Subject:   Invalid RealAudio(RM)files after an  mplayer -dumpstream session

Is there a "fixup" tool or something faulty rm files?


I earlier got the response that mplayer -dumpstream... can dump a
RealAudio file to disk and I tried it with very good result.

I then created a batch to download a whole lot of RM streams to disk
which took some days ofcourse.

But today when I wanted to transform the streams to PCM I realise that
the dumped streams must be errenous in som way, I can't even play the
streams as they are, though mplayer does recognise them.




An example stream could be 
"rtsp://lyssna.sr.se/P1/Sommar/Sommar-040616.rm"

which I dumped using 
"mplayer -dumpstream -dumpfile sommar040616.rm
rtsp://lyssna.sr.se/P1/Sommar/Sommar-040616.rm"

(It's long (90 -120 minutes) and takes up 20mb)
