4 years ago Your command fails due to a syntax error. Can you try the following one?
var arguments = [
"-y",
"-i",
"${widget.paths[0]}",
"-vframes",
"1",
"-an",
"-ss",
"00:01:00",
"$thumbnailPath"
];

4 years ago Thanks @tanersener, but it is still failing with the same error.

flutter: FFmpeg process exited with rc 1What is ${widget.paths[0]} and $thumbnailPath in that test?
Also, did you repeat the same test on a simulator and check whether that file really exists or not?

4 years ago ${widget.paths[0]} is the path that ffmpeg cannot resolve. It is the path to a video that was recorded with the camera package. $thumbnailPath is the same path as ${widget.paths[0]} but with a different file name.
To answer your question, I know the file exists because I save it to google cloud storage with the following code and it works just fine:
final StorageUploadTask uploadTask = storageReferences[i].putFile(
File(widget.paths[i]),
StorageMetadata(
contentType: 'videos/.mp4',
),
);Also here is the code to generate ${widget.paths[0]}:
final Directory extDir = await getApplicationDocumentsDirectory();
final String dirPath = '${extDir.path}/${uid.uid.toString()}/user-posts';
await Directory(dirPath).create(recursive: true);
final String filePath = '$dirPath/${timestamp()}.mp4';Code to generate $thumbnailPath:
// widget.directoryPath is equal to dirPath in the above code
String timestamp() => DateTime.now().millisecondsSinceEpoch.toString();
thumbnailPath = '${widget.directoryPath}/${timestamp()}_thumb.png';
thumbnailReference = FirebaseStorage.instance.ref().child(thumbnailPath);My previous logs have been from an iPhone 8. I just ran the same test on an android emulator, and I got the same result:

import 'dart:io';
File file = new File(widget.paths[i]);
var statSync = file.statSync();
print("File: ${videoPath}, exists: ${file.existsSync()}, size: ${statSync.size}, mode: ${statSync.modeString()}, type: ${statSync.type}, lastModified: ${statSync.modified}");I can't reproduce this issue locally. I'm using the same functions to generate file paths and they all work fine. However, the way I use to generate the input video is different. So, can you give me some details about how can I create and access the input video as you do in your app?

4 years ago Here are the logs you requested:
flutter: File: /var/mobile/Containers/Data/Application/1DED5AF4-CE1A-21-B21B-32/Documents/1234/user-posts/1593351895519.mp4,
exists: false,
size: -1,
mode: ---------,
type: notFound,
lastModified: 1970-01-01 00:00:00.000ZI understand the above logs indicate that there is no file, but if that were the case, why does it save properly to firebase using the same File() widget?
To generally reproduce my code, you need the camera package and should do something like the following:
// you will probably need to do more initialization for the camera controller.
// I did not show it here to be more succinct
CameraController _controller = CameraController();
final Directory extDir = await getApplicationDocumentsDirectory();
final String dirPath = '${extDir.path}/${uid.uid.toString()}/user-posts';
await Directory(dirPath).create(recursive: true);
final String filePath = '$dirPath/${timestamp()}.mp4';
print("path to recording: " + filePath);
await _controller.startVideoRecording(filePath);
Timer(Duration(seconds: 3), () {
print("Waiting three seconds to record something...");
});
await _controller.stopVideoRecording();Thanks. I don't know why your upload doesn't fail. You must have been doing something differently.
Btw, tested camera and flutter_ffmpeg plugins together by modifying the test application of camera. It worked fine without any errors. You can see its source code in this gist, camera_flutter_ffmpeg.dart. When video recording is stopped flutter_ffmpeg executes a video copy command using flutter_ffmpeg.
Source code of that test is very similar to your source code. I believe you can find what is is wrong with your app by comparing its source code with this gist.

4 years ago Thanks for the gist. I figured out my issue. For some reason, I forgot that I deleted the file's sync before I generated the thumbnail. That's the reason why there was a "No such file or directory" error. 🤦🏻♂️ Thank's for all your help.
Description I am new to ffmpeg, and I am trying to allow a user to film a video and save it to their profile. However,before they save it to their profile, I am attempting to generate a png thumbnail from the previously filmed video using flutter-ffmpeg.
That being said, when I attempt to generate the thumbnail I run:
but the ffmpeg command fails with exit code 1.
Per the logs below, it is clear that ffmpeg cannot recognize the file path; however, I create the path using
path_provideras follows:The strange thing about this is that I can play the videos using said path with the
video_playerpackage; however, there appears to be something wrong with reading the videos via theflutter-ffmpegpackage. There might be some step I'm missing.Logs
