Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

ffmpeg : trim / concat results in different length videos
4 mai 2019, par Mads Lee JensenIm experimenting with the
trimandconcatfilters.I wanted to simply split up a video into X chunks, and
concatit again. I expected the result would be a video with same frames / duration.So i have a video encoded with 1 fps and contains 3 frames, the duration of this video is 3 seconds.
i run the following script
ffmpeg -y -i fps.mp4 -an -filter_complex "[0:v]trim=0:1[v1];[0:v]trim=1:2[v2];[0:v]trim=2:3[v3];[v1][v2][v3] concat=n=3:v=1 [out]" -map [out] out.mp4The result is a video with a duration of 4 seconds to inspect the problem i called :
ffprobe -print_format json -show_frames out.mp4It shows that there is now 4 frames ?? (here is the dump)

}I tried different things, and everything seems to work fine if i split a 2 second video (still 1 fps) up and concat again. But something goes wrong when going beyond that ?

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.mp4If 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];
