The problem is the length could not be computed correctly (we ask
libavformat for it).

When libavformat says the duration is undefined, the MLT avformat
producer rather assumes it is a live source and sets the producer to
the max duration MLT supports (INT_MAX) and with looping behavior.
ffprobe says the duration is zero, and ffplay plays it for a long time
(I did not wait). Adding acodec=aac to the first melt command resolves
it (it was defaulting to libvorbis).Curiously, webm output gives the
same problem, so it seems to be related to the usage of libvorbis in
the output. Using the ffmpeg utility to transcode a blipflash to mkv
or webm works fine. So, it is something in the API usage of the
avformat consumer on FFmpeg later than v1.2.
