We currently use unreal media software on Windows. Although the live and media server software is very good, the archival software has proved unreliable at best, not recording when scheduled, randomly stopping recordings etc. I personally think this is more to do with Windows than the actual software which is why I am looking for something that will perform the same task on Linux, CentOS to be exact. That is software that will connect to the unreal media server and record the video streams.

I have however found what appears to be the ideal solution, mplayer -dumpstream
For some reason I when I try to use mplayer -dumpstream -dumpfile test.wmv mms://x.x.x.x:5119/alias
I get an error, "mplayer has crashed, this should not happen."
When I use the command in the format mplayer -dumpstream -dumpfile test.wmv http://x.x.x.x:5119/alias
it does record the stream to test.wmv but it states that the stream is not seekable and the recorded file will not play in Windows media player or VLC etc.
Is this because it is a raw video file? How can I make it record a wmv file that will play? Is this something to do with codec options?
The streams to be recorded are wmv format.

Probably a bit hard to implement - but AFAIK the get_iplayer script uses it to convert video flash into mp4 formats, successfully.

The OP is wanting to use not-Windows.

I have been able to record the video streams using mplayer -dumpstream but the problem is that the recorded streams are not seekable. This is a must for the application. Anyone know a way round this?

cvlc "mms://x.x.x.x:5119/alias" :demux=dump :demuxdump-file=filename.wmv
If you have a recent enough mplayer, you could try different mms code (from ffmpeg) by doing:
mplayer -dumpstream -dumpfile file.wmv "ffmpeg://mmst://x.x.x.x:5119/alias"

I am on a one man mission to prove to the company that Linux will serve many of their needs better than Windows. This would be a big step but unfortunately their love for Windows and fear of Linux appears to be quite unshakeable atm. I think with Linux it is a fear of the unknown for them and they have just accepted the continous "firefighting" with the Windows systems as a way of life.
Anyone with experience with Linux knows different as we know that once we get it working it will just keep working.

I am going to attempt to patch VLC - comparing the dumped file with the fixed file re-muxed by Windows Media Stream Editor (part of Windows Media Encoder) - there are just some extra seeking indexes at the end of the file.
Edit: It may not be possible, since while streaming, seeking would be handled by asking the server for a different position in the video - and there wouldn't be any purpose in sending the indexes after sending all the video data. So the index has to be added after - and VLC seeks much nicer with the fixed file.
