code:
    /usr/share/pyvnc2swf/edit.py -o my_video.flv my_file.swf
    What did I do wrong? Thanks!
