Unable to play rtsp URL embedded in rm file

[Stefan Gründel]

On amazon's website you can listen to some of the CDs offered, the URLs are of the form *.rm, when you select the link in konqueror and open it in amarok using xine-lib, amarok says "Fehler beim Laden des Mediums - Es gibt keinen Audio Kanal" (my translation: "Error loading medium - an audio channel does not exist").

When you download the .rm file and open it in a text editor it looks like

 rtsp://67.135.228.120:554/real.amazon-de.eu2/phononet/B/0/0/0/A/8/A/W/V/O/01.10.rm?cloakport=80,554,7070
 --stop--
pnm://67.135.228.120:7070/real.amazon-de.eu2/phononet/B/0/0/0/A/8/A/W/V/O/01.10.rm?cloakport=80,554,7070

When you open the rtsp-URL directly in amarok, the stream get's played just fine.

Sorry no-one ever got back to you. Can you confirm if this is still a problem? Can you try in Jaunty please? Thank you.

Just tried in Kubuntu 9.04, it still doesn't work. I don't get an error message, but the stream (http://www.amazon.de/gp/music/clipserve/B00000DG29001001/1/ref=mu_sam_ra001_001) isn't played either.

I think you can close this ticket anyway, as when I reported it using KDE 3.5 and amarok 1.4, KDE people told me to report it in xine-lib because that's the library responsible for that behaviour.

Jaunty contains KDE 4.2 / amarok 2.0, and as this is a completety rewritten software I'm not sure if it still uses xine-lib anyway. I'll simply report it again under Kubuntu and see what the developers will say there.

Thanks, Stefan

I do not believe it is a KDE bug, it probably is xine, as I just tried the link you gave in totem, and had the same result, looked like it was *trying* to stream it, but no error message.

I shall mark this as Confirmed and set this to Medium importance - this is quite a problem in a core application - any user using Amazon (assuming quite a few) will not be able to play these streaming RealMedia files. Note: I have ALL Medibuntu codecs installed - probably xine at fault.

Confirmed in Karmc + Medibuntu.

The same streams that cannot be played in Amarok are played fine by mplayer with the ffcook codec in ffmpeg.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.
There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test the current Ubuntu version (10.10). If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect <bug #>, and any other logs that are relevant for this particular issue.

I can't really reproduce this error, as Amazon has changed the listening interface. In Kubuntu 10.10 using Rekonq or Firefox, the music is directly played in the respective browser.

The original link in comment #2 still resolves, but I cannot play it using VLC or Mplayer or Amarok. So from my point of view this can be closed, the original error might still exist (but I don't know where to get an *.rm file containing an rtsp URL), but the original use case (listening on Amazon's web site) now works.

The URL <http://www.radio.rai.it/live/radio3.ram> is a RealMedia link to <rtsp://live.media.rai.it/broadcast/radiotre.rm>. Could someone with Ubuntu 10.10 test it?

[xteejx (xteejx)]

I can confirm that this seems to be fixed in Natty. The RealMedia RTSP URL above works in the default media player perfectly fine. Marking this as Fix Released.
