kmp_rtmp_out_buffer_bin_count
The `kmp_rtmp_out_buffer_bin_count` directive controls the number of binary data buffers used for RTMP output in Kaltura's media framework.
Description
The kmp_rtmp_out_buffer_bin_count directive specifies the number of binary data buffers that should be allocated for RTMP output streams. This setting is crucial for managing the streaming performance of live video content, as it directly influences the buffering behavior of the Kaltura Media Framework (KMP). Each buffer is used to hold chunks of data being sent out to clients, and the count parameter indicates how many such buffers should be maintained simultaneously.
By fine-tuning this directive based on your server's capabilities and the expected load, administrators can optimize the performance of video streaming. Increasing the count of buffers allows for more concurrent streaming sessions, but it also consumes more memory resources. Conversely, reducing the buffer count may lead to insufficient buffering in high-load scenarios, potentially resulting in choppy streams or increased latency.
In practice, analyzing your server performance and the audience size can help determine the most effective buffer count. It's advisable to start with the default value and make adjustments based on empirical performance metrics, observing how changes affect the quality and reliability of the live streams.
Config Example
stream {
server {
kmp_rtmp_out_buffer_bin_count 5;
}
}Setting the value too low may lead to dropped frames during high traffic periods.
A very high value can consume significant memory, which may affect overall server performance.
