  • Convert fla and swf to mp4 video

    4 mai 2021, par Max Williams

    I have an .fla file and a .swf file which were intended to make a Flash Video some years ago.

    


    I want to make an mp4. i tried simply passing the swf into ffmpeg, and the resulting mp4 file had the audio but no video. If I use the fla and the swf, would I get video too ? I don't know how Flash worked wrt the different file types.

    


    EDIT : as asked for, the output from doing just the swf and from using both as the input :

    


    swf alone :

    fate/subtitles : Add JACOsub remuxing test

    This muxer was untested up until now ; had it been tested, it would
    
have been obvious that it has been broken for years.

    fate/subtitles : Add remuxing test for lrc

    It uses the test-lrc.lrc sample which was added years ago, but never
    
used until now.
