  avfilter/asrc_flite : Don't segfault when using list_voices option
  Could also happen if initializing flite failed* or if an unknown voice
  
  has been selected or if registering the voice failed.
  * : which it currently can't, because it is a no-op.

• After a while of being idle, my bot, hosted on CentOS 7, can no longer find ffmpeg and requires a restart

  14 août 2019, par Liam McMillen-Meyers

  So I have a discord bot running with discord.js on a CentOS 7 machine. After a while (I’m not exactly sure how long) it will start throwing errors when I try to play a song, saying it can’t find ffmpeg, except that ffmpeg is installed. After I quickly restart the bot it works fine again.

  I genuinely have no idea what causes this, I have a little experience with CentOS but I’m by no means an experienced user, is it something I did when it installed ? I have tried searching for answers online but I can’t find anything

• Anyway to get current playtime of a song ?

  2 décembre 2019, par Blue Lightning

  So this is the basic voice that I’m currently using to play music through my bot. I’m streaming the audio (using the stream async function) opposed to downloading it local. Anyway I can get the current playtime of the song that is being played ?

  So whenever someone plays a song, they can, whenever they want, see how much of the song they played through already.
