• 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")
)


  


• split/select/overlay Buffer queue overflow, dropping

  18 août 2015, par basin

  This command is a simplified version of the real command. It’s supposed to write 4 seconds of first input into out0.mkv and overlay the same first input on top of second input and write the result into out1.mkv

  ffmpeg -y \
  
      -f lavfi -i testsrc=s=640x480:d=10:r=25 \
  
      -f lavfi -i testsrc=s=640x480:d=10:r=25 \
  
      -filter_complex "
  
          [0:v]split=2[in0-0][in0-1];
  
          [in0-0]select='lt(t,4)'[out0];
  
          [1:v][in0-1]overlay[out1]
  
          " \
  
      -map '[out0]' out0.mkv \
  
      -map '[out1]' out1.mkv

  During processing it prints Buffer queue overflow and in the end there’s a still image in out1.mkv.

  My guess is that one of the nodes in filter graph cannot consume new frames from one input, because it’s waiting for another input, but I don’t understand why.

  It looks like out1 is waiting for out0, although they should be independent
