EXAMPLES:
1. to decode a bitstream with double precision IDCT, such as
to create a reference reconstruction set of frames:
mpeg2decode -r -f -o0 rec%d -b bitstream.mpg
2. to decode a bitstream with fast integer IDCT, such as
to create a test reconstruction set of frames:
mpeg2decode -f -o0 rec%d -b bitstream.mpg
3. To substitute reference pictures with external reference
pictures (ref%d):
mpeg2decode -f -x ref%d -b bitstream.mpg -o0 rec%d
4. Same as 3. only using a single large concatenated file for the
sequence of reconstruction frames.
mpeg2decode -f -g -x ref%d bitstream.mpg -o0 rec%d
5. Decode an SNR enhancement bitstream at the same time as base layer
stream:
mpeg2decode -o0 rec%d -e snr_bitstream.mpg -b base_bitstream.mpg
6. Decode a Spatially scalable bitstream
Step 1: create lower layer reconstruction
mpeg2decode -f -o0 llrec%d -b base_layer.mpg
Step 2: decode enhancement bitstream, combined reconstruction.
mpeg2decode -f -l llrec%d -b enhancement_layer.mpg -o0 rec%d
------------
where:
-o0 specifies .Y, .U, .V input
-f specifies field interleaved format
-b is the bitstream flag
-g specifies substitute file is a large concatendated one.
-e substitution flag
ref.pic filename of substitution sequence
bitstream.mpg bitstream
test%d output file pattern
