} AM_SEEKING_SEEKING_CAPABILITIES;

Members

  • AM_SEEKING_CanSeekAbsolute
    Stream can seek to an absolute position.
  • AM_SEEKING_CanSeekForwards
    Stream can seek forward.
  • AM_SEEKING_CanSeekBackwards
    Stream can seek backward.
  • AM_SEEKING_CanGetCurrentPos
    Stream can report its current position.
  • AM_SEEKING_CanGetStopPos
    Sstream can report its stop position.
  • AM_SEEKING_CanGetDuration
    Stream can report its duration.
  • AM_SEEKING_CanPlayBackwards
    Stream can play backward.
  • AM_SEEKING_Source
    Reserved.
  • AM_SEEKING_CanSkipForwards
    Stream can skip to the next item in a server-side playlist. Used with the IMediaSeeking2 Interface.
  • AM_SEEKING_CanSkipBackwards
    Stream can skip to the previous item in a server-side playlist. Used with the IMediaSeeking2 Interface.
  • AM_SEEKING_CanSkipValid
    Stream can skip an item in a server-side playlist. Used with the IMediaSeeking2 Interface.
  • AM_SEEKING_CanResetPlaylist
    Server-side playlist can be reset to start of the playlist.

Remarks

In certain server-side playlist (SSPL) scenarios, the application needs to know whether skipping is valid; for example, when skipping is not supported by the server, or if the SSPL is embedded in a client-side playlist that does not support skipping. In this case, the application can check the AM_SEEKING_CanSkipValid flag to determine if skipping is valid.

This enumeration is used by the IMediaSeeking::GetCapabilities method.
