MJPEG Tools Svn

Use both the mjpegtools version number and mplex's version number.

Two different version numbers were printed depending how the program was invoked. Rather than have version numbers go backwards (from 2.2.2 to 1.6.x) the
MPLEX_VER macro was used in both places (previously MPLEX_VER was used in one
place and VERSION in the other). MPLEX_VER was incremented to 2.2.3 (to identify it as being newer than 2.2.2) and the MPELX_DATE changed to the GMT time of the version change.

-X, -q were in short_options but there was no code to handle them and they were
not in the long options. '-e' and '-m' were cruft, not used/obsolete and again
were in the short options but not the long options.

restored COMPILE variable required to enable ALTIVEC_CFLAGS

use getopt_long instead of getlong. wow.

Use HAVE_GETOPT_LONG instead of HAVE_GETLON

General build fixes and preparing for a new release candidate.
* remove .cvsignore from Makefile.am. .cvsignore is a CVS-file, which has no
function whatsoever in a release tarball. So it doesn't need an entry.
* start using noinst_HEADERS and include_HEADERS instead of adding headers
to the appname_SOURCES. We need to be careful with the headers that we
install, and we need to be clear about source requirements for each of
the binaries.
* Add installable include headers for libmpeg2encpp.so. Andrew, please double
check, I simply picked all the ones included in mpeg2enc.cc plus the ones
needed by them.
* Remove all CPU optimization/acceleration code from libmjpegutils.a and put
it in a separate non-installed lib (libcpuaccel.a).
* Prepare all stuff for using libtool. This makes the build easier. However,
it doesn't work yet because it tries gcc instead of nasm on .s sources.
GStreamer doesn't have this, so I need to double check this.
* RPM building is broken. See bug #88417 in RedHat bugzilla.
* Some more...
* Make distcheck now works.

Now using correct *decode* frame rate for calculating the
H:M:S:F timestamp labels on GOPs.

Added new framework for special-purpose syntax constraints for working
around oddities in particular players.
Tidied up header generation so it is all in one place.

Introduce stripe parallelism to make it easier to split encoding phases / backup
in encoding.
Add buffer of output with support for backing up
