  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • ffmpeg timelapse discard garbage jpg [duplicate]

    12 mai 2021, par piekn

    I'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 Vasudev

    This is the current code to generate thumbnails for Video and Audio files.. It is working fine in most cases.

    


    @override&#xA;Future<imageprovider> thumbnail(String path,&#xA;{required double width, required double height}) async {&#xA;&#xA;&#xA;  final FFmpegSession session = await FFmpegKit.executeAsync(&#xA;          "-loglevel quiet -i &#x27;$filePath&#x27; -y -ss 00:00:00.000 -vframes 1 &#x27;$thumbnailPath&#x27;");&#xA;&#xA;&#xA;  final returnCode = await session.getReturnCode();&#xA;  if (returnCode == null || returnCode.isValueError()) {&#xA;    throw Exception("Thumbnail generation failed");&#xA;  }&#xA;&#xA;/* Returns ImageProvider */&#xA;}&#xA;</imageprovider>

    &#xA;

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

    &#xA;

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

    &#xA;

      final FFmpegSession session = await Isolate.run(&#xA;    () async {&#xA;      return await FFmpegKit.executeAsync(&#xA;          "-loglevel quiet -i &#x27;$filePath&#x27; -y -ss 00:00:00.000 -vframes 1 &#x27;$thumbnailPath&#x27;");&#xA;    },&#xA;  );&#xA;

  • Android - 360 video metadata

    11 mai 2017, par Xys

    So 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 copy

    I 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 !
