cli-anything-renderdoc

Command-line interface for RenderDoc graphics debugger.

Provides headless, scriptable analysis of GPU frame captures (.rdc files) without requiring the RenderDoc GUI.

Installation

cd renderdoc/agent-harness
pip install -e .

Prerequisites: RenderDoc must be installed and its Python module must be importable. Add the RenderDoc Python directory to PYTHONPATH:

# Windows (typical)
set PYTHONPATH=C:\Program Files\RenderDoc
# Linux (typical)
export PYTHONPATH=/opt/renderdoc/lib

Quick Start

# Show capture info
cli-anything-renderdoc --capture frame.rdc capture info

# List all draw calls
cli-anything-renderdoc -c frame.rdc actions list --draws-only

# Get action summary
cli-anything-renderdoc -c frame.rdc actions summary

# Save a texture as PNG
cli-anything-renderdoc -c frame.rdc textures save <resourceId> -o output.png

# Pick a pixel
cli-anything-renderdoc -c frame.rdc textures pick <resourceId> 100 200

# Get pipeline state at a draw call
cli-anything-renderdoc -c frame.rdc pipeline state 42

# Get shader disassembly
cli-anything-renderdoc -c frame.rdc pipeline shader-export 42 --stage Fragment

# List GPU counters
cli-anything-renderdoc -c frame.rdc counters list

# Read buffer data
cli-anything-renderdoc -c frame.rdc resources read-buffer <resourceId> --format float32

# JSON output for all commands
cli-anything-renderdoc -c frame.rdc --json actions list
