live_ksmp_comp_level
The `live_ksmp_comp_level` directive configures the compression level for Kaltura Segment Media Protocol (KSMP) streaming.
Description
The live_ksmp_comp_level directive is a configuration option within the Kaltura Media Framework Common NGINX Module, aimed at optimizing live media streaming performance by managing the compression levels applied during media transmission. It accepts a single argument, which specifies the desired compression level for the streamed content using the KSMP. It is essential for tuning the balance between stream quality and bandwidth usage, especially in environments where network conditions vary significantly.
This directive can be set in different contexts—http, server, or location—allowing for diverse configuration scopes depending on the requirements of the application. Depending on the value provided, it influences how the media segments are packed before being sent over the network, potentially reducing latency or increasing throughput. Users need to select the appropriate compression level based on their server capacity and client expectations for optimal performance. Misconfigured compression levels may lead to either excessive bandwidth consumption or subpar media quality, making an understanding of the application's needs critical.
Furthermore, it is recommended to test different compression levels under actual operating conditions to find the most effective setting since the ideal compression may vary based on many factors such as the nature of the media content, the target audience's network capabilities, and available server resources.
Config Example
server {
location /live {
live_ksmp_comp_level 6;

}Setting the compression level too high may cause increased CPU usage on the server.
Conversely, setting the level too low may lead to increased bandwidth consumption and lower video quality.
