How to fix ffmpeg complex filters "Invalid stream specifier" [duplicate]
15 mai 2019, par ChaseThis 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]

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 :-
