ACAP version 12.4 – May 6, 2025

Overview

The release contains:

• ACAP Native SDK 12.4.0
• ACAP Runtime 2.0.0 (Release notes)
• Docker ACAP 3.0.2 (Release notes)
• Docker Compose ACAP 3.0.2 (Release notes)

Code examples:

• Code examples ACAP Native SDK 12.4.0 (Release notes)
• Code examples ACAP Computer Vision Solution 12.4.0 (Release notes)

Device software:

• Minimum AXIS OS version: 12.4

New additions

• Manifest schema updates:
  • New version 1.7.4
    • Allow all characters except \n and \r in the vendor field.
• A table of supported operations for the ARTPEC-8 DLPU has been added to the Computer Vision documentation.
• The eap-install.sh script is now able to handle HTTPS-only Axis devices by skipping certificate verification, as detailed in Build, install, control documentation.

Changes

• The axoverlay example was updated with support for corridor format.
• The axis-model-zoo has been updated with clearer and up-to-date information regarding how the model results are obtained.

Bug fixes

• Architecture specific file and time handling.
  • In SDK versions 12.0-12.3, flags for file offset and time handling (_FILE_OFFSET_BITS,_TIME_BITS) weren't properly managed by the armv7hf (32-bit) SDK, this might cause undefined behavior when using data types like off_t, time_t, and file position functions.

Recommendation: We strongly recommend rebuilding all ACAP applications built with SDK 12.0-12.3, targeting armv7hf 32-bit hardware with SDK 12.4 for proper operation.
