研究方向
Investigate the encoding pipeline in Kap, focusing on how video frames are processed and encoded. Look at the use of ffmpeg or any native modules for video encoding. The issue mentions artifacts at the bottom edge, which might be related to incorrect frame dimensions or encoding settings. Check recent changes to encoding code and see if there are any open issues or discussions about similar problems.
