/**

* GstBufferFlags:
|
||||
* @GST_BUFFER_FLAG_LIVE: the buffer is live data and should be discarded in
|
||||
* the PAUSED state.
|
||||
* @GST_BUFFER_FLAG_DROP: 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 timestamp 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 end 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_DELTA_UNIT: this unit cannot be decoded independently.
|
||||
* @GST_BUFFER_FLAG_IN_CAPS: the buffer has been added as a field in a #GstCaps.
|
||||
* @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
|

* 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_IN_CAPS: the buffer has been added as a field in a #GstCaps.
|

*
|

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