iptv buffering issue

Fixing a iptv buffering issue can be a daunting task. Internet Protocol Television (IPTV) serves television content over the Internet. Most IPTV customers face the freezing and buffering of channels due to a bad connection or an inefficient server.

Reasons for IPTV some channels freezing problem

In a nutshell, it may have two to several reasons: servers location, or inefficient ram or mysql problems. Although it is suggested most iptv restreamers use dedicated servers with higher capacity, most iptv starters can advisably start with buying a reseller plan as it is much of a lower cost.

For a study case, we have resellers who want to run their own iptv business.

For a good quality no buffering zone it is suggested 500 channels to use at least 3 dedicated servers with minimum capacity excluding the costs of restream per channel, the total overheads cost to break even should be expensive. This is not always the issue, some clients use 1 dedicated of large ram to store 1000 up, but again it is always guaranteed there will anyway be buffering, the idea is to have as many as dedicated servers, as IPTVs are those which deliver the television contents over the IP network. As it works depending on the server and the internet, a lot of factors trigger channel freezing.

The main reasons for freezing and buffering of channels in IPTV services are internet speed, selection of proper middleware, quality of the server, etc.

The first and foremost thing is the internet speed when it comes to loading and freezing problems. Therefore, we always recommend our customers to use a high-speed internet connection to enjoy the IPTV service to its fullest.

Next comes the server hardware as well as the selection of middleware.

How we fixed IPTV buffering issue / some channels freezing problem

IPTV providers get numerous requests from their customers to fix errors. Some of the errors are, stalker portal not loading, the yellow bar got stuck, some channels freezing, epg not working,

1. Internet speed

If the internet speed is low, then the channels won’t load fast and buffering time will be high. So, when customers report problems, we first check for the connectivity speed or atleast use some other or lightweight players to test e.g. vlc media player.

If it is low, we suggest our customers go for a higher internet plan. Also, we confirm whether they are using proper middleware.

2. Selecting Middleware

Next comes the selection of Middleware.

Middlewares are software that acts as a bridge between the operating system and the IPTV applications running on it.

IPTV some channel freezing problem may occur due to wrong middleware selection. So suggest using an IPTV box. It has a built-in WiFi (or antennae attachment) that outputs at a fast enough Mbps to work along with  Ethernet Power Adapter or WiFi booster.

One of the reasons for channel freezing can be the connection of the IPTV box to the internet via WiFi. To overcome this, we suggest our customers use an Ethernet Over Power adapter.

3. Server Quality/ server capacity

Another key factor in the IPTV industry is the quality of the server. The performance of the server matters much in the quality of IPTV service.

Recently, one of our customers approached us saying that he was always facing high load in his server. This resulted in errors and was affecting the users.

On checking, we found that the reason for the high load was that the higher number of online users. The server had only a few processors. And, this was not enough for handling the high MySQL load on the server.

The initial MySQL parameters set on the server appeared as:

So, we made some tweaks in MySQL accordingly. We modified the following values in /etc/mysql/my.cnf.

join_buffer_size =                        under [mysqld]
max_allowed_packet = 16M                  under [mysqldump]
max_allowed_packet = 32M                  under !includedir /etc/mysql/conf.d/
innodb_buffer_pool_size = 256M            under [mysqld] 

Finally, we restarted the MySQL server to apply the new configuration. That fixed the problem and the server started working fine.


In a nutshell, our Support Engineers fix IPTV some channels freezing problems by ensuring internet speed, quality of middleware,  and by tweaking the configuration of the server.
