Hi,

I'm writing a program that runs RTMPdump (http://all-streaming-media.com/record-video-stream/rtmpdump-freeware-console-RTMP-downloading-application.htm).

How do I determine the filesize of an RTMP stream before I save it with RTMPDUMP?

Cheers,
Bill

You don't.

The RTMPDUMP program contains the switch -W which does that calculation for you automatically.

And all the parameters outputted by the -W switch are saved automatically in a file named .SWFINFO in your RTMPDUMP directory.

The information distibuted with the standard release versions of RTMPDUMP explains what url to specify in the -W switch, using this format:

-W "http://{URL}"

Here's an example -

-W "http://www.bbc.co.uk/emp/9player.swf?revision=18182_20020"

I was hoping to run rtmpdump minimized/hidden and use a progress bar on my form to track the download (eg. 25MB of 257MB downloaded).

Isn't it possible to get the filesize before starting the download?

RTMPdump (http://all-streaming-media.com/record-video-stream/rtmpdump-freeware-console-RTMP-downloading-application.htm) v2.1 displays that information in the standard console window handling the rtmp download.

You must run RTMPdump in order to obtain that information. You cannot obtain information from an rtmp:// url using http:// methods.
