Benchmarking and Profiling Techniques

Benchmarking and profiling are two crucial steps in optimizing any software, including the kmp external codec libvlcjni.so. They help us identify performance bottlenecks and the areas where we can make improvements to speed up video decoding.

Benchmarking is the process of measuring the performance of a piece of software. We’re going to compare how efficient the codec is before and after optimization. This can be done using benchmarking tools, which measure the load time, frame rate, and the overall quality of video playback.

On the other hand, profiling is about identifying where the most time is spent during the execution of your code. It helps us zoom in on the parts of the codec that need optimization. Profilers provide data on function call counts, CPU time usage, and memory usage, all of which are critical when optimizing for arm64-v8a CPUs.

By combining the results from benchmarking and profiling, we can gain insights into what needs optimization and how effective our optimizations have been. It’s all about continuous improvement – we learn, we optimize, we measure, and we repeat. This iterative process ensures that we are always striving for the best performance.
