3.2.4 SDP Media Attribute Transform

Depending on product model, the SDP file may contain a video media attribute transform. If the streamed video is rotated or mirrored from the image source, this video media attribute shows how the video stream is orientated in relation to the original image configuration. The orientation is described by a transformation matrix consisting of homogeneous coordinates for two-dimensional operations (a 3x3 matrix).

Syntax:

a=transform:<MATRIX>

The matrix is formatted using commas to separate columns and semicolons to separate rows.

Example 2:

A video stream which is rotated 90 degrees is described by:
