[MPlayer-dev-eng] BUG report: Stuck wma->mpeg1 conversion with mencoder using cvs as of 10 minutes ago

[Sam Liddicott]

Full system details at the end of this report

I have a section of a live wma8 stream which causes mencoder to get stuck 
at 100% cpu usage when converting to mpeg1video

I discovered this tracking down why http://www.byutv.org/byutv250.asx kept
hanging when playing to dxr3

I recorded to disk and extracted a sample bad clip 2MB using
mencoder -ovc copy -oac copy -endpos ......
this bad clip is available at http://www.liddicott.com/bad2.asf

If you try and convert to mpeg1 (as happens when playing to dxr3) with:
mencoder -ovc lavc -lavcopts vcodec=mpeg1video -o bb.avi bad2.asf

Then after a while it stops outputting and "top" shows 100% cpu on mencoder

It is worth noting that this wma8 stream is new-ish and has 0 length frames 
(mplayer was recently patched for this) and may well have other strange and
new things in it.
