How to reduce post processing of recorded file in room ?

[KaranBhansali91]

Hi,


We are using mixer to create room session(one participant) with recording enabled , after end of room session , multi-recorder___dummy.mp4 generates the multi-recorder___dummy_mixed.mp4 , however flashphoner is taking too much time to generate the mixed file. For example 30 minutes recording, it will take another 10 minutes to generate multi-recorder___dummy_mixed.mp4 file.

Is there any property to enable?
Please provide us some solution to reduce this post processing time.

Good day.

2 cpu cores and 4gb RAM

That's the bottleneck. One mixer requires 2 CPU cores (with default settings), so you should use at least 8 CPU / 16 Gb RAM.

Hi,
We updated the configuration 8 CPU and 16Gb RAM. Please check the screenshot below. Recording duration 15mins,it took almost 4 - 5 mins to generate mixed file

Try to enable Multithreaded encoding while mixing multiple stream recordings by adding to /usr/local/FlashphonerWebCallServer/conf/offline_mixer.json file the following parameter:

"multithreading": true

This should make encoding a twice faster.

Hi,
As per your suggestion, we added above suggested property in /usr/local/FlashphonerWebCallServer/conf/offline_mixer.json
{
"hasVideo": "true",
"hasAudio": "true",
"mixerDisplayStreamName": "true",
"multithreading": "true"
}
but it's giving below error:
Setting 'multithreading' is not found. Please check setting


As per your documentation this property added in 5.2.1089 (

Stream recording - Web Call Server 5.2 - EN - Flashphoner Documentation

docs.flashphoner.com

)
and we are using FlashphonerWebCallServer-5.2.1261

Please share the more details to enable this property
