[FFmpeg-devel] [PATCH] Remove extensions from MPEG-PS muxers.

[Reimar Döffinger]

When the file-name is .mpg, most users will not want a
"MPEG-1 Systems" that almost all programs will fail to play (at least
as soon as e.g. AC3 is muxed into it).
It is also likely that a user encoding to a file ending in .vob
is trying to encode in a DVD-compatible format.
Either way, since two formats have the same extension, it would
be "random" what the user gets, which certainly is not a good
thing either.

Related to trac issue #1720.
