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 ?

Flutter : Running FFmpeg.execute to generate thumbnails in a different isolate doesn't work ?
12 novembre 2024, par VasudevThis is the current code to generate thumbnails for Video and Audio files.. It is working fine in most cases.


@override
Future<imageprovider> thumbnail(String path,
{required double width, required double height}) async {


 final FFmpegSession session = await FFmpegKit.executeAsync(
 "-loglevel quiet -i '$filePath' -y -ss 00:00:00.000 -vframes 1 '$thumbnailPath'");


 final returnCode = await session.getReturnCode();
 if (returnCode == null || returnCode.isValueError()) {
 throw Exception("Thumbnail generation failed");
 }

/* Returns ImageProvider */
}
</imageprovider>

Now in iOS, for large files, the thumbnail generation doesn't really fail. But takes a long time and doesn't complete at all.


This causes performance issues. I would like to run this FFmpeg.execute() in a different isolate, but it doesn't work at all.


final FFmpegSession session = await Isolate.run(
 () async {
 return await FFmpegKit.executeAsync(
 "-loglevel quiet -i '$filePath' -y -ss 00:00:00.000 -vframes 1 '$thumbnailPath'");
 },
 );

Android - 360 video metadata
11 mai 2017, par XysSo with ffmpeg I’ve concatenated two 360 videos into one. The problem is that I lost all the 360 video metadata in the final video (so it’s not recognized as a 360 video anymore). If I use exiftool on the final video, I lack those metadatas :
- Spherical : true
- Stitched : true
- Stitching Software : Spherical Metadata Tool
- Projection Type : equirectangular
I’ve tried to inject those metadatas with ffmpeg, like this for example :
ffmpeg -i -metadata Spherical="true" -codec copyI don’t get any errors doing that, but exiftool still doesn’t show the metadatas.
I know Google has a Python script that does this well, here .
But I would like to inject metadatas in my app as well, any help would be much appreciated,
thanks !
