  • Mix more then 1000 mp3's sounds bad / Can I use FFmpeg to merge 1000 mp3s ?

    7 avril 2022, par maesbn

    I am working on a project where everybody has to activate a part of a song. I have about 7000 mp3's, each with the same length of the final mix but with only a small part of audio. So for example you can hear a drum hit at the 15th second and the rest of the mp3 (about 4 min.) is silence.

    



    I use the mix filter to add all the mp3's. I add them 32 mp3s at a time. 
The first test I've run results in the first mixed mp3s to be silenced ? (I set the Volume on the mix to the number of tracks) Also the sound is of poor quality after the mix. Can I fix this ?

    



    Or do you think this can not be done by ffmpeg ? Do you know an alternative program to do this ?

    



    Thanks !
B.

    


  • SWF to PNG.. but merge all pngs inside into 1

    14 novembre 2014, par Jayden

    The title says it all,

    I’ve tried swftools and ffmepg but I don’t ’think’ they achieve what I need to do.

    Basically there is a SWF file that is made up of up to 60 images, them 60 images inside the SWF all are parts of an image that make up 1 final image or animation on an online game.

    I need to be able to download the swf as a png image with the same output it will look like on the virtual game - so not 60 images if seperate graphics, just one image with them all (merged ?) together.

    I am not even sure if this is possible to do in the commandline so if you understand any of this, please point me in the right direction.

    I am using Ubuntu 14.04
