Hawkeye - FPS Trace

FPS Trace records the FPS value and provides a floating window widget to display the FPS.

If GPUImage is used as the camera output, the framebuffer present FPS is also provided by FPS Trace.

The default recording interval of FPS is 0.5 second. If a record is equal to half a second ago, then only turn on (default off) statusFlushKeepRedundantRecords in MTHawkeyeUserDefaults, FPS Trace will record the new one, otherwise will skip. While readout, you may have to fill the empty equal records in timeline by yourself.

Storage

When FPS Trace is add to MTHawkeyeClient, FPS value will be store in Records file once it needed.

it use fps as the collection name (while gl-fps for GPUImage framebuffer present), key is the time record, value is the FPS value.
