Static gstreamer_video::CAPS_FEATURE_FORMAT_INTERLACED [−][src]
pub static CAPS_FEATURE_FORMAT_INTERLACED: Lazy<&'static str>
This is supported on crate feature
v1_16
only.Expand description
Name of the caps feature indicating that the stream is interlaced.
Currently it is only used for video with ‘interlace-mode=alternate’
to ensure backwards compatibility for this new mode.
In this mode each buffer carries a single field of interlaced video.
VideoBufferFlags::TOP_FIELD
and VideoBufferFlags::BOTTOM_FIELD
indicate whether the buffer carries a top or bottom field. The order of
buffers/fields in the stream and the timestamps on the buffers indicate the
temporal order of the fields.
Top and bottom fields are expected to alternate in this mode.
The frame rate in the caps still signals the frame rate, so the notional field
rate will be twice the frame rate from the caps
(see GST_VIDEO_INFO_FIELD_RATE_N
).
