/**
* GstBufferFlags:
- * @GST_BUFFER_FLAG_LIVE: the buffer is live data and should be discarded in
- * the PAUSED state.
- * @GST_BUFFER_FLAG_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.
- * @GST_BUFFER_FLAG_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.
- * @GST_BUFFER_FLAG_RESYNC: the buffer timestamps might have a discontinuity
- * and this buffer is a good point to resynchronize.
- * @GST_BUFFER_FLAG_CORRUPTED: the buffer data is corrupted.
- * @GST_BUFFER_FLAG_MARKER: the buffer contains a media specific marker. for
- * video this is typically the end of a frame boundary, for audio
- * this is usually the start of a talkspurt.
- * @GST_BUFFER_FLAG_HEADER: the buffer contains header information that is
- * needed to decode the following data.
- * @GST_BUFFER_FLAG_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).
- * @GST_BUFFER_FLAG_DROPPABLE: the buffer can be dropped without breaking the
- * stream, for example to reduce bandwidth.
- * @GST_BUFFER_FLAG_DELTA_UNIT: this unit cannot be decoded independently.
- * @GST_BUFFER_FLAG_TAG_MEMORY: this flag is set when memory of the buffer
- * is added/removed
- * @GST_BUFFER_FLAG_SYNC_AFTER: Elements which write to disk or permanent
+ * @GST_BUFFER_FLAG_LIVE: the buffer is live data and should be discarded in

+ * @GST_BUFFER_FLAG_LAST: additional media specific flags can be added starting from

+ * @GST_BUFFER_FLAG_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. (Since 1.14)
