Demuxing of video

[AIR-Force 1]

I am in search of software that can demux a raw mpg2 Video file with 5.1 surround sound into a separate video file and separate audio in six mono channels representing the original 5.1 sound channels in the original mpeg2 file. The quality of the video and audio must be exactly the same as the original file. I have tried some of the software described in the forum, but most of them don’t want to read the raw file and it is mostly an extremely long procedure using to many different types of converters to get to a single desired output. I have tried DVD Lab pro 2 to demux the file, but it only split the file into a video (*.mpv) file and a single audio (*.ac3) file with 5.1 properties rather than 6 mono (*.ac3 or *.wav) tracks. The speed is round about 30 to 45 seconds for a 1.5GB video clip and speed is of an essence. The reason why I want 6 mono audio channels is to be able to use the files in Avid Liquid 7.2 and reproduce the file to a DVD with the original 5.1 channels. Avid Liquid cannot demux input audio files into anything more than stereo.:thanks:

I know of no one software tool that will do what you ask, but if you use dgindex, it can demux the MPEG2 file into an M2V and an 5.1 AC3. Then you can run the 5.1 AC3 through eac3to (http://forum.doom9.org/showthread.php?t=125966) or besweet to convert it to your mono WAV files.

I tried EAC3toGUI, but this program doesn't allow demuxing of AC3 to 6 mono channels. BeSweetGUI does allow 6 channel mono waves but the bitrate of the output file is not the original 448Kbit but something like 780Kbit (or something) that makes the files extremely large. What command line can I add to bring down the bitrate to 448Kbit? I am unfamiliar with all the command lines in these two applications.

I tried the -ac3enc( -b 448) command:

BeSweet -ac3enc( -b 448 ) -core( -input "G:\Convert\M2U00095.ac3" -output "G:\Convert\M2U00095" -6ch ) but the file stay 780Kbit

If I tried the –ac3enc( -b 448) command like this:
BeSweet -core( -input "G:\Convert\M2U00095.ac3" -output "G:\Convert\M2U00095" -6ch ) -ac3enc( -b 448 )

Then the bitrate is 448Kbit but not in 6 mono files as I intended.

Wave files are lossless, so they require more bitrate than ac3 (which is lossy). A wave file, 48000 Hz mono 16 bits, has a bitrate of 48000*1*16 = 768 kbps. And that's only one wave file.
