What's New

ID Summary
TIOVX-736 TIOVX shall support variable scale ratios for vxGaussianPyramidNode
TIOVX-1406 Create "tivx_utils_compare_refs_from_ipc_xfer" API for comparing handles sent acros processes

Upgrade and Compatibility Information

File Change description User application change required User application recompile required
include\TI\tivx.h When using the tivxReferenceExportHandle and tivxReferenceImportHandle API's with the image objects, the returned handles originally treated each plane separately, but now only uses a single pointer along with the size for all planes. This is aligns with how the framework allocates memory for multi-plane images. Please reference the API docs for more information. YES YES
include\TI\tivx_mem.h The return type of the tivxMemFree API has been changed from "void" to "vx_status" YES YES
include\TI\tivx.h The tivxGraphParameterEnqueueReadyRef API has been deprecated in favor of the standard vxGraphParameterEnqueueReadyRef API YES YES

Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit Meaning Description
1 (M=Major) Major revision Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor) Minor revision Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch) Patch number Incremented for all other source code changes. This include any packaging support code.
4 (b=build) Build number Incremented for each release delivery to CM. Reset for any change to M, m or p
