And he doesn't remember how he decided what name to give the version he
released?

Better idea: try reading the version name. '0.4.9pre1' is an actual
released FFmpeg version; it corresponds, according to the Changelog and
'svn annotate', to revision 3298. 4752 is after that, so I would think
it very likely that it is the revision from which this was built.
(Although, given that the source was modified to change the version
number, there is no absolute guarantee that other changes were not made
at the same time.)

(As a side note: this is really a user question, not a development
question, unless the reason you want the source for the earlier version
is e.g. to figure out how to adapt the latest version to do something
which FFmpeg once did but has stopped doing. As such, it belongs on the
-user list.)
