VideoInfo

Information describing image properties. This information can be filled in from GstCaps with gstvideo.video_info.VideoInfo.fromCaps. The information is also used to store the specific video info when mapping a video frame with gstvideo.video_frame.VideoFrame.map.

Use the provided macros to access the info in this structure.

Functions

alignFull bool alignFull(gstvideo.video_alignment.VideoAlignment align_, size_t planeSize): Extra padding will be added to the right side when stride alignment padding is required and align will be updated with the new padding values.
align_ bool align_(gstvideo.video_alignment.VideoAlignment align_): Adjust the offset and stride fields in info so that the padding and stride alignment in align is respected.
cPtr void* cPtr(Flag!"Dup" dup)
convert bool convert(gst.types.Format srcFormat, long srcValue, gst.types.Format destFormat, long destValue): Converts among various #GstFormat types. This function handles GST_FORMAT_BYTES, GST_FORMAT_TIME, and GST_FORMAT_DEFAULT. For raw video, GST_FORMAT_DEFAULT corresponds to video frames. This function can be used to handle pad queries of the type GST_QUERY_CONVERT.
copy gstvideo.video_info.VideoInfo copy(): Copy a GstVideoInfo structure.
isEqual bool isEqual(gstvideo.video_info.VideoInfo other): Compares two #GstVideoInfo and returns whether they are equal or not
self VideoInfo self(): Returns this, for use in with statements.
setFormat bool setFormat(gstvideo.types.VideoFormat format, uint width, uint height): Set the default info for a video frame of format and width and height.
setInterlacedFormat bool setInterlacedFormat(gstvideo.types.VideoFormat format, gstvideo.types.VideoInterlaceMode mode, uint width, uint height): Same as #gst_video_info_set_format but also allowing to set the interlaced mode.
toCaps gst.caps.Caps toCaps(): Convert the values of info into a #GstCaps.
