+
+ This is a port of the Berkeley MPEG Video Software Decoder v2.0 to Linux.
+
+ Two binaries are provided. They require the ld.so shared library loader.
+
+ mpeg_play
+
+ A binary compiled from the stock sources, using the XFree86-2.0 libraries.
+ It was compiled with the flags: -O2 -fomit-frame-pointer -m486 (implicit)
+ using gcc 2.5.4, with some debugging code left out. Uses the X shared memory
+ extension that XFree86 v2.0 provides, which is a big win. The stock sources
+ compile cleanly and trivially.
+
+ mpeg_vga
+
+ A non-X version that uses svgalib. It is slightly faster than the X version
+ with shared memory and can use low resolution graphics modes. Also, with
+ truecolor graphics cards that svgalib supports (Cirrus, ET4000), full color
+ dithering can be used, which is very pretty. The graphics mode to be used can
+ be set with the GSVGAMODE environment variable. Requires svgalib 0.91 or
+ later installed.
+
+ For full color dithering (-dither color), 320x200x16M graphics mode is used
+ if it is available and the picture is small enough; if not, 640x480x16M is
+ used if available. 32K mode probed similarly.
+
+ For most other dithering methods, 320x200x256 standard VGA graphics mode is
+ used if the picture is small enough; 640x480x256 otherwise.
+
+ For mono dithering, 640x480x2 VGA graphics mode is used.
+
+ [NOTE: The previously uploaded version contained patches for some hacked
+ version of the stock sources; sorry for that.]
+ Patches for the stock sources are included (mpegvga.patch). It removes X
+ references, and uses svgalib instead. Also, the speed of gray dithering and
+ full-color dithering has been improved. svgalib v0.91 or later is required to
+ compile; it can be found on sunsite.unc.edu, directory /pub/Linux/libs.
+ [Speed hack have been incorporated into the main source]
+
+ mpeg_play -h (or any other invalid flag) displays dithering and other options.
+
+ Note that with gray dithering, very little time is spent converting from the
+ raw uncompressed data to a screen bitmap suitable for display, making it
+ significantly faster than the other methods.
+
+ The v2.0 source is available on sunsite.unc.edu. For sample MPEG data,
+ mm-ftp.cs.berkeley.edu, /pub/multimedia is one place to look.
