Fix DRM HAL: YAML structure, AIDL compilation errors, CMake build, and doc typos by outdooruseonly · Pull Request #401 · rdkcentral/rdk-halif-aidl

outdooruseonly · 2026-04-08T13:14:30Z

Multiple correctness issues across the DRM HAL and related modules — broken YAML, AIDL files that fail to compile, a missing CMake override, and doc/API inconsistencies.

`drm/current/hfp-drm.yaml`

supportedHdcpLevels wrongly indented as child of supportedSecurityLevels list items → moved to sibling under drm:
Typo: toptal → total

`drm/current/CMakeLists.txt`

Added missing AIDL_BIN override block (present in all other modules); without it, custom AIDL_BIN paths are silently ignored

`drm/current/com/rdk/hal/drm/DecryptArgs.aidl`

Removed invalid in direction specifiers from parcelable fields — only valid on method parameters

`drm/current/com/rdk/hal/drm/ICryptoPlugin.aidl`

Removed unused DestinationBuffer and SharedBuffer imports (AIDL compilation failure)
@param[in] width/height — fixed possessive typo and switched to @param[in] style; mediadrm → MediaDrm

`drm/current/com/rdk/hal/drm/IDrmFactory.aidl`

Removed unused SecurityLevel import
getSupportedCryptoSchemes() doc: createPlugin → createDrmPlugin() / createCryptoPlugin()

`drm/current/com/rdk/hal/drm/IDrmPlugin.aidl`

Removed unused IDrmPluginListener and KeyStatus imports
"property value bye array" → "property value byte array"
Parameter rename: wrappedkey → wrappedKey
@param level → @param securityLevel in openSession() doc
IDrmFactory::createPlugin → IDrmFactory::createDrmPlugin() in interface description
closeSession(): replaced @return (implicit) status-code wording with @exception semantics
Removed stray trailing backticks in setCipherAlgorithm() and setMacAlgorithm() doc blocks

`drm/current/com/rdk/hal/drm/Pattern.aidl`

Typo: mNumBytesOfEncryptedDatad → mNumBytesOfEncryptedData; rewrote sentence to remove the undefined field reference

`avbuffer/current/com/rdk/hal/avbuffer/IAVBuffer.aidl`

EX_ILLEGAL_STATUS → EX_ILLEGAL_STATE (invalid Binder exception name)
"has not be configured" → "has not been configured"; 'secureHeap' → `secureHeap`
@exception EX_ILLEGAL_STATE — added missing condition and punctuation

`videodecoder/current/com/rdk/hal/videodecoder/IVideoDecoder.aidl`

@param[in] maxWidth copy/paste described "maximum height" — corrected
open() / openWithResolution(): single-quoted identifiers → backticks; "The decode" → "The decoder"; trailing whitespace removed

- Introduced IDrmControllerListener, IDrmEventListener, and IDrmManager AIDL interfaces for DRM controller callbacks and resource management. - Added KeySetId, KeyValue, NumberOfSessions, ProvideProvisionResponseResult, ProvisionRequest, and SecurityLevel parcelable data structures for handling DRM-related data. - Defined Status enum for error handling in DRM operations, covering various error scenarios. - Created hfp-drm.yaml file to outline the HAL feature profile for DRM, including a placeholder for supported features.

…RM and Crypto plugin definitions

…sing headers.

… decryption.

Added a TODO for crediting Android with the DRM design.

…ol creation. Extended videoDecode::openWithResolution to specify a maximum resolution that is less than that specified in codecCapabilities.

Pull request overview

This PR introduces a new DRM HAL interface set (modelled after Android 16’s Drm/Crypto plugin architecture) and adds corresponding documentation and MkDocs navigation, while also deprecating the existing CDM docs. It also adds a new openWithResolution() overload to the video decoder API and updates AVBuffer documentation for secure-pool preconditions.

Changes:

Add a new drm/current AIDL interface set plus HFP and module CMake configuration.
Add DRM HAL documentation and link it into MkDocs navigation; mark CDM docs as deprecated.
Extend IVideoDecoder with openWithResolution(); update IAVBuffer docs around secure pool creation constraints.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

https://api.github.com/graphql
- Triggering command: `/usr/bin/gh gh issue create --repo rdkcentral/rdk-halif-aidl --title IAVBuffer.aidl: createVideoPool() doc uses wrong parameter name 'videoDecoderIndex' instead of 'videoDecoderId' --body ## Description

In avbuffer/current/com/rdk/hal/avbuffer/IAVBuffer.aidl, the createVideoPool() doc comment references the parameter as videoDecoderIndex in both the @param tag and the @exception condition, but the actual method signature uses v (http block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled
