Trimming issue

[vasanthudhaya]

@jeromewu, Thanks for this wonderful repo.

My problem here is trimming a 5 min video to 10 sec. But the output video duration returns a wrong duration.

Kindly let know me if there any way to resolve this issue. That will be very helpful for me.

Steps to reproduce the behavior:

 const { createWorker } = FFmpeg;
 const worker = createWorker({
        corePath: '../../ffmpeg-core.js'
 });
 await worker.load();
 await worker.write('trim.mp4', videourl);
 await worker.trim('trim.mp4', 'trimed.mp4', `00:01:00`, `00:01:10`);
 const { data } = await worker.read('trimed.mp4');
var __Blobdata = new Blob([data.buffer], { type: 'video/mp4' });
var trimedurl = URL.createObjectURL(__Blobdata);

For the wrong duration, is it shifted by few seconds or can you elaborate more about that?
And it will be great if you can provide some sample data for me to test.

@jeromewu, Yes for the wrong duration it shift by few minute. Below is your testing link of codepen site and upload a video that has more than minute and run the trim function.
