Q1. At the current resolution of 1280*1024 and with a bandwidth of 2 Mbps, I-frames tend to be too small while P-frames are relatively large. This results in a visual effect where each GOP causes the image to flicker for one frame. How can this issue be avoided?
Q2. Besides the QP value, what other parameters can enhance the quality of the compressed image? How can we preserve image details as much as possible under low bitrate conditions?
