avconv debug output on misbehaving stream

When trying to download streaming content from the dutch public service
uitzendinggemist.nl most streams cause avconv to stop on a "non monotonically
increasing dts" error.

If I comment out the "return AVERROR(EINVAL);" command on line ~361 in
./libavformat/mux.c I can succesfully download and play the stream offline as
suggested in this comment:

https://bugs.launchpad.net/ubuntu/+source/libvpx/+bug/1191516/comments/5

My suggestion would be to demote the mentioned error to a warning or make it
optional to ignore (all?) errors by commandline.

The full output of below commandline is attached

avconv -v 9 -loglevel 99 -i
