  • Currently the function have following dependency
    • The processor dedicated knowledge(such as register files, instruction set) for implementing the unwinding function from stack informantion. I have asked the vendor to provide the relative document(manual of instruction set). The vendor basically agreed, and will provide it to us after the legal process done(ETA: 2 weeks).
    • Google breakpad - I only enabled minimal common feature in breakpad to have to compilation passed, will verify it after I get the instruction set manual.
    • The implementation of the class - Sampler in FreeBSD. I am currently use platform-linux.cc as a foundation to implement.

Study

• Read Media_Capture_Depth_Stream_Extension proposal / CTai
  • See https://www.w3.org/wiki/Media_Capture_Depth_Stream_Extension
    • Analysis: Looks like it pass a depth map for JS developer. If TV need a natural interface like hand gesture, we still need a library to translate the depth map result to a developer friendly API.
