BufferFlags
===================================================================

.. currentmodule:: gi.repository.Gst





.. class:: BufferFlags
   :no-contents-entry:






A set of buffer flags used to describe properties of a :obj:`~gi.repository.Gst.Buffer`.













Fields
------

.. rst-class:: interim-class

.. class:: BufferFlags
   :no-index:
   

   .. attribute:: CORRUPTED

      The buffer data is corrupted.







   .. attribute:: DECODE_ONLY

      The buffer contains data that should be dropped
      because it will be clipped against the segment
      boundaries or because it does not contain data
      that should be shown to the user.







   .. attribute:: DELTA_UNIT

      This unit cannot be decoded independently.







   .. attribute:: DISCONT

      The buffer marks a data discontinuity in the stream.
      This typically occurs after a seek or a dropped buffer
      from a live or network source.







   .. attribute:: DROPPABLE

      The buffer can be dropped without breaking the
      stream, for example to reduce bandwidth.







   .. attribute:: GAP

      The buffer has been created to fill a gap in the
      stream and contains media neutral data (elements can
      switch to optimized code path that ignores the buffer
      content).







   .. attribute:: HEADER

      The buffer contains header information that is
      needed to decode the following data.







   .. attribute:: LAST

      Additional media specific flags can be added starting from
      this flag.







   .. attribute:: LIVE

      The buffer is live data and should be discarded in
      the PAUSED state.







   .. attribute:: MARKER

      The buffer contains a media specific marker. for
      video this is the end of a frame boundary, for audio
      this is the start of a talkspurt. for RTP
      packets this matches the marker flag in the
      RTP packet header.







   .. attribute:: NON_DROPPABLE

      This buffer is important and should not be dropped.

      This can be used to mark important buffers, e.g. to flag RTP packets
      carrying keyframes or codec setup data for RTP Forward Error Correction
      purposes, or to prevent still video frames from being dropped by elements
      due to QoS.



      .. versionadded:: 1.14





   .. attribute:: RESYNC

      The buffer timestamps might have a discontinuity
      and this buffer is a good point to resynchronize.







   .. attribute:: SYNC_AFTER

      Elements which write to disk or permanent storage should ensure the data
      is synced after writing the contents of this buffer.



      .. versionadded:: 1.6





   .. attribute:: TAG_MEMORY

      This flag is set when memory of the buffer
      is added/removed
