• Filter complex with split source and multiple overlays : Can my code be simplified ?

  29 juin 2024, par Patrick Hennessey

  I've created a complex split filter that splits a single 1372 x 1372 input source into multiple uniquely shaped and cropped slices (s1, s2, etc), and overlays them on a padded background plate into a single output. It also applies a 20fps target framerate on the last overlay step.

  


  It works exactly how I want, but I'm wondering if this code is inefficient or redundant in any way :

  


  ffmpeg -i test.mp4 -filter_complex "[0:v]split=5[s1][s2][s3][s4][s5];
[s1]scale=377:377,crop=360:360:2:2,pad=1920:1080:1560:720[bg];
[s2]crop=1372:1068:0:0[s2];[bg][s2]overlay=0:0[bg];
[s3]crop=460:308:0:1064[s3];[bg][s3]overlay=1372:0[bg];
[s4]crop=460:308:456:1064[s4];[bg][s4]overlay=1372:308[bg];
[s5]crop=460:308:912:1064[s5];[bg][s5]overlay=1372:616,fps=20" output.mp4


  


  Is there a more elegant way to achieve the same result ?

  


• ffmpeg - split video into multiple parts with different duration

  16 avril 2023, par Pierrou

  in order to split very old episodes from my VHS rips, I would like to split video files into multiple parts according to timestamps in csv file :

  


  file1;00:01:13.280;00:14:22.800;Part 1
file1;00:14:41.120;00:26:05.400;Part 2
file1;00:26:23.680;00:39:41.720;Part 3
file1;00:40:00.000;00:51:43.280;Part 4
file1;00:53:50.200;01:06:15.680;Part 5
file1;01:06:33.960;01:20:58.400;Part 6
file1;01:21:16.680;01:34:57.320;Part 7
file1;01:35:15.600;01:48:21.640;Part 8
file1;01:49:15.160;01:51:54.720;Part 9
file2;00:01:13.280;00:13:30.960;Part 1
file2;00:13:49.240;00:29:04.240;Part 2
file2;00:29:22.520;00:43:24.080;Part 3
file2;00:43:42.360;00:58:12.560;Part 4
file2;01:00:03.880;01:12:52.840;Part 5
file2;01:13:11.120;01:24:13.280;Part 6
file2;01:24:31.560;01:51:12.720;Part 7
file2;01:52:06.840;01:54:55.640;Part 8


  


  So how can I have multiple lines like those ?

  


  ffmpeg -i file1.avi -c copy -ss 00:01:13.280 -to 00:14:22.800 file1/part1.avi


  


  So I would like to keep each parts in individual files and remove everything else.

  


• Split video stream with FFmpeg and play part with FFplay [closed]

  22 mars 2024, par Jan Hein

  I have a video stream send with FFmpeg to a other computer on my local network.
At the receiver computer I want to split the video stream in multiple parts and play them at the receiver computer. How can I do that ?

  


  Example :
Stream send form sender to receiver is 1000x1000 pixels.
At the receiver split the 1000x1000 pixel stream into four parts of 500x500 pixels, and play them all four on the receiver in a separate player.

  


  I have tryed it with a multicast stream to the receiver, and played it four times with FFplay, but that was not working correct.

  


  I also hve looked for multiple outputs with FFmpeg and then multiple pipes to FFplay, but could not find a solution.
