NS_E_TRANSFORM_PLUGIN_INVALID

NS_E_TRANSFORM_PLUGIN_INVALID: an encoder transform plug-in was activated but failed the required interface or validation contract

NS_E_TRANSFORM_PLUGIN_INVALID (0xC00D1BE6) identifies a specific Windows Media/platform boundary: an encoder transform plug-in was activated but failed the required interface or validation contract. Keep this stage visible instead of collapsing it into a generic playback, network, or configuration failure.

Evidence to preserve

Record transform CLSID, binary version/bitness, requested interfaces, media types, and whether validation failed at activation or format negotiation.

Controlled verification

Use a transform built for the host architecture and expected interface set, then repeat the same transform insertion with unchanged media types.
