[RESOLVED] Error opening MP4 files

Post by jpsdr »

Hello.

A friend of mine gave me mp4 files created by his camera.
I'm unable to open his files, DGIndexNV gave me an error message.
I'll PM you my FTP server informations where you can get one of these files.
Tell me when you have retrieved it.

OK, I have the stream. Feel free to remove it from the server.

I have it fixed but I have to re-test all my MP4 files to make sure nothing broke. The problem is that the MP4 library was assuming that a "meta" box must be an iTunes metadata box. But this box in your file is a Panasonic one, and the formats are not the same. I am just removing handling of "meta" boxes as an initial approach. They are optional in any case and not used for playback parsing.

Damn Microsoft! The Creators Update killed IIS and TFS, so my source control is gone. Now I have to fix that too.

Slipstream 112 has the fix.

TFS is brain-dead.

I ditched Team Foundation Server and got VisualSVN running in less than 15 minutes. Works sweet!

Hello, thanks for the update.

Is it "expected" behavior that the following commande line is stuck and doing nothig ?
DGIndexNV -i 01.mp4 -a -e

Edit
Ok, i have to add "-o 01.aac"... i must said that i wasn't sure, the documentation is not clear about.

Edit 2
My big mistake... :facepalm:
I was too much focuss on my 2 steps 1rst attempt (DGIndex for video, eac3to for extracting/converting audio to wav).
When eac3to failed to handle the file, instead of just adding "-a" to my dgi creation, i was still in "2 command lines mode".
But i have to use ffmpeg because i can't decode aac with eac3to...
Nevertheless, thanks again.

Yes, you are correct. The correct line is:

DGIndexNV -i 01.mp4 -o 01.dgi -a -e

The point is that audio demuxing can only occur during a save project operation. I will add a note about it to the user manual. Thanks for pointing it out.

Aren't there AAC Avisynth source filters, e.g., BassAudio?

There is probably things, but i don't know them. I've been able to convert the aac files with ffmpeg and process my files, so everything is fine.
