Consider opening a feature request on roundup.ffmpeg.org

True, I guess this happens on the first receiving problem, if you use another
container (nut), the so-far-recorded file is at least playable. You could also
try the various patches attached to roundup issue 807 and its duplicates.

What does work (I tested 410 seconds), is to use ffmpeg -vn -acodec copy
out.aac, but I was not successful to record video.

Both dumpvideo and dumpaudio do not work for this stream, I have no idea why...

Note that it should be no problem to choose parameters for re-encoding with
ffmpeg to still get a perfect result.
