Bug#667504: libav-tools: bus error on sparc encoding vp8

[Jack Hill]

Package: libav-tools
Version: 4:0.8.1-1
Severity: normal

Dear Maintainer,

Using the avconv executable to encode a video with the vp8 codec (via libvpx) fails with a bus error. This happens with both webm and mkv containers.
The error does not happen if a different codec is chosen (e.g. libtheora).

To reproduce:
0) get a video encoded in something other than vp8 (I used youtube-dl to get an h.264 encoded video).
1) try to transcode it with
avconv -i infile.mp4 outfile.webm
(avconv automatically chooses libvpx for a .webm file)
2) observe failure.

I will appily provide more debuggin information if provided with instructions for obtaining.
