[Bug 386397] [NEW] ffmpeg gets "Illegal instruction" on Pentium II

[Josh]

Public bug reported:

Binary package hint: ffmpeg

Tried to create a video out of jpeg frames. Used this command: `ffmpeg
-i r%05d.jpg tl.avi`

Came back with this:

Illegal instruction


Using Ubuntu 9.04. ffmpeg package is 3:0.svn20090303-1ubuntu6.

problem.
