Blu-ray authoring difficulty, Need to remux after correcting audio duration

[llee782]

I already posted this problem to the Toast 10 forums, but I think it makes sense to ask for help here, too.

I have a Hauppauge HD-PVR, Toast 10, EyeTV 3, latest software and firmware updates for all. I can make Blu-ray discs without reencoding in Toast if I click the Toast button in EyeTV and select "Never" in the encoding settings in Toast. The problem is that the output of the HD-PVR never maintains sync between audio and video, so I've developed a method incorporating ffmpeg and sox to make slight adjustments in tempo for the AC3 audio. That means, of course, that I have to work with audio and video separately, which isn't a problem, except that I can't seem to find a way to remux the audio and video so that Toast will accept the results without reencoding. I've successfully remuxed with both ffmpeg and MP4Box to .mp4 files that play just fine in VLC and mplayer, but can't be accepted by Toast (error "unsupported format and cannot be imported"). When I use QuickTime Player Pro, I can create a .mov file, but I can't create a .mp4 file unless I convert audio to aac in audio export options (passthrough choice isn't available for audio), so Toast insists on reencoding any file produced by QuickTime Player. Is there any way for me to put the adjusted AC3 audio back together with the h.264 video so that Toast can author my Blu-ray disc without reencoding the way it does when I click the Toast button in EyeTV? Thanks.

did you try to export as .ts from ffmpeg (andf play with the -itsoffset argument to correct audio begining?)
The ffmpeg's ts is awfull but it can be a good begining to give it to toast (I don't use it so I don't know how it reacts)
eg: ffmpeg -i input_audio -itsoffset 0.46 -acodec copy -i inputVideo -vcodec copy -y output.ts

Thanks. The itoffset wasn't needed, but the output ts file wasn't accepted by Toast either (same error).

One answer appears to be txMuxer. GUI version hasn't been made compatible with Snow Leopard yet, so I learned the command line method. I've only tested with a short clip, but Toast did make a valid BD image with no reencoding.

GUI version hasn't been made compatible with Snow Leopard yet

are you sure?
not an official version but a hacked one (not by me) for Snow Leo

Nope, that one only opens for me in Leopard, not Snow Leopard.

Here's the error output:
dyld: Library not loaded: QtGui.framework/Versions/4/QtGui

oops you are right: I forget to say to install first the qt librairies (as written on the post from the GUI who updated the GUI/tool)
But he changed binary too (Command Line Tool) to avoid the concern with hardcoded fonts in it with SnowLeo. I suppose the binary works without any qt compile (I don't verify I still have qt on my computer )

Yes, it does. Much better. Thanks!
