Ignore my previous working comment - it's failing with -lavdopts threads=4

Again it's OK with r36417.

I've uploaded my test (only 10 meg), others also fail.

On r36418 the issue is present, though it doesn't crash - just spews 
lots of the h264 errors renders the first frame and hangs <ctrl><c> needed.

On head I get this crash after it decides to quit -

there are so many errors as below my xterm scroll back is full - I 
assume you will be able to reproduce so haven't gone out of my way to 
get the start.

Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

FATAL: Could not initialize video filters (-vf) or video output (-vo).
