libvpx crash in RD code when starting second pass #79

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What is the expected behavior? What do you see instead?

ivfenc should finish the second pass successfully. It crashes early, though.

What version are you using? On what operating system?

v0.9.0-71-g3245d46
Ubuntu 10.04, x86_64

Can you reproduce using the ivfdec or ivfenc tools? What command line are
you using?

ivfenc --passes=2 stream.yuv stream.webm

stream.yuv is generated from 
http://downloads.paramount.com/mp/startrek/Trlr2_internet_480p.mov using 
mplayer -vo yuv4mpeg -ao null

Not every file triggers this bug, thus I propose using the publicly available 
test vector from Paramount.

Please provide any additional information below.
