NS_E_DEVICE_NOT_SUPPORT_FORMAT
How to investigate NS_E_DEVICE_NOT_SUPPORT_FORMAT
The code 0xC00D0FA3 narrows the event to checking whether the device advertises support for the item’s media format. Retain the first lower-level error.
What the Player is doing
A device shown in Explorer can still disappear from the Player’s WMDM session or reject a media format, filename, directory operation or storage request. A realistic trigger is that the file plays on the PC but its codec is absent from the device capability list.
Capture before changing state
| Evidence | Why it matters |
|---|---|
| Producing object and operation | PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT |
| Key observation | source format, device GetFormatSupport result, codec/FourCC and storage capabilities |
| Controlled comparison | Repeat the producing call after changing only this condition: transcode to an advertised format or omit the incompatible item. |
Five-step isolation test
- Capture
0xC00D0FA3, the exact Player/API operation and the first timestamp at which it appears. - Save source format, device GetFormatSupport result, codec/FourCC and storage capabilities; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- Correlate the result with PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT.
- Reproduce once with the original source and destination, then apply only this change: transcode to an advertised format or omit the incompatible item.
- Start a fresh operation and verify that the original call advances without returning
NS_E_DEVICE_NOT_SUPPORT_FORMAT.
Different conditions in the same family
| Related result | Different condition |
|---|---|
NS_E_DEVICE_DISCONNECTED | using a portable-device object after its physical connection was removed |
NS_E_DEVICE_IS_NOT_READY | opening device storage before the service provider reports a ready state |
NS_E_PDA_UNSUPPORTED_FORMAT | validating a portable-device operation against the object’s format |
Correction criteria
The test is successful when you transcode to an advertised format or omit the incompatible item, recreate the owning operation, and the original call no longer returns it.
During verification, do not assume the old interface pointer remains valid after reconnect; Re-enumerate the device and storage objects and correlate the failure with the same connection generation.
