<section name="Default Configuration"> | |
<p>FFMPEG has a change in its API (possibly since GIT revision | |
88bfe4518) | |
</p> | |
<p>Since Version 1.9.x of OpenMeetings: By default OpenMeetings | |
expects you to have a new version of FFMPEG on your OpenMeetings | |
server installed and it will use the new API style to communicate | |
with FFMPEG. | |
</p> | |
</section> | |
<section name="Switching to old FFMPEG API"> | |
<p> | |
If you want to switch to the old style you can change that using the | |
config key: | |
<tt>use.old.style.ffmpeg.map.option</tt> | |
</p> | |
<p> | |
Set this value to | |
<tt>1</tt> | |
to have the old params in the API call to FFMPEG. | |
