What does HRESULT 0xC00D1BE7 (NS_E_EDL_REQUIRED_FOR_DEVICE_MULTIPASS) mean?

NS_E_EDL_REQUIRED_FOR_DEVICE_MULTIPASS

NS_E_EDL_REQUIRED_FOR_DEVICE_MULTIPASS: the failing boundary

NS_E_EDL_REQUIRED_FOR_DEVICE_MULTIPASS (0xC00D1BE7) means To use two-pass encoding, you must enable device control and setup an edit decision list (EDL) that has at least one entry. The important boundary is device multipass prerequisites; do not replace this result with a broader “Windows Media failed” diagnosis.

What this result proves

This code proves that two-pass device encoding requires device control plus a non-empty edit decision list. It does not, by itself, prove a codec, permissions, network, device, or media problem outside that boundary. Preserve the first lower-level result when one exists, because later Player or Encoder errors can hide the original cause.

Evidence and focused verification

Record device-control state and edl entry count; enable device control and supply at least one valid edl entry before retrying multipass. Keep the media object, endpoint, profile, or device identity fixed while changing only that rejected precondition. A successful retest should pass this exact boundary; a different HRESULT from a later stage is new evidence, not recurrence of NS_E_EDL_REQUIRED_FOR_DEVICE_MULTIPASS.
