| 2 | This a tool that either: |
|---|
| 3 | |
|---|
| 4 | 1. Extracts an independent non-base layer from a multi-layer bitstream, converts it to a base-layer bistream and writes it to a file. The extraction processs is defined in chapter F.10.2 of the HEVC version 2 specification. |
|---|
| 5 | |
|---|
| 6 | or |
|---|
| 7 | |
|---|
| 8 | 2. Extracts an additional layer set sub-bitstream from multi-layer bitstream and writes it to a file. The extraction processs is defined in chapter F.10.3 of the HEVC version 2 specification. |
|---|
| 9 | |
|---|
| 10 | |
|---|
| 11 | The tool is invoked as follows: |
|---|
| 12 | |
|---|
| 13 | ExtractAddLS <infile> <outfile> <Max temporal ID> <layer IDs of the extracted layers> |
|---|
| 14 | |
|---|
| 15 | The process that is invoked is decided based on the number of IDs that are given in the layer ID list. If only one layer ID is given, independent non-base layer rewriting process is invoked. If more than one layer ID is given, sub-bitstream extraction for additional layer sets is invoked. |
|---|
| 16 | |
|---|
| 17 | The result of independent non-base layer rewriting process can be decoded with an HEVC/H.265 v1 compliant decoder as long as the extracted independent layer conform with v1 specification text. The tool removes VPS from the output bitstream during rewriting so an HEVC/H.265 decoder should not expect it to be present. |
