rtmpdump : Download may be incomplete

[jafar2049]

Hello,

I've already downloaded several videos by using rtmpdump command and I never had any problem. Since this morning, I try to download a music concert from the website : citedelamusique.tv
It's a HD video and I believe that the file is quite big. When I run the command in terminal during several minutes, everything works as usual but then I get the following message:

INFO:   sampletype            mp4a

Download may be incomplete (downloaded about 12.20%), try resuming

So the message says that Download may be incomplete. After a bit googling I found that there is a --resume option that may tackle this problem. Yet the same thing happened several minutes later, besides it asked me to specify a value for --skip (I didn't know what to specify).

Does rtmpdump have any problem with very large streaming (the concert is about 1 h 40 min) or there is a problem in my command?
This is exactly how I run rtmpdump in order to download the specified video

rtmpdump -o Pleyel-20120420-Brahms-Sy-02And04.flv -y mp4:PLVI/PLVI000178200/PLVI000178201/PLVI000178201_00_HQ.mp4 -n dcfms35-202.streamedia.info --app VOD --resume

Any idea?

Thanks in advance,
