i basically agree.
and it is super simple.
it took me two days during(!) piksel (while drinking beer and stuff) to 
hear of gavl/gmerlin and implement support for it in Gem.

for me, gstreamer and gmerlin do not directly compete. while both claim 
to be "multimedia frameworks", the former is hard to interface on the 
data-level from a host application; however pipelines (within the 
gst-framework) are highly optimized and do not require much thinking of 
the host-programmes authors. otoh, gmerlin is a straighforward API to 
read data from a media-stream into your host application (writing is 
possible but more complicated)

and Gem :-)

gavl itself has been packaged into debian since etch.
unfrotunately gavl is just the interface that defines how frames of data 
look like, whereas the actual decoding library is in a a package called 
gmerlin_avdec, which is _not_ in proper debian.
however, it is available through debian-multimedia by christian marillat.
