如何让视频在高并发播放时不卡

需要在上传存储时做处理吗；
加载播放时又要做怎样的处理；
或者说什么....服务器？...不知道，提高带高我是知道的！

之前没有做过视频这块，没有思路！

如何让视频在高并发播放时不卡

需要在上传存储时做处理吗；
加载播放时又要做怎样的处理；
或者说什么....服务器？...不知道，提高带高我是知道的！

之前没有做过视频这块，没有思路！

据朋友说：一个比较长的完整的视频你看到内容虽是一个整体，其实是分段的，在服务器内部以文件分块存储，播放到下一段时又加载下一段的视频文件。如果基于http协议，你在视频网站上看一个120分钟左右的电影，那120分钟的电影整个就一文件不大可能，至于同一段文件同时多人打开观看时的并发问题又是如何处理的我不清楚，再找找资料吧。

问题所提到的所谓“视频高并发时不卡”应该是指即使很多人在线观看，缓冲也十分迅速的意思吧。

如上面所说，分段是很常用的手法之一。

一是，对视频分段储存和传输，Client一侧采用惰性加载的策略，针对看一部分就关掉视频的那些用户可以节省流量。

二是，采用CDN，不赘述了

三是，对视频进行适当的压缩，压制，减少冗余内容，从源头节省流量。

四是，可以采用P2P技术。

想不到了，想到再补充。

How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

How can you use a database to store PHP session data?Apr 27, 2025 am 12:02 AM

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AM

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
