I don't know if this is just me, but now when testing with a downloaded mp3
file and just one audio stream, I get the same errors after about 5-10
seconds(!).

ffmpeg -loglevel debug -max_interleave_delta 15000000 -rtbufsize 128000k
-threads 0 -re -i "http://dl.soundowl.com/4uri.mp3" -codec copy -s 720x576
-q 10 -shortest -f mpegts out.ts

    Last message repeated 3 times

Can anyone else test this one please? I am using the latest ffmpeg compiled
on linux quad core, CPU load is low all the time.
