This information could be omitted.

But it becomes quite important for correctness of GPS Data stored in Stream #2.

Unfortunately, all the settings I have tried for FFMPEG, do not preserve the duration of Stream #2.
& the output ends up looking like this :

Generate Multiple Thumbnails from Multiple Videos (with FFmpeg)
30 juin 2020, par netsonicyxfI have multiple videos in different locations, something like :
D :\Folder 1\001.ts
E :\Folder 2\abc.avi
F :\Foder X\视频.mp4 (some videos name are in non-English languages)


And I already have a filelist.txt with these file path in it




file 'D :\Folder 1\001.ts'






file 'E :\Folder 2\abc.avi'






file 'F :\Foder X\视频.mp4'




For each video, I want to generate 3 images, starting from 00:00:10, then next image every 10 sec.
The name of the image should be the name of the video + number staring from 1, something like
001_1.jpg, 001_2.jpg, 001_3.jpg
abc_1.jpg, abc_2.jpg, abc_3.jpg
视频_1.jpg, 视频_2.jpg, 视频_3.jpg


how to do it in Windows 10 ?
