What's It?

Edit_vnc2swf is an editing tool for vnc2swf outputs. This program allows you to edit a .swf (Macromedia Flash) file generated by vnc2swf recorder. Also this program does some optimization to reduce the movie size a little bit.

NOTICE: This program assumes a .swf file generated by only vnc2swf or this program itself. The behaviour when other types of .swf files are given is not defined. Generally you cannot manipulate other files in this way.

Usage

1. To reorganize a movie:

You can splice, crop, concatinate, or attach with an mp3 file to movies. In each case, the program dumps an HTML file to embed the movie. You can preview the reorganized movie by opening that file.

  1. Resample frames:
    $ edit_vnc2swf.py -o out.swf -f 100-200,350- input.swf > out.html

    (save a new movie out.swf which consists of frames only 100 to 200, 350 to the end from the original.)

  2. Concatinate multiple movies:
    $ edit_vnc2swf.py -o out.swf input1.swf input2.swf > out.html

    (save a new movie out.swf which plays input1.swf and input2.swf sequentially)

    NOTICE: If both files include mp3 files, its sample rate and the number of channels (stereo/mono) must be the same.

  3. Crop a certain area of a movie: 
    $ edit_vnc2swf.py -o out.swf -C 100x100+10+10 input.swf > out.html

    (crop the speficied area of the original movie.)

  4. Attach an mp3 audio: 
    $ edit_vnc2swf.py -o out.swf -a voice.mp3 input.swf > out.html

    (save a new movie out.swf attached with mp3 file voice.mp3.) 

    $ edit_vnc2swf.py -o out.swf -a voice.mp3 -S 10000 input.swf > out.html

    (save a new movie out.swf attached with mp3 file voice.mp3, with the first 10,000 samples are skipped.)

    NOTICE: Without specifying anything, the original mp3 file is copied verbatim (if any). If you want to erase the mp3 file, specify an empty file (or /dev/null) when attaching mp3.

2. To extract an mp3 sound:

$ edit_vnc2swf.py -o voice.mp3 input.swf

(save the main sound stream of the movie as voice.mp3 )

3. To take a snapshot of certain frames of a movie:

$ edit_vnc2swf.py -o frame.png -f 0,1,2 input.swf

(save the screenshot of frame 0, 1 and 2 into files frame-000.png, frame-001.png and frame-002.png, respectively.)

4. To splice mp3 files:

There is an additional tool called edit_mp3.py, which allows you to extract a certain part of an mp3 audio file as follows: 

$ ./edit_mp3.py '0-100,1000-2000' a.mp3 > b.mp3

Or, to concatinate them: 

$ ./edit_mp3.py a.mp3 b.mp3 > c.mp3
NOTICE: The sample rate and the number of channels (stereo/mono) in two files must be the same.
