• Discord Music Bot interrupts music playback on Heroku

  29 mars 2023, par denisnumb

  I have a music discord bot written in Python. Bot plays music from YouTube using the yt-dlp library and ffmpeg.

  


  Everything worked fine, but a couple of days ago the bot began to interrupt the playback of any tracks for ~80% duration, crashing with an error :

  


  [tls @ 0x6e3b440] Error in the pull function.
[tls @ 0x6e3b440] IO error: Connection reset by peer
[https @ 0x6e37900] Will reconnect at 720896 in 0 second(s), error=Connection reset by peer.


  


  I have the latest version of py-cord=2.4.1 and yt-dlp==2023.3.4 installed. When the bot is launched on my computer, the bot plays all the tracks to the end, so the problem is clearly not in the code and not in the libraries.

  


  I suspect something is wrong with ffmpeg, so I tried installing different buildpacks, but that didn't solve the problem.

  


  At the moment I have the following installed :

  


  https://github.com/xrisk/heroku-opus.git
https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git


  


  What could be the problem and how to solve it ? Why did this problem appear only on hosting ? Why didn't this happen before ?

  


• webM files shows green and purple effects on mobile

  11 octobre 2015, par Naveen Gamage

  I have converted several GIFs to webM files using ffmpeg on my Ubuntu 14.04 server.

  Heres the code I used for conversation.

  ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

  source https://gist.github.com/ndarville/10010916

  The problem is converted webM files shows perfectly fine on PCs but on my mobile it shows with green and purple shadows.

  Mobile

  

  I tried changing -crf and -b:v values to their max but nothing happens.

  webM file : http://d1pnsuxwa0it39.cloudfront.net/uploads/comments/webm/4673555.webm

  edit :

  also I can see webM files on some other sites fine. I think this has to do something with the way I convert files.

  edit :

  I have tried another code I found on stackoverflow but still the same.

  ffmpeg -f gif -i infile.gif outfile.mp4

  EDIT :

  If anyone think this has something to do with the way I installed FFMPEG, I followed the steps on FFMPEG official docs.
