Oh forgot, maybe this should be done to a52dec also?

Hi Matt,
I was wondering if you think it's possible to rename mpeg2dec
(partially) to libmpeg2. Lemme first explain the why, and then the how
(as I imagine it) :-)
Why
---
* The project is called libmpeg2.
* Their central product is libmpeg2, mpeg2dec is "just" a decoder
built on this and provided as a bonus.
* Debian calls it that way, too
* When stuff is based on libmpeg2, then their websites/docs will tell
the user to install "libmpeg2" to get mpeg2 support; it's pretty tough
for the user to find out that in order to get libmpeg2, they have to
install mpeg2dec-dev and mpeg2dec-shlibs ...
* Doing a rename now would still be relatively easy, since little
depends on it. The longer one waits, the more troublesome it becomes.
How
---
A simple way would be to just change the -dev and -shlibs splitoff to
provide libmpeg2(-dev) and libmpeg2-shlibs. But that doesn't scale to
well, should we require versioning the lib in the future.
Rather, I'd consider really renaming the package, or at least the
splitoffs; that is, you could still call the main pkg mpeg2dec, but
just rename the splitoffs.
Of course, that has to be done properly in order to avoid transition
problem. First off, the only package which depends on mpeg2dec is
gst-plugins. Changing that to depend on "mpeg2dec | libmpegs2" etc.
would be a trivial thing.
Then, the new libmpeg2(-dev)/libmpeg2-shlibs would replace (and
possibly conflict, needs testing) the old mpeg2dec-dev/mpeg2-shlibs
splitoffs.
The main potential update problem I see are people who installed
mpeg2dec & mpeg2dec-shlibs. When such a user then tries to do a "fink
install libmpeg2", that would fail due to package conflicts (unless
some nice improvements took place while I was gone :-). But getting an
update of "mpeg2dec" or an update-all working could be done by
changing the dependencies of mpeg2dec (the new one) to:
Depends: mpeg2dec-shlibs (= 0.4.0b-3) | libmpeg2-shlibs (= %v-%r),
...
I.e. the new mpeg2dec would work with both the old mpeg2dec-shlibs and
the new libmpeg2-shlibs
Cheers,
Max
