LayerTraceGenerator

Generates layer traces from transaction traces. The tool is a custom surface flinger build that mocks out everything else apart from the front end logic. Transaction traces are written when the transaction is applied, along wth a timestamp and vsync id. The transactions are parsed from proto and applied to recreate the layer state. The result is then written as a layer trace.

Usage:

  1. build and push to device
  2. run ./layertracegenerator [transaction-trace-path] [output-layers-trace-path]
