| 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 |
| |
