Flutter | Retrieve ffprobe data
23 juin 2021, par YourLogarithmI'm using
flutter_ffmpegpackage, specifically I'm trying to retrieve information regarding the chapter marks from a.m4bfile which is an audiobook. By using this method :

_flutterFFmpeg.executeWithArguments(['-i', widget.book.path, '-print_format', 'json', '-show_chapters', '-loglevel', 'error']);


I was able to output this data as a JSON map in the console. The thing is, I need to use this data inside my application, is there a way to get access to those chapters as a variable using another approach, or maybe to access this data directly from the console log printed by the method shown earlier.

Adding cover art to video wtih chapters and chapters getting deleted
31 mai 2021, par throwaway513I am trying to add a cover art to a video with chapters.


I added 2 chapters to a video using :


ffmpeg -i 1.mp4 -i Chapters.txt -map_metadata 1 -c copy 2.mp4

but when I try to add cover art it deletes the first chapter and only keeps the second ?


ffmpeg -i 2.mp4 -i image.jpg -map 1 -map 0 -c copy -disposition:0 attached_pic 3.mp4

I also tried mp3tag but the picture doesn't show on the file after adding chapters through ffmpeg. Chapters work fine on 2.mp4 but on 3.mp4 it deletes the first chapter. It also deletes the chapter when I do
ffmpeg -i 2.mp4 -c copy any.mp4
