  avcodec/jpeg2000 : Move L band scaling from the 9/7f wavelet to quantization stage
  This reduces the number of operations
  
  Its not done for 9/7i as that would overflow thanks to JPEG2000 allowing
  
  32 decomposition levels

• 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.
