  • SharedArrayBuffer not defined when using Cypress

    15 janvier 2023, par unloco

    I'm using Vite and Cypress for dev and testing

    


    I'm loading ffmpeg, it loads fine on Chrome but on Cypress, it gives this error

    


    ReferenceError: SharedArrayBuffer is not defined


    


    Apparently, it's caused by cross origin isolation.

    


    I tried disabling web security in Cypress.json but it didn't help

    


    Sample code

    


    import { createFFmpeg } from "@ffmpeg/ffmpeg"

const ffmpeg = createFFmpeg({ log: true })
ffmpeg.load()



    


    Is there a workaround ?

  • Reducing latency of FFmpeg audio stream using Opus encoding

    28 septembre 2022, par Victor Almeida

    I'm trying to stream my microphone audio using FFmpeg, but there's a delay of about 3 seconds from when the audio is recorded to when it is played.

    


    The snippet below contains the minimal command for which I can reproduce the problem.

    


    ffmpeg -f dshow -i "audio=Microphone (Realtek(R) Audio)" -f opus - | ffplay -


    


    However, I've tried various other flags to no effect. Such as :

    


      

    • -analyzeduration 0

      • 


    • -loglevel 0

      • 


    • -audio_buffer_size 50

      • 


    • -fflags nobuffer

      • 


    • -flags low_delay

      • 


    • -acodec libopus

      • 


    


    Is there any way to reduce the latency to less than a second while still using Opus encoding ?
