  I am coming from this question
  https://askubuntu.com/questions/610903/how-can-i-create-a-video-file-from-a-set-of-jpg-images

  Everything is working fine and I can create a video, I am only struggling with the image name pattern. Each time, I had to rename all files first to a specific pattern.

  Can we create a video using the same command written below but with this kind of image name pattern ?

  2018-01-19-11-55-00.jpg  2018-01-19-17-00-00.jpg  2018-01-22-10-10-00.jpg  2018-01-22-13-25-00.jpg  2018-01-22-16-40-00.jpg

  I want to use this command

  ffmpeg -framerate 25 -i image-%04d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4

  but this one using

  image-2000.jpg  image-2400.jpg  image-2800.jpg

  above image pattern.

  Is there any possibility to use the above pattern of files which are being named as a date. also, all these images are in a folder. Can FFMPEG address them ?

• Concat different video file types with different fps and resolutions using FFmpeg

  10 juillet 2018, par 1234567

  This is the command I am using :

  {"-y", "-i", file1.toString(), "-i", file2.toString(), "-strict", "experimental", "-filter_complex",
  
                  "[0:v]scale=480x640,setsar=1:1[v0];[1:v]scale=480x640,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1",
  
                  "-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", rootPath + "/output.mp4"};

  When file types are similar, in my case mp4, and with same fps 30 and same resolution, 720 x 980, they do merge properly. But when I try different file types, say AVI, 3gp, mp4, then all with different fps and resolution and the AVI file with no audio, I get following error :

  What is the proper command to concat different file types, with different fps, and different resolution and map audio properly to a set fps and resolution, output being mp4 file ?
