Title

Feature Request: Support Perfetto Protobuf Input

Body

Please integrate support for Perfetto Protobuf input. This offers two key advantages:

  1. Eliminates RAM Limitations: Protobuf allows streaming data directly to disk as the program runs (e.g., flushing every 1MB). This avoids the memory overhead of storing the entire trace in RAM before writing.
  2. Compact File Size: The binary format is significantly smaller than textual output.
