Returns the DM regex to match the specified lottie file name.

— def parse_trace(trace_json, lottie_filename, api):

parse_trace parses the specified trace JSON.

Parses the trace JSON and calculates the time of a single frame. Frame time is considered the same as seek time + render time. Note: The first seek is ignored because it is a constructor call.

A dictionary is returned that has the following structure: { 'frame_max_us': 100, 'frame_min_us': 90, 'frame_avg_us': 95, }

— def perf_steps(api):

Run DM on lottie files with tracing turned on and then parse the output.
