Is there any likelihood of :
1. Matrix surround decoding of 2.0 matrix surround (i.e. Dolby Surround) encoded 2.0 AAC/AC3/E-AC3 audio AND correctly flagged in metadata to PCM being implemented. (ffmpeg currently doesn’t have a suitable filter, but MythTV does) This would require a Dolby Surround 2.0 to 3.0/4.0 or a ProLogic-style 2.0 to 4.0/5.0/5.1 style decoding algorithm to be implemented.
2. 2.0 Matrix Surround AAC or AC3/E-AC3 audio being decoded AND re-encoded to Dolby Digital 2.0 (NOT DD5.1 and NOT PCM 2.0) with the correct metadata preserved/generated to trigger off-board AVRs to decode using ProLogic/THX etc.?
Either or both would be amazing, though I realise 1. may require ffmpeg developer support?
