Harish Mahendrakar	18fc8f6b52	Added support for 420 10-bit decoding. ... This is the initial version and doesn't enable SIMD functions yet. Has not been tested extensively yet. This is not ready to be merged into main branch yet.	2026-08-07 03:21:32 +00:00

Sushant	b9239efd75	hevcdec: Add assemblies and intrinsics for intra prediction ... TODO: SIMD acceleration - chroma intra prediction modules for trans size 32 - chroma itrans recon for trans size 32 - all methods of ihevc_itrans_res.c - ihevc_chroma_recon_nxn_ccp - for neon, chroma padding needs fixing. The function assumes pad width 80 always which does not hold for 444 chroma format idc. for 444, pad width is 160. - ihevc_inter_pred_luma_horz_w16out_a9q causing bus error. This is seen when building with cmake on local setup and for arch 32. On Aosp tree this issue is not seen. - format conversion routines added for 422 and 444 - implicit rdpcm allows disabling of filters for intra pred modes 10 and 26. The C functions are updated to support this. simd functions requires updating. TODO: au1_ref_sub_out array is on stack and this increased irrespective of chroma format idc. Should this allocation make use of color format to reduce stack size TODO: check compliance for different sps range extension fields TODO: enable deblocking support TODO: enable sao support TODO: enable slice and tile support TODO: enable other 444 specific tool sets TODO: add support for 422 for inter slices Test: ./hevcdec Change-Id: I013e44e024258f2f84690fdc0109200109052036	2026-08-05 14:37:42 +00:00

Vivek R Jadhav	938dbd274d	libhevcdec: Fix chroma padding in ARM and ARM64 NEON assembly to support 160-byte width ... For the 444 chroma format, the chroma pad width is 160 bytes. However, the ARM and ARM64 NEON chroma padding assembly functions previously assumed a hardcoded pad size of 80 bytes (writing exactly 5 stores of 16 bytes), leaving the rest of the padding region uninitialized.

Harish Mahendrakar	b8c9100658	Remove incorrect prefix from ihevcd_itrans_res_dc ... ihevcd_itrans_res_dc is defined in common folder but has a wrong prefix of ihevcd_. This is now fixed to ihevc_.	2026-07-29 17:08:35 -07:00
Harish Mahendrakar	2358e96df3	Add few function selectors in common for modules defined in common. ... This is needed to ensure that the tests in tests/common do not depend on headers from decoder folder. Decoder still has its own function selectors and those will be updated in subsequent commits to use these common selectors to avoid code duplication.	2026-07-29 16:29:43 -07:00

Harish Mahendrakar	8dffbdd2d0	Move IVD_ARCH_T and IVD_SOC_T to iv.h and rename as IV_ARCH_T and IV_SOC_T ... This helps in decoupling unit tests in common from depending on ivd.h	2026-07-29 15:37:52 -07:00
Sushant	281bad69de	hevcdec: undo changes made for chroma intra pred lut ... changes were made to chroma intra pred look up tables in the context frext profile support. The corresponding assembly changes were not yet merged but the tables are. The table changes are now reverted keeping lut and assemblies in sync. This reverts commit f990e295bd.

Sushant	646ee99888	libhevc: Direct memcpy and memset calls to enable _FORTIFY_SOURCE ... Bypass wrappers functions for memcpy and memset, calling standard C library functions directly.

Sushant	343fd870f9	hevcdec: Update cabac context tables of cbcr_cbf trafo depth 4 ... When decoding YUV444 streams with QuadtreeTUMaxDepthIntra set to 5, the chroma transform split depth can reach 4, since chroma TUs split down to 4x4, matching luma. During parsing of cbf_cb and cbf_cr, the context index is derived as IHEVC_CAB_CBCR_IDX + trafo_depth. Since YUV420 limits max chroma trafo_depth to 3 (min chroma TU size 8x8), only 4 contexts were allocated for IHEVC_CAB_CBCR_IDX (offsets 0-3). When trafo_depth reaches 4, this caused an OOB access into the neighboring IHEVC_CAB_TFM_SKIP0 context, corrupting CABAC state. This change resolves the OOB access by: 1. Increasing the size of IHEVC_CAB_CBCR_IDX from 4 to 5 in the enum, so that IHEVC_CAB_TFM_SKIP0 starts at IHEVC_CAB_CBCR_IDX + 5. 2. Inserting the 5th init context value (initValue = 1) at index 40 of each QP row in gau1_ihevc_cab_ctxts, across all 156 QP tables, as per the HEVC spec (ITU-T H.265 section 9.3.2.2).

Ram Mohan M	ad0a6d8688	hevcdec: add itrans residue functions ... These functions are similar to ihevc_itrans_recon_* with the exception that instead of computing recon directly they store residue to the destination buffer. This helps with additional transformation of the residue coefficients (rotation, rdpcm, ccp) before adding to the prediction data to generate the final recon.
