  12 février 2019, par Frank Nicklin

  Im using NReco Videoconvertor on and asp.net web service but its failing with the error

  ****Error : Cannot convert media : Error opening filters !****

  When testing on my local development PC Windows 10 VS2017 it works fine. If I manually run ffmpeg as this too work fine

  ffmpeg -i c:\tempfolder\5239.hevc c:\tempfolder\5239.mp4. 

  However if I try the same from my Windows 2016 Server I get a could not find codec parameters error :-

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

  15 mai 2019, par Chase

  • ffmpeg : chain of multiple filter_complex, re-using intermediate output stream
    
    1 answer
    

  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
