Arttu Ylä-Outinen 4a7b86a43b Make g_exp_table statically allocated.
Removes the need to free the table.

Arttu Ylä-Outinen b130ecc9bb Fix "reference not found" when GOP is enabled.
The encoder state must be cleared by calling encoder_next_frame before
calling read_one_frame.

Ari Koivula 7e98a483d7 Use the API for checking whether the encoding is finished. 2015-07-02 16:14:51 +03:00
Ari Koivula fc58748ae8 Output bitstream through API.
- Use the existing bitstream_t type to give access to the bitstream.
  We can extend it later to make it a linked list like I was planning
  to do with the payload type.
- The main encoder now also stores the bitstream in memory.

Ari Koivula df50a0dae6 Move config_parse into api. 2015-07-02 15:52:24 +03:00
Ari Koivula 4e5326d3d5 Move encoding to API.

Ari Koivula 9a3edce3fc Separate input and output from encoding.
- Move image_t and pixel_t to the kvazaar.h API.

  output for encoding.

Ari Koivula f87cea78da Wait for bitstream immediately after encoding the frame.
- This should reduce the encoding delay by one frame when encoding in
  real time.

Ari Koivula ad11d1bca5 Add kvazaar.h to hold high-level encoder API.
- Move encoder initialization from main to kvazaar.c.
- Have main use the API for initialization.

Ari Koivula 5c28745457 Move OWF logic and CLI stuff out of encoder_compute_stats.
- CLI stuff is moved to either cli-module or to main function.
- OWF stuff is made more explicit by counting the frames instead of
  communicating through encoder_state_t.stats_done.
2015-07-02 15:45:33 +03:00
Ari Koivula ea50d03e52 Add cli module and move interface stuff to there. 2015-07-02 15:45:33 +03:00

Arttu Ylä-Outinen 984e7cb4e0 Fix setting QP when rate control is disabled.
When rate control is disabled, QP and lambda are now selected like they
were before rate control was implemented.
2015-06-01 13:57:11 +03:00
Arttu Ylä-Outinen b0435d37a9 Update rate control parameters.
On each frame, adjust the parameters alpha and beta in the equation

    lambda = alpha * pow(R, beta)
2015-05-29 11:50:08 +03:00
Arttu Ylä-Outinen b24d92bd6e Move initialization of constants to encoder.c.
Some constants used in rate control are now initialized only once instead
of being computed on every frame. Adds pixels_per_pic, target_avg_bppic,
target_avg_bpp and gop_layer_weights to encoder_control_t.
2015-05-29 11:45:36 +03:00
Arttu Ylä-Outinen b54d5aa91f Select GOP picture weights according to bitrate.
Pictures in same layer have equal weights. At low bitrates, the difference
between low and high layers is greater than at high bitrates.
2015-05-29 11:43:42 +03:00
Arttu Ylä-Outinen 93d2a95ddc Implement rate control in lambda domain.
- Rate control adjusts the lambda value.

Ari Koivula 56bb8e75ba Fix non-deterministic behavior with tiles.
- Depend on the whole previous frame.
- We should really go through all these FIXME's sometime.
2015-05-12 12:00:32 +03:00
Ari Koivula dd11dd488b Modify Valgrind tests for GOP.
- Add --owf=0 test.
- Allow GOP tests to fail, as they are still experimental.
- Reduce the number of frames to 20.
2015-05-11 13:35:16 +03:00
Ari Koivula a48d91dacd Fix WPP not working when SAO is off and OWF is on.
- Every wavefront row was being set to done when the first wavefront
  row got done.
- Looks like I didn't understand how the data structure worked when I
  "cleaned this up", and it didn't get caught in tests because it
  needs OWF to be on to affect anything.
2015-05-11 12:01:17 +03:00
Ari Koivula 00ec1f16c5 Move Travis-ci stuff to scripts and add more tests.
- Make valgrind tests run in parallel.
- Install only the tools necessary to run each test.
- Make individual tests smaller and faster, but run more tests
  with a more diverse set of parameters.

  fix will work but I think it looks better.
