v2.3.0

Added

• Alpine Linux support (#164).

  results in wrong frame size being detected except for 44.1kHz.

  segments should be excluded from peak bandwidth calculation per HLS
  specification.

  accumulated and became noticeable after running the live packaging for some
  time.

Changed

  increase in binary link time.

  mpd_generator).
