sizes of the original and the subimage are same.
 2015-07-02 16:24:26 +03:00
Arttu Ylä-Outinen cec9b937dc Make image list resize use realloc.

 2015-07-02 16:14:51 +03:00
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.
 2015-07-02 16:10:51 +03:00
Ari Koivula df50a0dae6 Move config_parse into api. 2015-07-02 15:52:24 +03:00
Ari Koivula 4e5326d3d5 Move encoding to API. 
- Api->encoder_encode can now be called repeatedly to start encoder
  jobs and to retrieve the results.

 2015-07-02 15:52:23 +03:00
Ari Koivula 9a3edce3fc Separate input and output from encoding.

  output for encoding.

Conflicts:
	src/encmain.c
 2015-07-02 15:52:23 +03:00
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.
 2015-07-02 15:52:23 +03:00
Ari Koivula ad11d1bca5 Add kvazaar.h to hold high-level encoder API.

  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

were before rate control was implemented.
 2015-06-01 13:57:11 +03:00
Arttu Ylä-Outinen b0435d37a9 Update rate control parameters.

 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.

updated whenever a frame is written.
 2015-05-19 10:42:23 +03:00

Arttu Ylä-Outinen 815a2bea55 Use bitstream_tell to get stream position. 2015-05-15 13:57:50 +03:00
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 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 87936eb99f Revert "Fix keeping of reference frames over IDR boundary." 
This reverts commit b43f1cb9eb.

 2015-05-04 17:38:16 +03:00
Ari Koivula 9015aab996 Clean up IDR handling code. 
- IDR was called RADL, probably because the NAL type is IDR_W_RADL.
- Move things around to make it clearer what is happening.

  very short sequences.
 2015-04-16 17:30:36 +03:00
Ari Koivula 7028846423 Fix bug in intra mode search. 
- The cost of the first mode in the mode list was returned instead of cost of
  the selected mode, as this used to be the best mode when the list was

- This pretty much affects only --rd=1 in inter frames.
