GstVideoBarMeta

Bar data should be included in video user data whenever the rectangular picture area containing useful information does not extend to the full height or width of the coded frame and AFD alone is insufficient to describe the extent of the image.

Note: either vertical or horizontal bars are specified, but not both.

Variables

barData1
uint barData1;

If @is_letterbox is true, then the value specifies the last line of a horizontal letterbox bar area at top of reconstructed frame. Otherwise, it specifies the last horizontal luminance sample of a vertical pillarbox bar area at the left side of the reconstructed frame

barData2
uint barData2;

If @is_letterbox is true, then the value specifies the first line of a horizontal letterbox bar area at bottom of reconstructed frame. Otherwise, it specifies the first horizontal luminance sample of a vertical pillarbox bar area at the right side of the reconstructed frame.

field
ubyte field;

0 for progressive or field 1 and 1 for field 2

isLetterbox
bool isLetterbox;

if true then bar data specifies letterbox, otherwise pillarbox
