September 1, 2026: Multipurpose Encoder v3.2.6 released

Multipurpose DirectShow Encoder 3.2.6 is available.

  • Changed: rate control rewritten. Min and max bit rates are now always applied (they used to be silently discarded when lower than the internal default target) and the target is fitted inside them. A VBV buffer is derived from the max rate, so IDR peaks are bounded: a network output (UDP, RTMP, SRT) specifying a target rate but no ceiling now gets one; local file recording keeps the plain ABR behavior.
  • Changed: negative integer settings uniformly mean “not specified”, like 0.
  • Fixed: random deadlock between the capture threads and the muxer during a recording or a record-to-new-file switch.
  • Fixed: the audio capture thread no longer waits behind a video frame being encoded.
  • Fixed: PTS staircase and shortened duration after a pause / resume.
