How can I display an image from Uint8List with the format AVFormat.RGBA8888 more quickly in Flutter ?
27 mars, par SalaweshI'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 KetabollahiI have a music folder and in it I have a script that loads all the files using
SoundLoaderand 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")

20 novembre 2020, par JaiWhile decoding the video file using
aes-ctrmode am getting error like below,

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

Used ffmpeg for encrypting file :
