  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang 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.

  • How can I display an image from Uint8List with the format AVFormat.RGBA8888 more quickly in Flutter ?

    27 mars, par Salawesh

    I'm looking to display images as quickly as possible. input data is in the form of Uint8List from dart:typed_data, data is encoded in AVFormat.RGBA8888 from ffmpeg.

    


    I'm looking for a solution to improve the performance of my graphics rendering code. And to see if it's possible to do it in a thread (isolate or compute).

    


    Here's my current working code.

    


        final buffer = await ui.ImmutableBuffer.fromUint8List(data.data);
    final descriptor = ui.ImageDescriptor.raw(
      buffer,
      width: data.width,
      height: data.height,
      pixelFormat: ui.PixelFormat.rgba8888,
    );
    final codec = await descriptor.instantiateCodec(); // native codec of ui.Image
    final frameInfo = await codec.getNextFrame();


    


    This is done in my main thread

    


  • Kivy Crashes when Loading Multiple Audio Files

    26 mars 2022, par Omid Ketabollahi

    I have a music folder and in it I have a script that loads all the files using SoundLoader and assigns them to a variable. I have 9 audio files that I load in the script but it seems like that kivy cannot handle loading many audio files ? When I run my main script I get this error and the program crashes :

    


    Assertion 'pa_atomic_load(&(c)->_ref) >= 1' failed at pulse/context.c:1056, function pa_context_disconnect(). Aborting.


    


    I don't think that this is an issue with the audio files ( I may be wrong ) because I tried loading other files instead of the original ones that I used and I still got this error.

    


    In case you are wondering, this is the code :

    


    import os.path
from typing import Final
from constants import MUSIC_DIRECTORY
from kivy.core.audio import SoundLoader

__all__ = (
    "A_DARK_TIME",
    "BLOOD_PUMPING",
    "BROKEN_VILLAGE",
    "DRUM_COMMERCIAL_B",
    "SUPER_SUSPENSE",
    "THE_HERO_WE_NEED",
    "TROUBLE_IS_BREWING",
    "VIKING_FEAST",
    "WARRIOR_GODS",
)


A_DARK_TIME: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "A-Dark-Time-David-Fesliyan.mp3")
)
BLOOD_PUMPING: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Blood-Pumping-David-Fesliyan.mp3")
)
BROKEN_VILLAGE: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Broken-Village-David_Fesliyan.mp3")
)
DRUM_COMMERCIAL_B: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Drum-Commercial-B-David-Fesliyan.mp3")
)
SUPER_SUSPENSE: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Super-Suspense-David-Fesliyan.mp3")
)
THE_HERO_WE_NEED: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "The-Hero-We-Need-Steve-Oxen.mp3")
)
TROUBLE_IS_BREWING: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Trouble-Is-Brewing-David-Fesliyan.mp3")
)
VIKING_FEAST: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Viking-Feast-David-Fesliyan.mp3")
)
WARRIOR_GODS: Final = SoundLoader.load(
    os.path.join(MUSIC_DIRECTORY, "Warrior-Gods-Steve-Oxen.mp3")

  • File Decryption in (AESMode.ctr) mode showing Exception Failed to decode data using encoding 'utf-8' in dart ?

    20 novembre 2020, par Jai

    While decoding the video file using aes-ctr mode am getting error like below,

    


    Unhandled Exception: FileSystemException: Failed to decode data using encoding 'utf-8'

    


    Used ffmpeg for encrypting file :

    


    ffmpeg -i samplevideo.mp4 -vcodec copy -acodec copy -encryption_scheme cenc-aes-ctr -encryption_key 76a6c65c5ea762046bd749a2e632ccbb -encryption_kid a7e61c373e219033c21091fa607bf3b8 enc_v1_file.mp4

    


    Used Dart to decode video file :

    


    Future<string> decryptFile(filePath) async {&#xA;    // filePath - Local encrypted file path&#xA;    var encodedKey = &#x27;NzZhNmM2NWM1ZWE3NjIwNDZiZDc0OWEyZTYzMmNjYmI=&#x27;;&#xA;    var encodedIv = &#x27;YTdlNjFjMzczZTIxOTAzM2MyMTA5MWZhNjA3YmYzYjg=&#x27;;&#xA;    var encryptedBase64EncodedString = new File(filePath).readAsStringSync();&#xA;    var decoded = base64.decode(encryptedBase64EncodedString); // Error in this line&#xA;    final key1 = enc.Key.fromBase64(encodedKey);&#xA;    final iv = enc.IV.fromBase64(encodedIv);&#xA;    final encrypter = enc.Encrypter(enc.AES(key1, mode: enc.AESMode.ctr));&#xA;    final decrypted = encrypter.decryptBytes(enc.Encrypted(decoded), iv: iv);&#xA;    final filename = &#x27;${p.basenameWithoutExtension(filePath)}.mp4&#x27;;&#xA;    final directoryName = p.dirname(filePath);&#xA;    final newFilePath = p.join(directoryName, filename);&#xA;    var newFile = new File(newFilePath);&#xA;    await newFile.writeAsBytes(decrypted);&#xA;    return newFilePath;&#xA;}&#xA;</string>
