Joose Sainio 042b5078d8 [jccr] WIP initial implementation
Add somekind of search for joint chroma residual coding.
Bitstream is currently correct but prediction is incorrect because the jccr
is actually not used in the search.

Hard coded to be enabled

Arttu Makinen c5570abe1b Removed 'emt' variable from cu_info_t and changed 'emt' globally to 'mts' for consistency. 2021-02-10 12:08:05 +02:00
Arttu Makinen 2e7c342645 Implemented DCT2, DST7, and DCT8 transforms, and search for selecting transform for MTS. Using MTS results mismatch for luma component. 2021-02-02 11:09:43 +02:00
Arttu Makinen b9c3336f0e MTS bitstream encoding added for intra. Work with depths 0-3. 2021-01-18 20:44:36 +02:00
Sami Ahovainio 4768ba0628 Minor fixes to header writing. Added contexts for multi_ref_line and BDPCM. Functions added for writing both in bitstream, but they are both disabled for now. 2019-05-29 13:00:19 +03:00
Sami Ahovainio 5b46fbd878 Added multi_ref_idx variable for intra coding (is 0 throughout the code for now). Modified prediction flag writing. Chroma pred flag remains unchanged (ToDo). Added bitstream debug printing on VERBOSE mode. 2019-05-21 12:28:05 +03:00
Marko Viitanen ad310c77d3 Added EMT transforms to the strategies 2018-10-17 08:56:49 +03:00
Arttu Ylä-Outinen fb462b25ef Fix transform skip for inter
The transform skip flag in cu_info_t was stored under the intra
substruct even though transform skip can be used for inter as well. This
caused bitstream errors. Fixed by moving the flag out of the substruct.

Arttu Ylä-Outinen ecb0275cdd Store CU arrays as pointers to the main array
Changes field state->tile->frame->cu_array->data to point to the CU
array in the main encoder state. Removes the need to copy the CU array
to the main CU array after search.

Arttu Ylä-Outinen 24b462f801 Align coefficients to 8 bytes
Adds alignment attribute to lcu_coeff_t. The coefficients are sometimes
handled as 64-bit integers containing four coefficients so the arrays
should be aligned to 8 bytes.

Fixes a UBSan error about misaligned reads.
