seek-h262 software is a portable MPEG decoder.
Portability
The decoder itself (as found in the `262′ subdirectory of this ditribution)
should be fairly portable. Some assumptions are made though:
· an ANSI compliant compiler is available
· the endianness is either big, either little
· “char” is 8 bits, “short” is 16, “int” 32 and “long” is 32 or 64
· right shift is signed
The test programs (those sources in `src’ subdirectory) require more than the above to compile.
Usage: h262 [OPTIONS] FILE
Decode system or video streams in FILE(s).
Options:
-B, –skip-bidirectionally-predictive-coded
skip bidirectionally predictive coded pictures
-I, –idct dummy|mpeg3video_idct_conversion
select inverse dct routine
-P, –skip-predictive-coded skip predictive coded pictures (implies -B)
-b, –Berkeley-fuck-up fuck predictions the Berkeley way
-c, –color-space GRAYSCALE|YCbCr|none
set output color space (YCbCr by default)
-p, –ppm=PREFIX ?
-s, –streams STREAMS specify the video streams that are to be
decoded (e0 most of the times)
-t, –timing output decoding time
-v, –verbose output decoding progress
–help display this help and exit
–version output version information and exit
What’s New in This Release:
· The interface was modified slightly to allow for better data alignment, and thus for better SIMD support.
· Other changes include minor documentation updates, portability fixes, and minor interface additions.
