Abstract
The primary goal for this project is to prepare the code base of x264 for encoding H.264 video with user defined sample depths. This will involve templating the encoder and migrating existing C code for use with higher sample depths.
A lot of optimizations are done with assembly, and will thus also need to be migrated. The secondary goal for this project is therefore to identify new assembly code to be written.
Milestones
| Status | Deadline | Description |
|---|---|---|
| Done | May 30 | 16-bit infrastructure ready for testing |
| No problems encountered so far | June 6 | Encoding with 16-bit infrastructure produce same results as 8-bit infrastructure. |
Timeline
This schedule is preliminary.
| Status | Date | Period | Description |
|---|---|---|---|
| In progress | May 17 - May 23 | Week 1 | Identify C code that should be templated. |
| In progress | May 24 - May 30 | Week 2 | Start templating the encoder for 16-bit infrastructure. |
| Not started | May 31 - June 6 | Week 3 | Test templated encoder. Identify C code that need modification to support higher sample depth. |
| Not started | June 7 - June 13 | Week 4 | Start modifying the encoder to support higher sample depth. |
| Not started | June 14 - June 20 | Week 5 | Continue work with encoder. |
| Not started | June 21 - June 27 | Week 6 | Continue work with encoder. |
| Not started | June 28 - July 4 | Vacation | |
| Not started | July 5 - July 11 | Vacation | |
| Not started | July 12 - July 18 | Week 7 | Test encoder with higher sample depths. |
| Not started | July 19 - July 25 | Week 8 | Fix issues encountered during testing. |
| Not started | July 26 - August 1 | Week 9 | Modify build chain to allow compilation for higher sample depth. Add options to set sample rate. |
| Not started | August 2 - August 8 | Week 10 | Identify assembly code that needs modification to support higher sample depth. |
Repository
How to test the current code:
$ git clone git://github.com/irock/x264-high-bit-encoding.git $ cd x264-high-bit-encoding $ git checkout high-bit-encoding $ ./configure --disable-asm --enable-16-bit $ make
