MJPEG Tools Svn

Add y4munsharp filter. Based on the GIMP's unsharpmask plugin.

interlacing information now read from stream. If not specified in stream
and not on the commandline, bail out...

corrected runtime options and help message...

Ok, here we go... What has happened so far?

1. switched back to circular full-search (with early termination) as it
seems to be the only MC-algorithm suitable for deinterlacing. See the
source, if you want to know more about it...
2. Completely implemented Generalized Sampling Theorem (GST).
3. Implemented Scene-Change-Detection
4. Removed all ugly compiler-warnings
4b.removed (hopefully) all memory-leaks/memory-problems
5. "Soccer-Test": passed... :-)))
6. better than my Phi**** 100Hz TV-Set-deinterlacer...
7. I have forgotten, to ...

Still to be done:
-----------------

- Man-page/Dokumentation (I hate that...)
- Fix runtime options
- field-dominance detection

Have fun!

Ok, folks,... all I guess I can do any further on this thing is clean the
code from all those ugly warnings and leftovers...

Add a sanity check that if --cbr is used that a bitrate has been set either
by the selected format or by an explicit -b.

Oops - can't make the --cbr requiring a bitrate check here because the
-f option may set a rate later. Make the check in mpeg2encoptions.cc instead.

With --cbr a bitrate must be specified using -b (a Constant Bit Rate of 0 makes
no sense!).

Tidying up a bit.

Implement --cbr and fixed the --closed-gop option (it doesn't take an argument).
--cbr turns off -q (sets it to 0).
