No description available in the introspection data.

pattern CAPS_FEATURE_FORMAT_INTERLACED :: Text

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. gSTVIDEOBUFFERFLAGTOPFIELD and gSTVIDEOBUFFERFLAGBOTTOMFIELD 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 gSTVIDEOINFOFIELDRATEN).

Since: 1.16.

When this option is enabled on the bufferpool, BUFFER_POOL_OPTION_VIDEO_META should also be enabled.
