Of course. Both of them (mplayer through SDL) use
"DecompressSequenceFrameS", a function found
in the QuickTime header ImageCompression.h.
Relevant source files are "SDL_QuartzYUV.m"
for SDL and "vout.m" for VLC (it's objective-C
code). Of course there's a lot of other functions
called :-)

Something like 10 or 15 years ago, (more likely
10 but it's less impressive to just say 10 :-)
when Apple first released QuickTime, they thought
that, somehow, decompressing and displaying still
pictures and movies *was* related. Many people,
including me, think that they were right, and still
are. For most people, the *point* of decompressing
an image is to *display* it. Transcoding isn't
the main use of media player and libraries, no
matter how many dvd get ripped.

Unlike your example, there *never* was 2 different
components that got "merged".
