Hi . I am trying to use the plugin but it doesn't work . Here is my code :
` String bytes;

@OverRide
void initState() {
super.initState();
getThumb();
}

void getThumb() async {
final Directory _dir = await getTemporaryDirectory();
bytes = await VideoThumbnail.thumbnailFile(
video:
'/storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20200405-WA0024.mp4', //'https://youtu.be/jnzOMiMsmdI',
thumbnailPath: _dir.path,
imageFormat: ImageFormat.PNG,
);
}

@OverRide
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {},
child: Card(
elevation: 2.2,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(16),
),
child: ClipRRect(
borderRadius: BorderRadius.circular(16),
child: Image.memory(
File(bytes).readAsBytesSync(),
fit: BoxFit.cover,
),
),
),
);
}And here is the error : Exception: Could not instantiate image codec.

I am also not able to generate a video thumbnail here is my code,

final thumnbnailString = await VideoThumbnail.thumbnailFile(
video: file.path,
imageFormat: ImageFormat.JPEG,
maxWidth:
128, // specify the width of the thumbnail, let the height auto-scaled to keep the source aspect ratio
quality: 25,
);

Looks like you guys need to check the permissions for reading and writing on storage.
Also please take a look my example.

@Loopex2019 Try to give an integer value for the 'maxWidth'.

@ThalapathySiva Looks like the thumbnail file was treated as a network resource. Try to remove or add the prefix 'file://' for the returned thumbnail file path, or just create the thumbnail as binary data, then save it to file as what I demonstrated in the example.

Nope it didn't work . Here is my code :
void getThumb() async { var status = await Permission.storage.request(); if (status.isGranted) { final Directory _dir = await getTemporaryDirectory(); bytes = await VideoThumbnail.thumbnailFile( video: widget.videoUrl, thumbnailPath: _dir.path, maxWidth: 200, maxHeight: 200, imageFormat: ImageFormat.PNG, ); } else { openAppSettings(); } }

Try to generate the thumbnail in memory to see any different.

I solved this Problem. Sorry the problem was not in the plugin. It was caused by another plugin which I forgot to dispose its object . But thanks for help!!
