Harish Mahendrakar	0cc032d9ff	Clean up HBD support before split	2026-08-07 17:25:44 +00:00
Harish Mahendrakar	a30bb77acf	Fix hevc_dec_fuzzer to support High Bit Depth (HBD) allocations. ... The fuzzer previously allocated output buffers assuming 8-bit depth (1 byte per pixel) even when decoding HBD streams (10-bit), which use 2 bytes per pixel (stored as 16-bit). This led to heap-buffer-overflow during format conversion in ihevcd_fmt_conv. This fix: 1. Adds mBitDepth tracking to the Codec class in the fuzzer. 2. Updates allocFrame to scale buffer sizes by 2 if bit depth > 8. 3. Updates decodeHeader and decodeFrame to detect bit depth changes from dec_op.s_disp_frm_buf.u4_y_bit_depth and trigger reallocation when it changes, similar to resolution changes.

Vivek R Jadhav	1ff848b02a	hevc_dec_fuzzer: Fix output buffer allocation size calculation and add YUV444P as output format ... This prevents a heap buffer overflow write of size 1 during format conversion when decoding stream with odd dimensions.

Ananya Sharma	1e08a022f7	Fix CL for failing targets in git_main-throttled-haiku ... This change adds the 'no_bti' default to hevc_dec_fuzzer and hevc_enc_fuzzer as they statically link against libraries lacking BTI support. This is done to fix the linker errors raised in haiku_fuzz_shiba-trunk_staging-userdebug and haiku_fuzzcoverage_shiba-trunk_staging-userdebug targets.
