| 1624 | giacomo | 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 |
||
| 38 | |||
| 39 | ------------ |
||
| 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 |
||
