  • libswresample/swresamplec : Err num(negative-size) was used as a function parameter

    8 décembre 2021, par Yu Yang
    libswresample/swresamplec : Err num(negative-size) was used as a function parameter

    If memory allocation fails, ERROR(ENOMEM) '-12' will be returned.
    
When resample() is done first, the negative size param would cause buffer-overflow and SEGV in swri_rematrix().
    
When swri_rematrix() is run first, resample() would not cause an error but Err num as a wrong parameter passing.
    
Err num should be returned immediately. And remove an unneeded term from an assert.

  • ffmpeg -vcopy to folder without filename

    9 novembre 2017, par Musikdoktor

    I’m trying to find a command line to copy part of videos and export them to a different folder.

    The problem i need to solve is each file may have different extensions, .mxf, .dv, .avi etc some came from a internal url server that gives download links like /server/download ?id=1000 and that will download an mp4, or a mxf so i have no idea the extension.. the name is not important..

    i want to know if it’s possible or there’s an existing command line where the -y file.extension is not needed.

    For example

    ffmpeg.exe -i "/server/download ?id=1000" -vcodec copy -acodec copy -y "folder/"

    An i get a filename.avi or filename.mxf inside that "folder/"

  • Downloading a video with full capacity of my PC with FFMPEG [closed]

    25 juin 2020, par akamai

    I'm trying to download a M3U8 video with FFmpeg.
    &#xA;ffmpeg -i "www.example.com/video.mp4" -c copy -bsf:a aac_adtstoasc output.mp4

    &#xA;

    FFmpeg downloads very slowly compared to a direct download. I'm on a 1 Gigabit network and it take around 1 hour to download the entire video.

    &#xA;

    I read the documentation and they mentioned about CPU Flag&#xA;But I don't know if that will solve my problem.
