- ######### PREREQUISITE
- In order to use this program, you need to have the program "mpeg_encode",
- available from Berkeley:
- http://bmrc.berkeley.edu/frame/research/mpeg/mpeg_encode.html
- or "ppmtompeg" from the netpbm package:
- http://netpbm.sourceforge.net
- Both source code and binaries for several platforms are available.
- ## old:
- After successful compilation, put the executable named "mpeg_encode" in
- a bin/ directory that any users of GRASS have in their path
- (I put it in /usr/local/bin or you could put it in $(GISBASE)/bin)
- If you intend to use ppmtompeg, make sure you make a soft link to it:
- ln -s /usr/bin/ppmtompeg /usr/local/bin/mpeg_encode
- ## /old
- ## new:
- Make sure the "mpeg_encode" or "ppmtompeg" binary executable is somewhere
- in the PATH.
- ## /new
- I have mpeg_encode version 1.3 and found one bug that you may need to fix (it's been
- reported, but probably not fixed in the current release yet):
- mpeg_encode version 1.3, file param.c, around line 770:
- } else {
- strcpy(inputFileEntries[numInputFileEntries]->left, input);
- inputFileEntries[numInputFileEntries]->glob = FALSE;
- inputFileEntries[numInputFileEntries]->numFiles = 1;
- /********* I added this line to FIX bug: ************/
- inputFileEntries[numInputFileEntries]->numPadding = 0;
- }

- ######### MPEG Players
- There are a couple of versions for X that I know of:
- The standard player -
- ftp://mm-ftp.cs.berkeley.edu/pub/multimedia/mpeg/play/
- Debian package (+source code):
- http://packages.debian.org/ucbmpeg-play
- An enhanced version of above with Motif playback controls:
- (ftp site no longer functional??)
- ftp ftp.geom.umn.edu
- /priv/daeron/bin/mpeg_play-arch.tar.Z (where arch = your machine architecture)
- There are also Public Domain or shareware players available
- for Windows and MacIntosh at various sites on the internet.
- ######################
- ######### THIS VERSION:
- Added the -c option for "on the fly" conversion (using prerequisite
- r.out.ppm with stdout option, available on moon.cecer.army.mil). This
- saves disk space, but can only be used when there is a single viewframe.
- Use of this option will also override any size specification, producing
- an MPEG with the dimensions of the CURRENTLY DEFINED GRASS REGION. So
- set your region carefully before using this option.
