  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • How to fix ffmpeg complex filters "Invalid stream specifier" [duplicate]

    15 mai 2019, par Chase

    This question already has an answer here :

    I’m attempting to scale and blur (sections of) a video with ffmpeg complex filters. This has actually been working in production for years.

    I’m now running a newer build of ffmpeg on Ubuntu 18.04 and getting an error relating to the filters where the same command works fine on Ubuntu 16.04’s ffmpeg against the same video.


    Specifically, I’m seeing the following error :

    mov,mp4,m4a,3gp,3g2,mj2 @ 0x56055a5902c0] Invalid stream specifier: vs0.
    
    Last message repeated 1 times
    
Stream specifier 'vs0' in filtergraph description ... matches no streams.

    Has something about the complex filter API changed that would make this same input invalid in a newer version of ffmpeg ?

    The command in question is just running the following in a Bash terminal.

    ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

    If we break up the complex filter statement, it looks like :

    [0:v]scale=-2:'min(320,ih)'[vs0];
    
[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];
    
[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];
    
[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];
    
[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];
    
[ovr1][b2]overlay=main_w/9:0[vs1]

    On ffmpeg version N-86980-g62b7553 (Ubuntu 16.04), everything works great as it has done for years.

    $ ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4
