Constants

MF_SOURCE_READERF_ERROR

An error occurred. If you receive this flag, do not make any further calls to IMFSourceReader methods.

MF_SOURCE_READERF_ENDOFSTREAM

The source reader reached the end of the stream.

MF_SOURCE_READERF_NEWSTREAM

One or more new streams were created. Respond to this flag by doing at least one of the following:

• Set the output types on the new streams.
• Update the stream selection by selecting or deselecting streams.

MF_SOURCE_READERF_NATIVEMEDIATYPECHANGED

The native format has changed for one or more streams. The native format is the format delivered by the media source before any decoders are inserted.

MF_SOURCE_READERF_CURRENTMEDIATYPECHANGED

The current media has type changed for one or more streams. To get the current media type, call the IMFSourceReader::GetCurrentMediaType method.

MF_SOURCE_READERF_STREAMTICK

There is a gap in the stream. This flag corresponds to an MEStreamTick event from the media source.

MF_SOURCE_READERF_ALLEFFECTSREMOVED

All transforms inserted by the application have been removed for a particular stream. This could be due to a dynamic format change from a source or decoder that prevents custom transforms from being used because they cannot handle the new media type.
