Support for AV01 video codec

[Idea by Discord User “CowEye”]
If SM5.3 support AV01 video codec, it would be much easier for Stepmakers to make simfile

  1. Download the YouTube video you want to make a simfile from
  2. The downloaded format is AV01/AAC .mp4
  3. Split video and audio with ‘mkvtoolnix’ program, which is multiplatform (takes less than 20secs)
  4. convert AAC audio to .ogg with Encoder (takes less than 20secs)

In this way, Stepmakers don’t have to use encoder for their BGA
and BGA quality would be much higher since it’s Youtube-Quality
