1 EXAMPLES:
2
3 1. to decode a bitstream with double precision IDCT, such as
4 to create a reference reconstruction set of frames:
5
6 mpeg2decode -r -f -o0 rec%d -b bitstream.mpg
7
8 2. to decode a bitstream with fast integer IDCT, such as
9 to create a test reconstruction set of frames:
10
11 mpeg2decode -f -o0 rec%d -b bitstream.mpg
12
13 3. To substitute reference pictures with external reference
14 pictures (ref%d):
15
16 mpeg2decode -f -x ref%d -b bitstream.mpg -o0 rec%d
17
18
19 4. Same as 3. only using a single large concatenated file for the
20 sequence of reconstruction frames.
21
22 mpeg2decode -f -g -x ref%d bitstream.mpg -o0 rec%d
23
24 5. Decode an SNR enhancement bitstream at the same time as base layer
25 stream:
26
27 mpeg2decode -o0 rec%d -e snr_bitstream.mpg -b base_bitstream.mpg
28
29 6. Decode a Spatially scalable bitstream
30
31 Step 1: create lower layer reconstruction
32
33 mpeg2decode -f -o0 llrec%d -b base_layer.mpg
34
35 Step 2: decode enhancement bitstream, combined reconstruction.
36
37 mpeg2decode -f -l llrec%d -b enhancement_layer.mpg -o0 rec%d

40 where:
41 -o0 specifies .Y, .U, .V input
42 -f specifies field interleaved format
43 -b is the bitstream flag
44 -g specifies substitute file is a large concatendated one.
45 -e substitution flag
46 ref.pic filename of substitution sequence
47 bitstream.mpg bitstream
48 test%d output file pattern
