 Posted: Thu Mar 20, 2003 1:22 pm Post subject: A Going Away Present - Real Audio Ripping with Esound. |
 |
|
I haven't been very active around here lately, and soon, I may find myself without access to a linux desktop for quite some time. A friend recently asked me if Linux had anything like the windows program "Total Recorder", to allow him to listen to Real Audio streams while he was offline, and I drafted this script in response. I thought someone here might be able to use it.
$HOME/bin/realplay:
| Code: | #!/bin/sh
filename=/tmp/esddata.stream.$$.raw
esdmon $filename &
/opt/RealPlayer8/realplay $1
killall esdmon
oggenc -r $filename -o ~/realgrab-`date +%s`.ogg
rm $filename |
No guarantees, as usual, but it seems to work alright for me, and esdmon seems to intelligently omit silent areas at the beginning of the recording. To set it up, you'll need to tell RealPlayer to use Esd for its output, and try to get your other esound applications to shut up ( I don't usually use esd, so this is easy for me ). Of course, you'll also need oggenc, but you could substitute lame or bladeenc with command line switches as appropriate. 
Goodbye, Gentoo, and beloved Gentoo Community. I won't forget the good times we had together.

For anyone wondering, I think the best reason to have RealPlayer installed is for the Seeing Ear Theater at Scifi.com
http://www.scifi.com/set/
Both the City of Dreams material by JMS ( Bab5 JMS, Yes ) and the Tales from the Crypt stuff are fantastic. The rest of it is great as well.

| vsound also works quite well. Remember that for Internet streams you need the -t option. |

ok. I made the script, but using lame instead of oggenc and the script is as follows...
| Code: |
#!/bin/sh
filename=/tmp/esddata.stream.$$.raw
esdmon $filename &
/opt/RealPlayer8/realplay $1
killall esdmon
lame -r $filename -o ~/realgrab-`date +%s`.mp3
rm $filename
|
I ran the script with the direct link to the real-audio stream I wanted to record...
| Code: | puggy@aragorn puggy $ sh realrip.sh http://www.ninjatune.net/solidsteel/getreal.php?file=solidsteel/mar03/03.03.17_1.rm
|
the real audio stream plays and I can hear it perfectly. I then shut realplayer after 60 seconds or so...
lame then encodes the output, but when I play the output mp3 file (which is the correct length) its just noise. Am I being stupid here?
The output is...
| Code: | puggy@aragorn puggy $ sh realrip.sh http://www.ninjatune.net/solidsteel/getreal.php?file=solidsteel/mar03/03.03.17_1.rm
opening socket, format = 0x00001021 at 44100 Hz
realrip.sh: line 5: 8224 Terminated esdmon $filename

Using polyphase lowpass filter, transition band: 15115 Hz - 15648 Hz

Writing LAME Tag...done |
I have set realplayer to esound output.
I noticed that in realplayer it says that esdmon must be running but I see the script both starts and stops esdmon.

If you're stupid then so am I because I could never get that to work quite right. That's when I found vsound, which doesn't allow you to hear the stream when you're recording it, but it actually sounds intelligible when it's finished encoding. There is an ebuild for vsound. |

Ok. trying to get vsound to work now...
| Code: |
puggy@aragorn puggy $ vsound --file=NTune.wav -v -t http://www.hyperreal.org/music/artists/orbital/visit1.ram
Output file: NTune.wav
Temp AU file: ./vsound15233.au
About to start the application. The output will not be available
until the application exits.
/usr/bin/vsound: line 163: http://www.hyperreal.org/music/artists/orbital/visit1.ram: No such file or directory
Missing file ./vsound15233.au.
This means that the libvsound wrapper did not work correctlty.
Here are some the possible reasons :
- You are trying to record a stream (RTSP or PNM protocol) from
the internet. You will need to use the --timing option.
- The program you are trying to run is setuid. You will need to
run vsound as root.
- Vsound was not properly installed and hence won't work at all.
|
Tries running as root. no difference. Also tried a couple of other streams which had the same response. Also tried downloading the .ram file from a site and running vsound with that parameter on the offchance. but just get
| Code: |
root@aragorn puggy # vsound -v -t visit1.ram
Output file: ./vsound.wav
Temp AU file: ./vsound15274.au
About to start the application. The output will not be available
until the application exits.
/usr/bin/vsound: line 163: visit1.ram: command not found
Missing file ./vsound15274.au.

with that.
Any suggestions?

Your syntax is wrong. You have to tell vsound which application to use to open your stream, and you should be able to run it as a user. In your case, the command would look something like this:
| Code: | | vsound --file=NTune.wav -t realplay http://www.hyperreal.org/music/artists/orbital/visit1.ram |
Of course, this just outputs to wav. If you wanted to automatically convert this to an MP3 or other format, just write a script around it. |

ahhh. I started off thinking this, but then I looked in realplayer and there was no option to choose vsound as the output so I assumed vsound must be able to open the stream as well.
Doh!

It really does. Big kudos to the authors. The best way for doing this same thing in Windows requires buying TotalRecorder, which I did, and it works great, but free is always better.
