} MF_SOURCE_READER_FLAG;

Konstanten

• 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.
