kmp_rtmp_in_buffer_size
Configures the input buffer size for RTMP streams in Kaltura Media Framework.
Description
The kmp_rtmp_in_buffer_size directive sets the maximum size of the input buffer for RTMP streams received by the Kaltura Media Framework. The value specified allows NGINX to temporarily hold incoming data from RTMP clients, thereby managing stream data effectively and preventing data loss or overflow during high traffic circumstances. This setting is particularly crucial in live streaming applications where real-time data processing and buffering are paramount to smooth delivery.
The buffer size specified by this directive is important because it directly correlates with the server's ability to handle large streams without dropping significant data packets. If the incoming stream data exceeds the size of this buffer, the server may experience delays or drops in streams, leading to a poor user experience. Therefore, administrators should configure this value based on their expected stream quality and server capabilities, taking into account factors like network bandwidth, server load, and the overall streaming infrastructure.
It is essential to remember that a higher buffer size may not always lead to better performance and can result in increased memory usage. Thus, it is advisable to balance the buffer size according to the anticipated load and available resources on the server.
Config Example
stream {
server {
listen 1935;
kmp_rtmp_in_buffer_size 2m;
}
}Setting the buffer size too low may lead to dropped packets during high network usage.
Excessively high buffer sizes can increase memory consumption and potentially impact other running services.
