MTP Compliance Test - Requirements - Media Players

This test validates compliance with the Media Transfer Protocol (MTP), Revision 1.0.

This test makes sure that devices that use the MTP class driver comply with MTP implementation standards. This test is directed at portable media player devices that connect by using the MTP. This test validates compliance with defined protocols based on requirements that are documented in the Windows Certification Program.

Note

This test does not cover the following items:

  • Digital rights management (DRM) validation

  • Devices that use proprietary (third-party) drivers that work with the Windows Portable Device (WPD) driver stack

  • Devices that are not PTP or MTP-based

Running the test

Before you run the test, complete the test setup as described in the test requirements: Device.Portable Testing Prerequisites.

The MTP device should be active and plugged in before commencing the test. The tool Mtpinfup.exe will update the driver for the attached MTP device to a signed test .inf file Mtptest.inf. Upon completion of the test, Mtpinfup.exe will update the driver back to the original in-box driver Wpdmtp.inf. If an optional capability is not supported by the device, the test will skip that test case.

Troubleshooting

For troubleshooting information, see Troubleshooting Device.Portable Testing.

More information

This test requires that a MTP-compatible device is installed. The test is fully automated with Pass/Fail results for each requirement.

This test is divided into the following functional categories:

  • Device Capabilities tests

  • Operations tests

  • Device Properties

  • Object Property tests

Each of the functional categories mentioned above contain child test cases, testing the sub components that fall under the corresponding category.

The test will validate that the following Operations are supported by the device:

  • OpenSession

  • CloseSession

  • GetDeviceInfo

  • GetStorageIDs

  • GetStorageInfo

  • GetObject

  • GetDevicePropDesc

  • GetDevicePropValue

  • SetDevicePropValue

  • DeleteObject

  • SendObject

  • GetNumObjects

  • GetObjectHandles

  • GetObjectInfo

  • SendObjectInfo

  • GetPartialObject

  • GetObjectPropsSupported

  • GetObjectPropDesc

  • GetObjectPropValue

  • SetObjectPropValue

  • GetObjectReferences

  • SetObjectReferences

The test validates that the following device properties are supported:

  • Synchronization Partner

  • Device Friendly Name

The test validates that the following formats are supported:

  • Undefined

  • Association

  • AbstractAudioAlbum

  • AbstractAudioVideoPlaylist

For AbstractAudioAlbum, the following properties are verified:

  • Genre

  • AlbumArtist

The test validates that the following Object Properties are supported for each supported format:

  1. StorageID

  2. ObjectFormat

  3. ProtectionStatus

  4. ObjectSize

  5. ObjectFileName

  6. ParentObject

  7. PersistentUniqueObjectIdentifier

  8. Name

  9. Non-Consumable

For supported Image formats, the test looks for these additional Object Properties:

  • Width

  • Height

For supported Video formats, the test looks for these additional Object Properties:

  • Width

  • Height

  • SampleRate

  • NumberOfChannels

  • ScanType

  • Audio WAVE CODEC

  • AudioBitRate

  • VideoFourCCCodec

  • VideoBitrate

  • Frames PerThousand Second

  • Encoding Profile

For supported Audio formats, the test looks for these additional Object Properties:

  • Artist

  • Track

  • AlbumName

  • AlbumArtist

  • SampleRate

  • NumberOfChannels

  • AudioBitRate

  • AudioWaveCodec

All other supported operations, device properties, and object properties are considered optional and therefore will be validated according to implementation details defined in the Picture Transfer Protocol (PTP) for Digital Still Photography Devices, Version 1.0 (PIMA15740) and Media Transfer Protocol (MTP), Revision 1.0.

Run time:

Test duration depends on the number of supported capabilities, formats, and operations. Run time can vary up to 2 hours.
