Symptoms

A hotfix is available for Microsoft Media Foundation in Windows 7. This hotfix resolves the following streaming issues that relate to Media Foundation:

Issue 1

You cannot stream some audio files to multiple devices at the same time. These audio files use Audio Compression Manager (ACM) codecs. If the ACM codecs are used for decoding the files, this issue affects the following audio formats: Adaptive Delta Pulse Code Modulation (ADPCM), Mu-law, and Microsoft GSM 6.10 Audio (GSM 610). If the ACM codecs are used for encoding, this issue affects MPEG-1 Audio Layer 3 (MP3).

Issue 2

You trigger an unrecoverable issue when you seek through a digital video in Audio Video Interleave (AVI) format. Therefore, you cannot use video editing.

Issue 3

When you use the Media Foundation (MF) source reader to seek by calling the SetCurrentPosition function, the function fails and you receive an E_INVALIDARG error message. This issue occurs after you perform a dynamic format change.

Issue 4

When you use the MF source reader to decode a video that has dynamic format changes, you encounter a corrupted frame issue or you receive an unrecoverable error. This issue occurs after you perform a dynamic format change.

Issue 5

You enable the Direct3D and the DirectX Video Acceleration (DXVA) decoder for decoding Windows Media Video (WMV) content. After you use the MF source reader to seek through a video, you notice that the frame output of the video from the decoder is incorrect.

Issue 6

You receive an incorrect media type for a stream when you use the MF source reader to obtain the media type. The incorrect media type is not selected for the stream output.

Cause

Cause of Issue 1

This issue occurs because the ACM wrapper only lets one instance of the codecs to be active at a time.

Cause of Issue 2

This issue occurs because Media Foundation only recognizes the first stream even though AVI contains multiple streams.

Cause of Issue 3

This issue occurs because the MF source reader sets an incorrect media type on the media source after you perform a dynamic format change.

Cause of Issue 4

This issue occurs because the MF source reader resets the video sample allocator at the wrong time after you perform a dynamic format change.

Cause of Issue 5

This issue occurs because of an error in the DXVA decoder for WMV content.

Cause of Issue 6

This issue occurs because of an error in the MF source reader.
