MF_E_ITA_ERROR_PARSING_SAP_PARAMETERS
MF_E_ITA_ERROR_PARSING_SAP_PARAMETERS is specific to WMDRM Secure Audio Path policy data. The ITA reached the stage where it must interpret SAP parameters and rejected their representation or contents.
Preserve the protection data boundary
- Record which protected audio stream and requested action produced the error.
- Check custom source or DRM integration code that transports protection-system-specific data into the ITA.
- Compare the exact policy/header data path with a working protected audio asset from the same protection system.
Do not diagnose this as an ordinary audio media-type parsing problem. Sample rate, channel count, or AAC/MP3 codec negotiation happens in a different layer. The ITA translates native content policy into the common Media Foundation policy model, and protected audio outputs can be governed through trusted audio mechanisms such as PUMA. The most useful evidence is the original ITA HRESULT and the protection metadata path immediately before SAP parsing.
