FreeSWITCH call recording not working

Question

I am trying to implement conference video call recording in FreeSWITCH using mod_fsv. I have tried all the methods mentioned here. But each time I get the following error

[ERR] mod_fsv.c:964 You are asking to write 16384 bytes of data which is not supported. Please set enable_file_write_buffering=false to use .fsv format

I have tried setting enable_file_write_buffering using uuid_setvar, global_setvar and <action application="set" data="enable_file_write_buffering=false"/> in the dialplan but the error still persists.

I am using the latest FreeSWITCH master repo code.

Any help or suggestions will be appreciated. Thank you!

Found the solution finally!

Enable mod_vlc in your FreeSWITCH modules.conf and compile. After this in your dialplan default.xml add the following lines:

<action application="set" data="record_concat_video=true"/>
<action application="set" data="execute_on_answer=record_session $${recordings_dir}/${strftime(%Y%m%d%H%M%S)}_${caller_id_number}.mp4"/>

The record_concat_video variable is required to ensure the calling parties see each others video.

There is an open issue in mod_vlc regarding audio in the video recording. Currently either no audio or partial audio is recorded. Once this issue is fixed the same settings can work perfectly.
