animation fails to create a movie with 'ffmpeg_file' backend #2482
Description
I am having trouble saving my animations using ffmpeg 2.0.1
The temp files get created, but the call to ffmpeg fails with the following error:
Option vframes (set the number of video frames to record) cannot be applied to input file _tmp%07d.png -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.
Error parsing options for input file _tmp%07d.png.
Error opening input files: Invalid argument
I am assuming the way in which ffmpeg takes arguments has changed between versions?
