[QUOTE="paony, post: 493305, member: 87798"] [b]realtime aac -> ac3 transcoding[/b] I have the same problem as scott. I have set up the following direct show filterchain (only audio branch shown) for mkv files with aac 5.1 sound: media splitter -> ffdshow audio decoder -> ac3filter -> audio renderer (see attachment) I have checked this with graphstudio. It also runs runs like this in windows mediaplayer. but in mediaportal it allways ignores the ac3filter and uses the following scheme: media splitter -> ffdshow audio decoder -> audio renderer this happens even if i check video -> video player -> automatic decoder settings in mediaportal configuration. It seems that mediaportal does not setup the direct shown chain according to the merits, even if the above configuration option is set. I suppose it would work if ac3filter would support aac input natively (as it does for mp3 and aac): media splitter -> ac3filter -> audio renderer but unfortunately it is not supported and so ffdshow audio and ac3filter have to be chained. It would be nice if mediaportal could support this in the future:), in the meantime i have to use ms mediaplayer:( to get 5.1 sound with aac best regards Stefan [/QUOTE]
