Now that there is a codec section in binary release section on Helix Community that I manage, I realized I can make 'dtdrive' available for download. The package that I built is binary Win32-x86 only, but many of dtdrive's modules and dtdrive itself can be built from source from the Helix Community.
This tool does just about everything and the kitchen sink (except mux RM files, but that may be forthcoming), and I thought it would be useful for the advanced container format users in this forum.
For instance, you can convert AAC-RM to AAC
dtdrive file.rm -W file.aac
AAC-RM to M4A
dtdrive file.rm -W file.m4a
AAC to AAC-RM
dtdrive file.aac -S 1 -W file.rm
AAC to M4A and M4A to AAC
dtdrive file.aac -W file.m4a
dtdrive file.m4a -W file.aac
Demux RM A+V:
Audio: dtdrive -DV 0 -DA 2 av.rm -S 1 -W audio.rm
Video: dtdrive -DV 2 -DA 0 av.rm -S 1 -W video.rm
[-S 1 should always be used when writing out RealMedia file]
+ a whole lot more (conversions, decodes, transcodes, transmux) with a long list of formats (sorry, not Matroska). These were just the minimal set of examples I have tried myself. I am not really giving dtdrive justice by providing so few examples... If something does not work, let me know, but it is more than likely I can not help or explain right away at least.
