based on defined performance objectives to determine whether the system meets performance requirements, at the same time, you can analyze the System Bottleneck Based on the stress test results, and then perform corresponding optimization. There are still a lot of tools that can be used for stress testing, such as LoadRunner and jmeter, however, the stress testing topic is too big. I will not talk about it here, but I don't know much about it. Analyze System performance bottlenecks Based on th

function is mb_pred_p_inter16x16 (), where PERFORM_MC () is called to complete motion compensation. For one-way motion compensation, PERFORM_MC () calls Perform_mc_single (), and for bidirectional motion compensation, PERFORM_MC () invokes Perform_mc_bi (). During motion compensation, Get_block_luma () is called to complete the interpolation work of one-fourth pixels.Regardless of the inter type macro block or the intra type macro block, the final call to imbtrans4x4 () completes the DCT invers
