• Why is my discord.py bot not having voice while being hosted on Heroku ?

  24 juillet 2020, par Flying Thunder

  My bot is all set up and running, everything works, EXCEPT for voice : He joins the channel, but doesnt play audio. I have heard many different claims for what the reason is (no permission to use ffmpeg.exe, missing buildpack, missing dependency, Heroku blocking UDP on free users...) - but i hope that someone here ACTUALLY knows what the problem is, because i couldnt find any definitive reason online.

  


  This is the code of the bot : https://github.com/FlyingThunder/DiscordBot/blob/master/main.py
Everything is working fine on my machine.
This is the only error that Heroku logs gave me :
2020-07-24T06:28:30.329937+00:00 app[worker.1]: PermissionError: [Errno 13] Permission denied: 'res/ffmpeg.exe'

  


  I already tried adding https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git to my buildpacks, and i added cffi==1.14.0 to my requirements.txt - both solutions that are supposed to fix this exact issue.

• ffmpeg : Extract unknown data stream from video container

  23 juillet 2020, par Pikkostack

  I have a .MOV container which contains the following tracks :

  


  Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 100619 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)
Metadata:
  creation_time   : 2020-07-21T22:48:24.000000Z
  handler_name    : DJI.AVC
  encoder         : AVC encoder
Stream #0:1(eng): Data: none (priv / 0x76697270), 87 kb/s
Metadata:
  creation_time   : 2020-07-21T22:48:24.000000Z
  handler_name    : DJI.Meta
Stream #0:2(eng): Subtitle: mov_text (text / 0x74786574), 2 kb/s (default)
Metadata:
  creation_time   : 2020-07-21T22:48:24.000000Z
  handler_name    : DJI.Subtitle


  


  As you can see, stream #0:1, called DJI.meta, is of an unknown data format. I just want to extract the raw data of this stream to a file. So that is the ffmpeg command I tried :

  


  ffmpeg -i .\DJI_0001.MOV -map 0:1 metadata


  


  But using this command results in the following error :

  


  Unable to find a suitable output format for 'metadata'
metadata: Invalid argument


  


  How can I tell ffmpeg that the data should not be formated, so that only the raw data is extracted ?
