Recording Streaming Video-Audio

I'll second Adam's recommendation of Audio Hijack Pro. I have found it to be
a very useful and easy-to-use programme.

If the streaming video is in RealPlayer format, it is possible to use the Terminal and MPlayer to save the stream to a local file. I've attached some instructions on how to do this that a friend of mine wrote. They should provide enough information to get you started (see section 2.1). Note that this document concentrates on capturing audio streams. However, the method works just the same for capturing video streams. The only difference is that the 'rtsp' address will point to a file called something like 'filename.rm' instead of 'filename.ra'.

As a further note, there is an easier way to discover the stream's URL address than the one outlined in the document (steps 2 & 3 in section 2.1.2) -- simply ctrl-click (right-click) on the RealPlayer control area (where the play/pause button is) and there is an option to 'Copy stream URL' or somesuch.

Finally, to save me needing to remember the mplayer command, I created a short script (below) and called it 'dumprm'. Now whenever I want to capture a stream, I go to the terminal and type in:

dumprm RealMedia_stream_URL local_file_to_save_to

Hopefully this makes some sort of sense.

- - - - Start Script - - - - #!/bin/sh if [ $# != 2 ]; then echo 1>&2 "Grabs a RealMedia stream (audio and/or video) from the \ internet and saves it as a local file." echo 1>&2 echo 1>&2 "Usage: $0 RealMedia_Stream_URL Output_File" exit 1 else mplayer -prefer-ipv4 -dumpstream "$1" -dumpfile "$2" exit 0 fi

- - - - End Script - - - -

Firefox with appropriate plugins can save practically any stream.

:) There are more.

I use the first, myself, but have no allegiance to it; it's merely
the one I installed and it seems to work.

That depends entirely on the format. You *could* buy Snapz Pro X and record a video of the video playing in a browser window, but that would probably not be helpful.

What's the video format? If you can figure out the URL of the content, and it's a downloadable file (even if they don't offer an explicit download option, you might be able to grab it (I use "curl -O http://whatevertheurlis" for this purpose frequently). To look for the URL, try View Source in your browser, and look for the text of the link to locate it.

If it's FLV (Flash, like YouTube), apparently MPEG Streamclip can do it. There are other tools for other formats.
