setVideoSource method

Future<bool> setVideoSource(VideoSource source)

设置视频源

sourceType 视频源类型 source 视频源 如果sourceType为VideoSourceType.VIDEO_FILE_SOURCE source应该为文件路径

如果sourceType为VideoSourceType.VIDEO_LIVE_SOURCE source应该为设备指针

如果sourceType为VideoSourceType.VIDEO_CARD_SOURCE source应该为设备指针

如果sourceType为VideoSourceType.VIDEO_NETWORK_SOURCE source应该为下载地址
