SYSTEMS, METHODS, AND DEVICES FOR GENERATION OF VIDEO CONTENT
Systems, methods, and devices generate video data for graphics displays. Methods include receiving, at a video buffer, a video input comprising video data, the video data being included in a video frame, reading at least some of the video data out of the buffer based, at least in part, on a first offset value, and performing, using one or more processors, one or more graphics rendering operations on the video data. Methods also include writing rendered video data to a line buffer based, at least in part, on a second offset value, and generating a video output based, at least in part, on one or more warping operations, the video output being synchronous with the video input.
1 . A method comprising:
receiving, at a video buffer, a video input comprising video data, the video data being included in a video frame;
reading at least some of the video data out of the buffer based, at least in part, on a first offset value;
performing, using one or more processors, one or more graphics rendering operations on the video data;
writing rendered video data to a line buffer based, at least in part, on a second offset value; and
generating a video output based, at least in part, on one or more warping operations, the video output being synchronous with the video input.
2 . The method of claim 1 , wherein the first offset value is determined based on a current read position and a current write position associated with the video buffer.
3 . The method of claim 2 , wherein the second offset value is determined based on a current write position associated with the video buffer and a current write position associated with the line buffer.
4 . The method of claim 1 further comprising:
synchronizing frame generation of a display controller with the receiving of the video input.
5 . The method of claim 1 , wherein the one or more warping operations are performed on-the-fly.
6 . The method of claim 1 , wherein the one or more warping operations are performed based on a designated warping map configured based on an interior of an automobile.
7 . The method of claim 2 , wherein the video output is provided to a heads-up display of an automobile.
8 . The method of claim 1 , wherein the one or more graphics rendering operations are performed by a blit engine.
9 . The method of claim 1 , wherein the generating of the video output further comprises:
generating a video frame based on rendered and warped video data.
10 . A system comprising:
a memory comprising:
a video buffer configured to receive a video input comprising video data, the video data being included in a video frame; and
a line buffer; and
a graphics controller comprising one or more processors configured to:
read at least some of the video data out of the buffer based, at least in part, on a first offset value;
performing one or more graphics rendering operations on the video data;
writing rendered video data to the line buffer based, at least in part, on a second offset value; and
generate a video output based, at least in part, on one or more warping operations, the video output being synchronous with the video input.
11 . The system of claim 10 , wherein the first offset value is determined based on a current read position and a current write position associated with the video buffer.
12 . The system of claim 11 , wherein the second offset value is determined based on a current write position associated with the video buffer and a current write position associated with the line buffer.
13 . The system of claim 10 , wherein the one or more processors are further configured to:
synchronize frame generation of a display controller with the receiving of the video input.
14 . The system of claim 10 , wherein the one or more warping operations are performed based on a designated warping map configured based on an interior of an automobile.
15 . The system of claim 10 , wherein the one or more graphics rendering operations are performed by a blit engine.
16 . A device comprising:
a video buffer configured to receive a video input comprising video data, the video data being included in a video frame;
a line buffer; and
one or more processors configured to:
read at least some of the video data out of the buffer based, at least in part, on a first offset value;
performing one or more graphics rendering operations on the video data;
writing rendered video data to the line buffer based, at least in part, on a second offset value; and
generate a video output based, at least in part, on one or more warping operations, the video output being synchronous with the video input.
17 . The device of claim 16 , wherein the first offset value is determined based on a current read position and a current write position associated with the video buffer.
18 . The device of claim 17 , wherein the second offset value is determined based on a current write position associated with the video buffer and a current write position associated with the line buffer.
19 . The device of claim 16 , wherein the one or more processors are further configured to:
synchronize frame generation of a display controller with the receiving of the video input.
20 . The device of claim 16 , wherein the one or more warping operations are performed based on a designated warping map configured based on an interior of an automobile.
