How to export the audio stream in Graph Edit?

[bozitaai]

Dear all,

filter name : 3ivX Pro [version D4 4.5.1] [Encoding]
fucntion : DirectShow encoder for AAC audio.

This directshow filter was installed and used to encode my audio stream with AAC format in Graph Edit. The audio can be played by using "Defaule DirectSound Device", however, I want to save the audio stream into file. I tried to use the directshow filter "File Writer", but it doesn't work. Anyone know how to export the file in Graph Edit?

Thank you.

"File Writer" will only connect to the "AVI Mux" filter, thus it can only write AVI files. What you need is a filter that can write AAC files, but I'm doubtful that such a thing exists. :(

IIRC Dump filter can write AAC stream to file.

Connect the 3ivx Audio Encoder to the 3ivx Media Muxer then to the File Writer with a .mp4 file.

see http://www.3ivx.com/support/windows/encoding/ge_audio.html

Dump filter is included in this (http://www.digital-digest.com/dvd/downloads/graphedit.html)package (in case u only got the graphedit executable).

I tired to use the Dump filter to write AAC stream to file. What methods can playback this audio file. When drag & drop this audio file into a GraphEdit, the GraphEdit doesn't allow it. That's mean the structure of this audio file is incorrect!?

Thanks Stux. I connected the 3ivx Audio Encoder to the 3ivx Media Muxer then to the File Writer with a .mp4 file. It works, but I need to get AAC audio stream rather mp4.

Any muxer(s) can multiplex the H264 video stream & AAC audio stream together?

H264 stream from "Moonlight H.264 Video Encoder"
AAC stream from "3ivx Audio Encoder"

Thanks

The dump filter should work to write an AAC stream to file, but it will be a raw AAC stream, which is almost useless.

Much better to take the MP4 and then use some other tool to extract an ADTS stream from the MP4 file.

Most modern AAC tools handle MP4/M4A anyway.
