Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Flutter app crashes in release mode when initializing FlutterFFmpegConfig() ;
18 février 2021, par Mahmoud EidarousThe app is working on Android on Debug mode(only) with no errors in the logcat/terminal.
But when I tested it on iOS (even in debug mode), it crashes on a specific page.
After long tests, I could know that this line was causing the app to crash.


FlutterFFmpegConfig _flutterFFmpegConfig = FlutterFFmpegConfig();



If I comment that line, the app won't crash, but I need that line to manipulate videos in the app.


I'm using
flutter_ffmpeg: ^0.3.0
inpubspec.yaml
, andfull-gpl
package is set inandroid\build.gradle


ext {
 flutterFFmpegPackage = "full-gpl"
}



Related package initializations code snippet :


final FlutterFFmpegConfig _flutterFFmpegConfig = new FlutterFFmpegConfig();
final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();
final FlutterFFprobe _flutterFFprobe = new FlutterFFprobe();



I'm not sure, but it seems like the app can't handle creating all these objects at the same class !
Anyone familiar with this problem ?

Problems cropping videos with ffmpeg -ss -t
8 décembre 2016, par Alex BollbachI have been trying to figure out how to precisely crop out sub-sections of a video
final.mp4
, for example a cropped video with range [0.2, 0.28] or [9.1, 10.2]. So I’ve been using ffmpeg with -ss and -t options. The following command (or some similar form) is what I’ve seen prescribed :ffmpeg -y -i final.mp4 -ss 00:00:01 -t 00:00:01.5 -acodec copy -vcodec copy crop1.mp4
What I expect is a cropped video of length 1.5 starting at time
1.0
, but I get a broken video that doesn’t play. Or I’ll try :ffmpeg -y -i final.mp4 -ss 1 -c copy -t 1.5 crop1.mp4
and get a video with the audio cropped to 1.5 seconds but the video lasting much longer freeze framed.
The point is this should be a relatively straightforward operation but I’m running into problems at every turn. What is wrong with these commands ? My original video is a 7 minute youtube ripped mp4 which I trimmed down to 10 seconds (this seemed to work). But now further finer-grain trimming of that video is showing confusing behavior. Perhaps my video file is somehow in a bad state from the first trimming ?
