#948: No audio in output when the audio starts late in VOB file
-------------------------------------+-------------------------------------
Reporter: | Type: defect

-------------------------------------+-------------------------------------
Here are the details about the issue:
Source: .VOB file extracted from DVD decrypter (first chapter of the
movie). This has one video stream, one audio stream (AC3 5.1).
Issue: When I try to encode into any format, it reports 0 channels in ac3
stream and there is no audio track in the output. I tried with directly
copying the AC3 stream, encoding AC3 to AAC, using analyzeduration option
etc.,
But, the same file is working fine when I use Handbrake, MEncoder.
Source to download: You can download .VOB file here:

Please let me know, if you need any more information.
I have been searching for a proper encoder from past 2 months and couldn't
find a working solution.
My requirement: I have several DVDs and want to convert them into
MP4/M2TS/TS files with 2 audio streams (AC3 5.1 and AAC). Also, want to
add watermark on the output. Tried different encoders, but nothing is
working as per my requirement.
Thank you for your time!
