Struct gstreamer::BufferFlags[][src]

pub struct BufferFlags { /* fields omitted */ }
Expand description

A set of buffer flags used to describe properties of a Buffer.

Implementations

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

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.

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.

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

the buffer data is corrupted.

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.

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

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).

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

this unit cannot be decoded independently.

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

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

This is supported on crate feature v1_14 only.

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.

Returns an empty set of flags

Returns the set containing all flags.

Returns the raw value of the flags currently stored.

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Returns true if no flags are currently stored.

Returns true if all flags are currently set.

Returns true if there are flags common to both self and other.

Returns true all of the flags in other are contained within self.

Inserts the specified flags in-place.
