根据日志显示，首帧渲染后视频无法播放，可能是由于快速频繁切换视频导致播放器资源未能及时释放，建议您尝试以下解决方案：
-
确保在切换视频时，先停止当前视频的播放，再播放下一个视频，避免资源冲突。
-
尝试使用播放器的缓存功能，将视频缓存到本地，以减轻服务器负担，提高播放速度。

建议不使用AVPCacheConfig边播边缓存，目前我们不推荐使用，建议使用文档: https://help.aliyun.com/document_detail/124716.html "性能->本地缓存"中的全局本地缓存。start应该是在收到prepareDone的时候调用的。此回答整理自钉群“阿里云-VOD-视频点播-技术交流（进群先看公告）”
