ffmpeg timelapse discard garbage jpg [duplicate]
12 mai 2021, par pieknI'm successfully creating timelapse video (jpg->mp4) using command line
$ffmpeg -r $fps -f concat -safe 0 -i $concat_file -c:v libx264 -vf 'format=yuv420p' $thumbnail 2>&1 &


But some of source jpg are 'garbage' (look picture below what I mean) - part of the picture is lost.
part of picture is lost


As result, final clip contains damaged frames (see below)
final clip


As I see, the best for me is to discard these jpg. But I have no ideas how to define them ? - file system don't see them as 'broken', etc.


Any ideas ?

ffmpeg with Flutter - Error in my code - Video not created
30 juillet 2020, par csslerI try to create a video from images with flutter and
ffmpeg. I think the logic of my code is correct, but I always get the return value1which says that the execute was not successfull.

Do you find the error in my code ?


Future<void> _onCreateVideoFromImages() async {
 Directory tempDir = await getTemporaryDirectory();
 String tempPath = tempDir.path;

 final allPictures = await picturesData.getPicturesFromAlbum(albumID);

 List textFileMap = [];

 for (var i = 0; i < allPictures.length; i++) {
 var file = File(allPictures[i].path);

 final newFile = await file
 .copySync("$tempPath/img${i.toString().padLeft(4, '0')}.jpg");

 print("File has been moved successfully to temporary folder: $newFile");

 textFileMap.add("file '" + newFile.path + "'");
 }

 print("Final list:");
 print(textFileMap);

 print("Create txt file for ffmpeg");
 final File file = File('${tempPath}/images.txt');
 final textFile = await file.writeAsString(textFileMap.join("\n"));
 print("txt file created successfully: $textFile");

 await _flutterFFmpeg.execute(
 "ffmpeg -f concat -safe 0 -i $textFile -c copy $tempPath/output.mp4")
 .then((rc) {
 if (rc == 0) {
 print("Video completed");
 } else {
 print(rc); // Returns 1
 }
 });
 }
</void>

And here the console log


flutter: File has been moved successfully to temporary folder: File: '/var/mobile/Containers/Data/Application/C28A04D5-76DF-450B-8F63-75CD39BC927F/Library/Caches/img0001.jpg'

I appreciate your help !

Join videos command line debian [on hold]
2 avril 2014, par RomanGood evening
I'm looking for a solution for the following problem :
I have to join multiple video files (webM-format) with different settings (resolution, fps, ...) into one final file. I should also add an additional audio-track who's exactly as long as all video files together (wav-format).I've tried it with ffmpeg and concat like this :
ffmpeg -i "concat:file1.webm|file2.webm|file3.webm" -vcodec libvpx -s 1280x720 -i track.wav -acodec libfaac -ab 128k -async 10 final.webmResult : Worked fine, but just with the first video file. All the others were ignored by ffmpeg.
Have you any other solution for this problem ?
Best Regards,
Roman Ackermann
