"No Audio Track" converting MPEG2 (originally .tivo)

[Jello]

Howdy,

So here goes...

I pull .tivo files off my tivo using Tivo's TivoToGo software. I then strip the Tivo BS off these files using a utility called DirectShow Dump (http://prish.com/etivo/tbr.htm). DirectShow Dump essentially strips off Tivo's layer of proprietary junk to make the video an mpeg2. These mpeg2 files are viewable/audible on my local computer without a problem (Windows XP SP1), as well as another local computer (Windows 2000, SP4).

When I try to load these files in AGK, though, they take several minutes to load, and the only option for audio is "No Audio Track". Based on what I read in this thread (http://forum.doom9.org/showthread.php?t=88841), I'll post screen shots of AGK as well as the results of bbSummary when I run it on a test file.

I'm wondering why bbSummary doesn't see an audio stream. I'm able to convert other mpeg2 files that I've downloaded, so I'm wondering what specifically might be wrong with the ones I've pulled from my Tivo.

Wondering why bbSummary doesn't see an audio track when I can listen on my computer.

Hi and welcome to the forum.

Practical hint: you can edit your previous mail, no need to make new one(s) that can be taken as bump and then get under rule 11 or 12 ;)

Now I see nobody's responding so nobody has your specific problem (I don't either) :(

I can only share what my searches for agk+tivo/autogk+tivo returned:

Discussion about mpeg tools like mpeg2cutter, pvainstrumento, projectX etc...

If I understand well you mpeg2 file may not be compliant so audio is not recognized in AGK, try these tools maybe you'll have a more compliant stream that you can feed in AGK?

Anybody else?

Post a link to a chunk of the MPEG2 and I will tell you if it has decodable audio, etc.

I have exactly the same problem.
I can workaround it by doing the AutoGK tasks manually, but it's a pain. I would rather encode in batch with AutoGK.

Hi!

As an experiment, play the file with "VLC player" - and from the audio track listing, see if the audio shows up as "Track 2" instead of "Track 1". If so, you can fix it with either "VCDEasy" or "VCDGear" (Honestly, I've forgotten which of the two works for this ;>} )... (Yes, it will work with an MPEG-2 file)

Thanks, setarip_old. I'll give it a try.

The frustrating thing about it is that since bbsummary doesn't recognize the audio, AutoGK doesn't work.
DGIndex can see the audio track and correctly identify the offset.
I can manually convert the audio de-muxed by DGIndex with LAME.
Then I create an AVS to read in VDubmod.
I can at least batch convert from that point in VDubmod, but I have to be satisfied with 1-pass.(which is ok)
Seems that if bbsummary were updated there would not be an issue.

Thanks, setarip_old. I'll give it a try.Let us know if it works for you ;>}
