GKnot and AAC

[vio_man]

It would be nice to be able to mux AAC into AVI using GKNot. Now that AviMux GUI supports AAC muxing, GKNot could support AAC in addition to MP3.

[Tuning]

Do equations do anyhting ?
EQ1. GKnot only uses VirtualDubMod for muxing!!.
EQ2. VirtualDubMod does not support AAC muxing.

EQ1= Never going to change.
EQ2= may be false in near future.

SO everything depends on EQ2.

PS: Bugg VDM developers and sometimes you may get its support. (only in sourceforge tracker).

GKnot could start using AviMux GUI :D

[xistan]

Or you could...

seeing how may ppl have issues with files muxed with AViMux on their standalones (in hardware forum) I'm very grateful at the moment that I'm not using it.

Would any hardware player currently play AAC-in-AVI at all?

[bond]

no player plays aac atm afaik

but perhaps aac-in-avi has the second greatest chance to have a future compared to mp4 imho on standalones

why not do MP4 output and use AAC for the audio? After the video is encoded, all that's left is the audio - easy for FAAC to encode. Then just a quick MPEG4ip batch file later, an MP4 file comes out!

@len0x: the problem has been fixed btw. It was a severe bug in the liteon firmware: it didn't know that 10,000,000/400,000 is equal to 25/1

EDIT tried to divide 10,000,000 / 25 without a calculator....

Yes, a MP4 file comes out. But if you were using DivX5 with b-frames it will be a non-spec compliant MP4 file, as mentioned many times before in the XviD and New A/V formats sections here.

There is currently only one solution to make a spec compliant MP4 file from a DivX5 AVI, and that is using 3ivX MP4 muxer on DirectShow. It will detect the packed bitstream, remove dummy frames and reorder the frame accordingly ....

[riggits]

I use the 3ivx muxer exclusively now, and I have never used DivX b-frames because my testing indicates that they decrease quality extensively, while adding a decoding penalty even on high bitrate encodes. The easy fix is to disable B-frames for DivX encoding in GKnot. I don't think anybody would miss it. Of course, I also prefer the DivX free codec instead of the Pro versions, and prefer the XviD codec to everything else :D

hm a gknot based on dshow (not vfw) would be an idea :D

this would allow output in all containers (avi, mkv, ogm and mp4), there are also mp3, aac, vorbis, xvid, 3ivx and nero digital dshow encoders

tough i doubt that len0x will totally rewrite gknot :D

@bond : Actually, there is already a Gk version for OGM and MKV containers, but ThegLouch, the creator, hasn't time to continue the developpement...

Here's the link for this version : http://members.fortunecity.com/bdreve/gk/ (version GL)

GK_gL version can mux Vorbis/DTS/AC3/MP3/MP2 audio files with a XviD/DivX video files, Chapters (*.txt) and Subtitles (*.srt).

lol
It's version 0.29 alpha from main CVS branch of GK. It does indeed work with OGM and MKV (not stable enough though). Those ppl subscribed to gk-alphas list were able to use this version starting from summer...

P.S. but as nither me nor tHegLouCh has time to support public version of it now it was never released publicly.
