Enum gstreamer_video::VideoInterlaceMode

#[non_exhaustive]
pub enum VideoInterlaceMode {
    Progressive,
    Interleaved,
    Mixed,
    Fields,
    Alternate,
}

The possible values of the VideoInterlaceMode describing the interlace mode of the stream.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Progressive

all frames are progressive

Interleaved

2 fields are interleaved in one video frame. Extra buffer flags describe the field order.

Mixed

frames contains both interlaced and progressive video, the buffer flags describe the frame and fields.

Fields

2 fields are stored in one buffer, use the frame ID to get access to the required field. For multiview (the ‘views’ property > 1) the fields of view N can be found at frame ID (N * 2) and (N * 2) + 1. Each field has only half the amount of lines as noted in the height property. This mode requires multiple GstVideoMeta metadata to describe the fields.

Alternate

1 field is stored in one buffer, GST_VIDEO_BUFFER_FLAG_TF or GST_VIDEO_BUFFER_FLAG_BF indicates if the buffer is carrying the top or bottom field, respectively. The top and bottom buffers must alternate in the pipeline, with this mode (Since: 1.16).
