Methods

gst_video_info_align

gboolean
gst_video_info_align (GstVideoInfo * info,
                      GstVideoAlignment * align)

Adjust the offset and stride fields in info so that the padding and stride alignment in align is respected.

Multiple views are provided as separate Gst.Memory framebuffers attached to each Gst.Buffer, described by the GstVideoMultiviewMeta and GstVideo.VideoMeta(s)

GST_CAPS_FEATURE_FORMAT_INTERLACED

#define GST_CAPS_FEATURE_FORMAT_INTERLACED "format:Interlaced"

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. GST_VIDEO_BUFFER_FLAG_TOP_FIELD and GST_VIDEO_BUFFER_FLAG_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).
