Im using this command:

C:\rtmp\rtmpdump.exe --live -b 36000 -r "rtmp://url" -o "c:\rtmp\filename.flv"

or

C:\rtmp\rtmpdump.exe --live -r "rtmp://url" -o "c:\rtmp\filename.flv"

or

C:\rtmp\rtmpdump.exe -R -r "rtmp://url" -o "c:\rtmp\filename.flv"

Please Help,Thanks

Your dump is fine. The video has sound /(effect?)/issues.

Thank You transporterfan for the reply,
When I live streaming the video using mozila firefox, everything is fine. the audio,music,and the visual.
But when I download it using rtmpdump or IDM,always have that problem.

Maybe this can help, RTMPdump Metadata Info:

Nothing can 'help' if the source video is glitched. Maybe it's an anti copying device. It's annoying enough to stop me wanting to download it.

Hi ,

Can you try :

ffmpeg.exe -re -i "rtmp://url" -vcodec copy -acodec copy -f mpegts pipe: "c:\rtmp\filename.flv"

Cheers .
