vvdec-3.2.0

on GitHub

Backward compatible API changes:

• add vvdecSIMD_Extension enum values VVDEC_SIMD_NEON_RDM, VVDEC_SIMD_SVE, VVDEC_SIMD_SVE2, VVDEC_SIMD_SIMDE_ANY

Other changes:

• add ARM NEON, NEON-RDM, SVE and SVE2 implementations for most existing SIMD functions
• properly implement ARM CPU feature detection
• add fuzzing infrastructure using libfuzz (enabled by VVDEC_FUZZING_BUILD)
• fix some PVS-Studio warnings
• fix several cases of undefined behaviour (uninitialized memory, negative shifts, integer overflows)
• fix memory overflows triggered by broken bitstreams
• fix memory leaks when reading broken bitstreams
• add more bitstream conformance checks to detect invalid bitstreams
• use unaligned loads in x86 SIMD code where appropriate
• add build option VVDEC_WRITE_INPUT_BITSTREAM for debugging
• some general code cleanup

Known Issues:

• There are several open issues, which we assume to have fixed, but they are still open in OSS-Fuzz:
  • #356
  • #350
  • #349
  • #348
