avi regression

I have an IP Camera from That camera generates an AVI on motion detection and uploads that video to my FTP server. can be used as an example of the error-proned video files.

I then attempt to turn that AVI into an MP4 and WEBM video later, but none of the files after the AVI like to run anywhere. VLC will play the AVI.

How to reproduce:

% ffmpeg -i 2015-09-14t12.47.26.avi -an -vcodec copy -movflags faststart output.mp4
% ffmpeg -i 2015-09-14t12.47.26.avi -c:v libvpx -minrate 1M -maxrate 1M -b:v 1M -an output.webm
