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.
- QP is selected according to lambda.
- Bits are allocated for GOPs and individual pictures.
 2015-05-19 11:40:51 +03:00
Arttu Ylä-Outinen 664de9ade0 Keep track of bits written in current gop. 
Adds cur_gop_bits_coded into encoder_state_config_global_t. The count is
updated whenever a frame is written.
 2015-05-19 10:42:23 +03:00
Arttu Ylä-Outinen 4a5698a6ba Implement basic rate control. 2015-05-19 10:42:17 +03:00
Arttu Ylä-Outinen d27cde55a4 Add --input-fps and --bitrate parameters. 2015-05-15 13:57:51 +03:00
Arttu Ylä-Outinen 5b8cd76f01 Keep track of total number of bits coded. 
Adds total_bits_coded into encoder_state_config_global_t. The count is
updated whenever a frame is written.
 2015-05-15 13:57:50 +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 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.
 2015-05-05 17:17:32 +03:00
Ari Koivula 87936eb99f Revert "Fix keeping of reference frames over IDR boundary." 
This reverts commit b43f1cb9eb.

- This change resulted in use of uninitialized memory with owf != 0.

Ari Koivula ed670f4185 Fix coverity warning.

  could be called with depth == 4.
 2015-05-05 11:54:09 +03:00
Ari Koivula 2276e0028f Fix coverity warning. 
- False positive about use of an uninitialized value. Actually just
  copying uninitialized data from one struct to another.

 2015-05-05 10:23:52 +03:00
Ari Koivula 80cbda364b Fix coverity warning.

  dead code now instead.
 2015-05-05 10:17:06 +03:00
Ari Koivula 08d079773f Fix coverity warning. 
- Dead code.
 2015-05-05 10:12:01 +03:00
Ari Koivula e225c5b302 Fix coverity warning. 
- Dead code due to current value of MRG_MAX_NUM_CANDS. Not sure if this
  fix will work but I think it looks better.
 2015-05-05 10:06:18 +03:00

 2015-05-04 17:38:16 +03:00
Ari Koivula 1c3873f5b2 Fix coverity warning. 
- Overflow from buggy implementation of modulo behavior for
  pattern_type. As there is no need for such behavior I removed it.
 2015-05-04 17:38:16 +03:00
Ari Koivula 6234b09461 Fix coverity warning. 
- A false alarm about buffer overflow. No new modes are added if all modes
  are already in the list.
- Skip checking predicted modes if all modes are in the list.

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.

Ari Koivula c0c9bc619a Fix valgrind warning. 
- Attribute state->global->slicetype was used before being initialized.
- The reference frame lists should be updated based on current frame,
  not on previous frame (or uninitialized data).

Ari Koivula 13924a2057 Add --no-info parameter. 
- Stops encoder information from being added to bitstream.
- The version information overhead is too big when doing comparisons with
  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
  sorted. Should only matter when doing inter coding.
- This pretty much affects only --rd=1 in inter frames.
