1. libavcodec.dll was updated to the version from ffdshow-tryouts version 1837. This fixes decoding of some streams that previously didn't work.
2. Audio demuxing was redesigned so that streams do not need to be present in the PAT/PMT to be demuxed. A Preview operation will show all detected audio streams in the Info display; they do not have to be selected for demuxing.
3. TFF/BFF reporting for field structure streams was fixed.
4. CLI support for audio demuxing was added (-a).
