Comment (by streamingguy):

 Hello,

 Thank you for your quick reply! I am very new to FFMPEG and sorry if I
 miss anything in my below details:

 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:
 http://poacric.blob.core.windows.net/$root/TestClip.zip

 Command Used: ffmpeg -i d:\testclip.vob -acodec copy d:\ffmpegout.mp4

 Console output:

 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 proper 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!

 zero audio channels, even though it has 5.1 audio stream.
 > Please provide a ffmpeg command line that allows to reproduce your
 problem (no external libraries please if not necessary to reproduce)
 together with complete, uncut console output.
 > A sample might be needed, too.
