Capture and Playback

Basic Capture and Playback

Capture a stream with gpa-injector, and play it back with gpa-player. Streams are captured through the duration of the application's lifetime. Basic stream capture requires playback from the beginning of the stream.

Deferred Capture

Deferred Capture, as the name suggests allows stream capture to begin at any point time after a workload is launched via gpa-injector with a keypress (default is L key). The same keybinding can start and stop capture while a workload is injected.

Range Repeat

Select a range in stream and replay continuously (loop N times).

Subcapture

Use gpa-subcapture-recorder to capture a portion of an exsisting stream and create a new stream.

Stream Analysis

Features exposed through the programmatic interfaces.

Metric Collection

Collect hardware metrics for a given range within a stream. Metric collection is requested at playback time through the C++ and Python interfaces.

Experiments

Apply experiments and replay a range with the experiment applied within a stream. Experiments are applied at playback time through the C++ and Python interfaces.

Metadata Extraction

Access metadata information associated with resources. For example, textures can expose format, dimensions, etc.

Resource Extraction

Extract resources from C++ and Python interfaces, including:

Buffers
Textures
Shaders
among other resource types

API Call Inspection

Analyze a stream with the C++ and Python interfaces without requiring playback.

Layers

Heads-Up Display(HUD) Layer

Displays HUD with FPS

Screenshot Layer

Grabs screenshots from the injected application

Logging Layer

Logs API commands from the injected application

Api Debug Layer

Print the output of the current graphics api's debug layer

Device Override Layer

Override the default graphics device and choose another inslalled device

Custom (User) Layers

Creates custom layers and intercepts API calls
