This library provides an interface to the vcu_qt application for reading VCU encoder/decoder memory throughput performance numbers.
The programming model:
1.Calls perf_monitor_init() on startup.
2.Periodically calls perf_monitor_get_rd_wr_cnt() for each VCU APM. This API returns the number of read+write transactions happening on the AXI Performance Monitor port in bytes.
3.Calls perf_monitor_deinit() on exit.
