Abstract: Various aspects of the present disclosure provide for detecting a condition indicating that a graphics processing unit (GPU) is in an unstable state while receiving GPU commands in a first wireless display mode, transmitting a GPU refresh request message and switching from the first wireless display mode to a second wireless display mode in response to detecting the condition, receiving data sufficient to reset the GPU from the unstable state to a stable state at a random access point (RAP) in a trace of the GPU commands, and switching from the second wireless display mode to the first wireless display mode after receiving the data. The GPU refresh request message may include information requesting the data sufficient to reset the GPU at an upcoming RAP in the trace of the GPU commands. Various other aspects are also provided throughout the present disclosure.

Abstract: In one example, a method for transmitting video data includes capturing a plurality of sets of graphical command tokens respectively renderable into a plurality of frames of video data; and responsive to determining that a length of a current set of graphical command tokens of the plurality of sets of graphical command tokens is the same as a length of a previous set of the plurality of sets of graphical command tokens, outputting, by a source device and to a sink device, a compressed version of the current set of graphical command tokens.

Abstract: In one example, a method for processing video data includes receiving, by a sink device and from a source device, one or more graphical command tokens that are executable to render original video data; modifying, by the sink device, the graphical command tokens to generate modified graphical command tokens that are executable to render modified video data different from the original video data; and outputting, for presentation at a display operatively connected to the sink device, the modified video data.

Abstract: In one example, a method for transmitting video data includes outputting, by a source device to a sink device, graphical commands and one or more texture elements that are renderable into video data. In this example, outputting a particular texture element of the one or more texture elements includes streaming, by the source device and to the sink device, a plurality of stages that each respectively correspond to a respective subset of pixels of the particular texture element.

Abstract: Various aspects of the present disclosure provide for a first device that may establish a wireless docking session with a second device. The first device may determine whether a profile of a second device matches a profile stored in the first device. When such a match exists, the first device may export data to the second device in a format associated with the profile of the second device. When such a match does not exist, the first device may provide an error message or export data to the second device in a format associated with a default profile of the first device. The profile may indicate an operating system, a peripheral component, a display size, a display resolution, a touch screen-capability, a font type, a user setting, a power source or availability, a hardware component, or a software module. Additional aspects, embodiments, and features are also provided herein.
