I just bought a Toshiba Camelio S20 which records to AVI containing FF AAC & H.264 AVC (variable bitrates).
I can playback recorded files fine on my PC. However I don't get sound in Sony Vegas or MS DVD Movie Maker.
I researched and found out about demuxing the AAC and converting it to WAV, etc. I found this a lengthy process. Muxing the WAV & AVI back together is a bit troublesome due to the VBR (or something).
I was wondering whether anyone know a batch/tool to demux, convert the AAC and remux the AVI... so effectively I can just simply import the AVI into Sony Vegas or MS DVD Movie Maker, etc. without separate audio stream hassle?
I have used AVI-Mux_GUI-220.127.116.11 VirtualDub and both gave me out-of-sync audio with silent gaps, etc.
AviDemux says the video might be using B-frames as keyframes? so will get stuttering... and if I rebuild the P-frames... then it gets out of sync.... :S

Previously I used https://forum.videohelp.com/threads/267680-Demuxing-aac-file-from-AVI this guide (the guys script works for ffmpeg).. so ffmpeg must be able to demux aac okay. Plus I can play the original video file in Windows with sound. Just no sound when I try to convert....
avidemux before and didn't like it... but I just used it again and it works! Well, aslong as I convert the audio to anything other than AAC then I get a working sound stream that is recognised in Vegas 9.0. If I Copy or use AAC in audio convert then I get no sound in Vegas 9.0... even though I get sound by playing back normally in WMP or MPC....
I was thinking about rebuilding the i-p frames... but not doing so didn't make any difference...
