Static gstreamer_video::CAPS_FEATURE_FORMAT_INTERLACED

pub static CAPS_FEATURE_FORMAT_INTERLACED: &GStr

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).
