Trim the video to 5 minutes

Question

I am working on a demo project on which I have to get only 5 minutes video is there any way to trim the video to 5 minutes only. Currently, I am using FFmpeg flutter to get the video file and its metadata.

Solution 1

You can use following command code to split a video.

final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();   

_flutterFFmpeg
  .execute(
    '-i videoplayback.mp4 -ss 00:00:50 -t 00:01:30 -c copy smallfile1.mp4')
  .then((value) {
    print('Got value ');
  }).catchError((error) {
    print('Error');
  });

Start time is -ss 00:00:50 end time is 00:01:30

Solution 2

You can use any ffmpeg command in execute() method of flutter-ffmpeg package, to trim first 5 minutes of video

import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';
....

final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();
_flutterFFmpeg.execute("-ss 00:00:00 -i input.mp4 -to 00:05:00 -c copy output.mp4").then((rc) => print("FFmpeg process exited with rc $rc"));

Solution 3

For getting video information you may can try following code.

fFmpeg.execute('-i video.mp4 -f null /dev/null').then((value) {
  print('Got value ');
}).catchError((error) {
  print('Error');
});

FFmpeg is taking too long for getting metadata of video like 25seconds for 6 minutes video is there any way to cut short this time.

I have got a path to the video. I want to fetch metadata with the absolute path of the video.

Only video name is given in ffmpeg arguments in your code.

When i trim with ffmpeg, the first few seconds, i get only the sound no video. After few seconds is when the video comes. What could be the issue.
