+Version
+
+    Version 5 - May 20, 2019
+
+Number
+
+    134
+
+Extension Type
+
+    EGL display extension
+
+Dependencies
+
+    Requires the EGL_KHR_stream extension.
+
+    This extension is written based on the wording of version 26 of the
+    EGL_KHR_stream extension.
+
+Overview
+
+    EGL does not define a frame orientation.  However, window systems or
+    rendering APIs might.
+
+    Ideally, when using EGL streams, frame orientation is agreed upon by
+    both the connected consumer and producer and appropriate handling is
+    performed within EGL to satisfy both endpoints needs.  Thus,
+    applications will rarely have to worry about frame orientation.
+
+    However, in some cases consumer applications such as compositors
+    might still need to access the frame data as provided by the
+    consumer.  Hence, they need to know what orientation was set for the
+    stream frames.  This will allow applications to adjust the way they
+    access the frame data.
+
+    Similarly, producer applications might need to adjust how rendering
+    commands are issued depending on the orientation set for the stream
+    frames.
+
+    This extension provides new attributes to allow EGL stream users to
+    query frame orientation and whether it is handled automatically by
+    the producer or consumer endpoints so that clients are not required
+    to take further actions.
+
+New Functions
+
+    None.
+

+in EGL_KHR_stream:
+
+    3.10.4.x EGL_STREAM_FRAME_ORIGIN_X_NV
+
+    EGL_STREAM_FRAME_ORIGIN_X_NV is a read-only attribute that
+    indicates the position on the X axis of the origin relative to the
+    stream images surface as agreed upon by consumer and producer.
+
+    The relative position on X may be one of the following:
+
+        - EGL_LEFT_NV - Coordinates on the X axis will be 0 on the left
+          border and increase towards the right border until <frame
+          width> is reached.
+
+        - EGL_RIGHT_NV - Coordinates on the X axis will be <frame width>
+          on the left border and decrease towards the right border until
+          0 is reached.
+
+        - EGL_DONT_CARE - No orientation on the X axis was set by the EGL
+          implementation.  Applications must coordinate what they are
+          doing.
+
+    EGL_STREAM_FRAME_ORIGIN_X_NV will not be defined until a consumer
+    and a producer are connected to the stream.  Querying it before that
+    will generate an EGL_BAD_STATE_KHR error.
+
+
+    3.10.4.x+1 EGL_STREAM_FRAME_ORIGIN_Y_NV
+
+    EGL_STREAM_FRAME_ORIGIN_Y_NV is a read-only attribute that
+    indicates the position on the Y axis of the origin relative to the
+    stream images surface as agreed upon by consumer and producer.
+
+    The relative position on Y may be one of the following:
+
+        - EGL_TOP_NV - Coordinates on the Y axis will be 0 on the top
+          border and increase towards the bottom border until <frame
+          height> is reached.
+
+        - EGL_BOTTOM_NV - Coordinates on the Y axis will be <frame
+          height> on the top border and decrease towards the bottom
+          border until 0 is reached.
+
+        - EGL_DONT_CARE - No orientation on the Y axis was set by the EGL
+          implementation.  Applications must coordinate what they are
+          doing.
+
+    EGL_STREAM_FRAME_ORIGIN_Y_NV will not be defined until a consumer
+    and a producer are connected to the stream.  Querying it before that
+    will generate an EGL_BAD_STATE_KHR error.
+
+
+    3.10.4.x+2 EGL_STREAM_FRAME_MAJOR_AXIS_NV
+
+    EGL_STREAM_FRAME_MAJOR_AXIS_NV is a read-only attribute that
+    indicates whether the stream images are X-major or Y-major.
+
+    The major axis may be one of the following:
+
+        - EGL_X_AXIS_NV - Frames are laid out such that consecutive
+          pixels with same Y coordinate reside next to each other in
+          memory.
+
+        - EGL_Y_AXIS_NV - Frames are laid out such that consecutive
+          pixels with same X coordinate reside next to each other in
+          memory.
+
+        - EGL_DONT_CARE - No major axis was set by the EGL
+          implementation.  Applications must coordinate what they are
+          doing.
+
+    EGL_STREAM_FRAME_MAJOR_AXIS_NV will not be defined until a consumer
+    and a producer are connected to the stream.  Querying it before that
+    will generate an EGL_BAD_STATE_KHR error.
+
+
+    3.10.4.x+3 EGL_CONSUMER_AUTO_ORIENTATION_NV
+
+    EGL_CONSUMER_AUTO_ORIENTATION_NV is a read-only attribute that
+    indicates whether the consumer endpoint will handle frame orientation
+    automatically so that the consumer application is not required to
+    take further actions.
+
+    The following values can be returned:
+
+        - EGL_TRUE - The consumer application can read frames as normal.
+          The consumer will flip images as needed if the expected
+          orientation does not match.
+
+        - EGL_FALSE - The consumer application is expected to query the
+          frame orientation and process images accordingly if it does not
+          match with the expected orientation.
+
+    EGL_CONSUMER_AUTO_ORIENTATION_NV will not be defined until a consumer
+    and a producer are connected to the stream.  Querying it before that
+    will generate an EGL_BAD_STATE_KHR error.
+
+
+    3.10.4.x+4 EGL_PRODUCER_AUTO_ORIENTATION_NV
+
+    EGL_PRODUCER_AUTO_ORIENTATION_NV is a read-only attribute that
+    indicates whether the producer endpoint will handle frame orientation
+    automatically so that the producer application is not required to
+    take further actions.
+
+    The following values can be returned:
+
+        - EGL_TRUE - The producer application can generate frames as
+          normal.  The producer will flip images as needed if the
+          expected orientation does not match.
+
+        - EGL_FALSE - The producer application is expected to query the
+          frame orientation and generate images accordingly if it does
+          not match with the expected orientation.
+
+    EGL_PRODUCER_AUTO_ORIENTATION_NV will not be defined until a consumer
+    and a producer are connected to the stream.  Querying it before that
+    will generate an EGL_BAD_STATE_KHR error.
+
+
+Add to the error list in section "3.10.4.2 Querying EGLStream
+Attributes":
+
+    - EGL_BAD_STATE_KHR is generated if <attribute> is any of
+      EGL_STREAM_FRAME_ORIGIN_X_NV, EGL_STREAM_FRAME_ORIGIN_Y_NV,
+      EGL_STREAM_FRAME_MAJOR_AXIS_NV, EGL_CONSUMER_AUTO_ORIENTATION_NV,
+      or EGL_PRODUCER_AUTO_ORIENTATION_NV and the stream is in
+      EGL_STREAM_STATE_CREATED_KHR or EGL_STREAM_STATE_CONNECTING_KHR
+      state.
+
+Issues
+
+    1. Frame orientation is only needed for and relevant to specific
+       consumers and producers.  What should the query of either
+       EGL_STREAM_FRAME_ORIGIN_X_NV, EGL_STREAM_FRAME_ORIGIN_Y_NV,
+       EGL_STREAM_FRAME_MAJOR_AXIS_NV when consumers or producers that do
+       not define a frame orientation are connected to the stream?
+
+       RESOLVED: If the consumer or producer connected to the stream does
+       not define a frame orientation, the queries will return
+       EGL_DONT_CARE and applications must coordinate what they do.
+
+    2. What should the query return when the connected consumer or
+       producer defines a frame orientation but can actually handle any?
+
+       RESOLVED: Quering EGL_STREAM_FRAME_ORIGIN_X_NV,
+       EGL_STREAM_FRAME_ORIGIN_Y_NV, or EGL_STREAM_FRAME_MAJOR_AXIS_NV
+       will return the default frame orientation.
+
+       Querying EGL_CONSUMER_AUTO_ORIENTATION_NV or
+       EGL_PRODUCER_AUTO_ORIENTATION_NV will return whether the consumer
+       or producer can handle any orientation automatically so that
+       applications do not need to worry about it.
+
+       If querying EGL_CONSUMER_AUTO_ORIENTATION_NV or
+       EGL_PRODUCER_AUTO_ORIENTATION_NV returns EGL_FALSE, the
+       corresponding application is expected to query the frame
+       orientation and take the appropriate action if that does not match
+       the expected orientation.
