  • Error trying to install FFmpeg on Oracle Cloud VM Linux [closed]

    14 mai 2022, par lucasrvimieiro

    I'm trying to host a discord bot using Oracle Cloud but I need to install the FFmpeg extension for it to be able to play music. I have absolutely no experience with Linux at all but I was able to run the bot normally after a few tutorials. Everything is working fine except for the FFmpeg installation.

    


    I already tried following these guides :
https://computingforgeeks.com/how-to-install-ffmpeg-on-centos-rhel-8/
https://techviewleo.com/install-ffmpeg-on-rocky-almalinux-oracle-linux/

    


    However I keep getting the error :

    


    


    Errors during downloading metadata for repository 'nux-dextop' :

    


    


    


    when executing :

    


    sudo dnf -y install ffmpeg


    


    I cannot find any solutions online. Is it even possible to install FFmpeg there ? The VM is running Oracle-Linux-8.5-aarch64-2022.04.04-0. I'm using Bitvise SSH Client to connect to the terminal.

    


  • Reducing FFmpeg dlls to only what is used ?

    1er juin 2021, par XylemFlow

    I have written Windows software that calls the FFmpeg dlls to encode a sequence of images in a few different formats (animated gif, animated png, mpeg4, wmv, webm). I need to provide the dlls with my software but they significantly increase the download size. Even after zipping everything they increase the size from around 5MB to around 20MB. This isn't a huge problem but I'd like to get the download size down as much as possible.

    


    How easy is it to do this and by roughly how much would I be able to reduce them ? Note that I don't need any decoders and am only encoding those 5 formats. I'm not using any special filters and the encoded videos don't have sound. I'd like to know if it's worth it before I start trying to compile the FFmpeg source and playing with configuration flags.
