• ffmpeg crashes in electron mac apple store build

  23 février 2021, par Martin

  UPDATE
I found the command otool -L ffmpeg-mac/ffmpeg | grep /usr/local which shows me which dynamicly linked files are in my ffmpeg build, it was point to 3 files so I moved them to my desktop and then built my mac apple store build, uploaded it to the app store, downloaded it, and tried to run it again but got a new less-descriptive error :

  The error says command failed with exit code 1 Operation not permitted, am I missing some entitlements for saving files on my computer in the final mac apple store build that gets uploaded to the app store ?

  I am trying to release an electron app on the Mac Apple Store (mas), my electron app uses ffmpeg to render videos. In order to release my app on the mac apple store, It needs to be sandboxed, and by default ffmpeg makes calls to external libraries so I need to statically build ffmpeg and package it with my app. I have successfully built my app, submitted it to the app store, had it approved, and downloaded/used it but my ffmpeg fails with this errir :

  I think this line is important ; file system sandbox blocked open() of '/usr/local/opt/libass/lib/libass.9.dylib' but I'm not sure what I should change with my static ffmpeg build so that it works in production and so that I can avoid the above error.

  


  My code is available on the branch mas-attempt-after-redesign here : https://github.com/MartinBarker/digify/tree/mas-attempt-after-redesign

  


  Inside my package.json I have the command download-ffmpeg which clones the ffmpeg repo, runs a configure command with some flags, and then builds ffmpeg into a folder called 'ffmpeg-mac', this folder gets packaged with the app for the mac apple store build.

  


  git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg-mac && cd ffmpeg-mac && ./configure pkg_config='pkg-config --static' --pkg-config-flags='--static' --libdir=/usr/local/lib --extra-version=ntd_20150128 --disable-shared --disable-lzma --enable-gpl --enable-pthreads --enable-nonfree --enable-libass --enable-libfdk-aac  --enable-libmp3lame  --enable-libx264 --enable-static --enable-filters --enable-runtime-cpudetect && make && cd ..


  


  You can see in the above ffmpeg command the flag --enable-libass, but even though I have that flag included, after I build and sign my mac apple store build by running sudo rm -rf dist/mas/ && npm run build-mas && sh mas-sign-script.sh, the production build (once approved) fails with the above included error.

  


• How do I make my discord.py bot play a sound effect ?

  15 mai 2024, par Kronik71

  My bot is supposed to be some sort of jeopardy quiz show type of bot. /joinvc makes the bot connect to the call, however, I cant seem to make the bot make noise when its in a vc. Here's some of the code :

  


  @interactions.slash_command(
    name="press",
    description="Press the button"
)

async def press(ctx: interactions.ComponentContext):
    await ctx.send(f"{ctx.author.mention} has pressed the button")
    vc = ctx.author.voice.channel
    player = vc.create_ffmpeg_player('audiopath', after=lambda: print('done'))
    player.start()


  


  But whenever I use the /press command, I get this error AttributeError: 'GuildVoice' object has no attribute 'create_ffmpeg_player'

  


  Is it something I did wrong with ffmpeg ?

  


  I tried using a different way to write the code, basically grabbing the ffmpeg.exe path and the audio path, didn't work either. I just want the bot to play a small noise whenever someone uses /press command.

  playing the playsound slash command but wasn't expecting it to not play the mp3 file.

  


  everything else worked fine except when it transmits the sound it doesn't play it.
