Sorry for the missing details... (will provide them now in greater detail)
Please see the output of "ffmpeg -i share.mp4 -sameq output.mp4"
here: http://pastebin.com/n40GJG3s

Playing the video with ffplay shows correct audio
and video BUT with a kind of slow motion for
the first several seconds.... (audio and video are
in sync after that)

Plays the video but here, audio and video
are NOT in sync....

I obtained the share.mp4 video file with the following command:
ffmpeg -i rtsp://url.mp4 -vcodec copy -acodec copy -ss 0.00001 share.mp4

Thats the URL (rtsp://url.mp4) I use: http://pastebin.com/JWdXKiZc

Note: I need the -vcodec copy and -acodec copy options since my
system is too weak to perform heavy calculations during download... (so
please consider
this as necessary)

One interessing aspect: When I execute the "ffmpeg -i share.mp4 -sameq
command, ffmpeg responds with:
"multiple edit list entries, a/v desync might occur, patch welcome"

Could this be a part of the problem and how to resolve the issue???

It would be great if it would be possible to download the correct stream
the -vcodec copy -acodec copy options...

Excited to hear your thoughts...
