kmp_rtmp_out_notif_buffer_size
Sets the buffer size for RTMP notification messages in Kaltura Media Framework.
Description
The kmp_rtmp_out_notif_buffer_size directive specifies the size of the buffer used for sending RTMP notifications from Kaltura Media Framework. In the context of live video streaming, RTMP (Real-Time Messaging Protocol) is an essential protocol for transmission of audio, video, and data over the Internet. By adjusting this buffer size, you can optimize the performance of notification delivery in scenarios involving live streaming, which may improve responsiveness and reduce latency. The buffer is crucial for accommodating bursts in notification traffic, ensuring that messages are delivered without loss during high-load periods.
The directive takes a single parameter, which represents the size of the buffer in bytes. A larger buffer might provide more stability under heavy load conditions but could introduce latency, whereas a smaller buffer can reduce latency but may risk message loss during spikes of traffic. Therefore, careful consideration of the buffer size is essential based on the expected notification volume and system capabilities, particularly in production environments where stream stability is mandatory. It's generally recommended to test various configurations under expected loads to determine the optimal size for your use case.
Config Example
stream {
kmp_rtmp_out_notif_buffer_size 64k;
# Additional stream configurations
}Buffer size should be chosen based on expected notification load; too small may cause message loss.
Make sure that the buffer size does not exceed system memory limits to avoid performance degradation.
Consider adjusting the buffer size in sync with other performance-related parameters in the streaming configuration.
