Comment (by w3sip):

 1) Regarding reproducing the demux issue: too much code to show it here.
 I'll submit the patch on the mailing list.
 2) Regarding the decoding of the attached frame: I'm attaching a package
 that can reproduce the issue on trunk, 2.8, 2.7.2, using the following
 - use buildFFMPEGMac.sh to build ffmpeg (as attached it builds master)
 - use Makefile to build test.cpp
 - run 'test x.jpg'

 I'm seeing the following output with the above three versions:

 Starting up
 [mjpeg @ 0x1004800] No JPEG data found in image
 Decode result: -1094995529
