Description

The attached image makes jifmux barf with the following pipeline:

GST_DEBUG='*:2' gst-launch-1.0 filesrc num-buffers=1 blocksize=4299656 location=1462395350.jpg ! 'image/jpeg' ! jifmux ! filesink location=foo.jpg
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

It seems EOI marker is not present within the last 5 bytes thus jifmux fails to find it.
