YouTube Audio problem

Hi

when I downloaded the video below

[www.youtube.com]

the 360p version has sound

the 480p vid is completely silent. (maybe remux issue ?)

thanks..

Works fine for me, tested with VLC and SMPlayer. Here's the media info, I can't paste it here because the forum code can't handle some character sets.

Anything in the log?

can you actually hear the voice on 480p vid ?

I loaded it into goldwave (sound editor),

the audio track is completely blank , no wave form at all..

I can upload the video to dropbox if you want to take a look at it..

Yes, I can hear the sound.

Yes, please upload it.

Here is mine : [drive.google.com]

Have you tried to download it again? Maybe it's temporary problem.

Also, what do your YT plugin settings look like?

One oddity with this particular video,
both on the youtube on-line player
or when playing back the downloaded
clip (with FRD - or other downloader)
in a software player is that it appears
THERE'S (practically) ONLY SOUND
ON THE RIGHT AUDIO CHANNEL.
I do have my laptop connected to a
Hi-Fi System and this is easily perceived...
No clue if this audio peculiarity has
anything to do with OP's issue...

Hi:

Hello

Just downloaded and unrared -
your file DOES HAVE an audio stream
inside the MP4 container!
I am on Windows Vista SP2 x86 and
by probing your file with MediaInfo
you can see for yourself in the attached log.

If you play back the file with Quicktime
(for Windows) v7.7.6 (latest), it is indeed true
that no audio is reproduced.
But if you play back the file in any decent MP4
player (VLC 2.2.1 / MPC-HC 1.7.8 / MPC-BE 1.4.4
and others) you do get audio BUT ONLY FROM
THE RIGHT CHANNEL, as I have posted previously.
The original file uploaded on youtube must've been
faulty, since the same audio behaviour is exhibited
on the youtube page itself...

AFAICT, there's nothing wrong with the FRD youtube plugin.
For your convenience, I demuxed the audio
stream from the MP4 file with FFmpeg (it's a raw
ADTS file with .aac extension), and then, using again FFmpeg,
I have transcoded it to a mono MP3 file, which I attached.
(NB: I have edited out the silent parts in the start & end,
to reduce file size...).
Enjoy your chant!

Regards

Hi:

Thanks for the info, it's very help
looks like it's a player issue,

but strange enough, the 360p version does have sound
on my system, but not 480p ,

and when I loaded both clips into goldwave (sound editor) ,
the 360p has waveform only on right channel.
but the 480p is complete blank, it seems that even
goldwave can't get the audio from 480p.

so maybe 480p is AC3 or something that's not just 2 channel stereo ???

As stated in mediainfo (by me and TVjunkie) it's AAC and stereo, but the left channel is completely flat.

Here is the waveform from audacity (sound editor) :


So I think your video player and sound editor need to be updated
