Hi All, Untill recently i was able to use graph edit for converting any AAC audio to AC-3. Primarily because AAC audio in an AVI/TS/M2T file is somehow not played properly by my PS3 , which is my main media machine tio stream any kind and every kind of playable content. The AAC demuxed from any MKV is simply to be dragged and dropped in the GraphEdit work area and it would construct a filter graph for the audio decoding chain, which I can later amend manually by ffdshow-directshow filters to read and output the AAC file into an AC-3 file. Everything was working fine, when suddenly after quite sometime i needed to convert an AAC file and when dragged and dropped to GraphEdit, it displays an error as shown in the attached image file. Can anyone guide me as to what am I doing wrong. I have not uninstalled any of the previous directshow filters I have and all the settings are intact. I guess i may have installed dBpoweramp for testing purpose but it should'nt make any working program go haywire. Any ideas and help is highly appreciated. Regards, Myself
Well i have got FFDShow installed and working properly and AAC is enabled via ffshow as shown in these images. Anything else you can suggest or guide, I would be happy to do that. I using demuxed AAC audio stream because I want to covert it into AC-3 and remux it again in the H.264 video stream from the MKV file to enclose it in a M2TS container playable on PS3 via the DLNA server. My graphy exactly used to look like the one you have posted and everything was fine. But suddenly it has stopped working although I did not change any existing settings or something. Thanks.
For some AAC files (shown as ADTS)that wont load in Graphedit, you can install 'AAC Parser' then drop the file into Graphedit. Scroll to the bottom of the page in the link. http://www.inmatrix.com/zplayer/formats/aac.shtml
Thanks for helping. But unfortunately the problem still remains. I also tried installing the AAC parser from http://www.inmatrix.com/zplayer/formats/aac.shtml but still the file cannot be opened in GraphEdit. The source MKV file however plays fine with JetAudio. And in Jetaudio the ffdshow is happily used to decode the aac source audio. But when the separate AAC stream is imported in GraphEdit, it somehow rejects it. It was however working fine and I did use it numerous times. I tried another suggestion given by a user on Doom9, I imported the source MKV in graphedit and then deleted the Video Decoding chain. Then deleted the default directsound device from audio decoding chain and inserted file write at the end. I am trying with it right now and maybe it would render a compatible AC3 file. Nonethless I am happy if it works the alternate way, but would still like to learn what has gone wrong. Thanks for support.
