Can't get FFMPEG to process videos

I am having trouble with videos processing. The encoding gets stuck at zero no matter what I do and how far I search.
I have been in contact numerous times with my server. They have given me the best ffmpeg they can, which should be the v.2.8.x ffmpeg.

This is the information they gave me;

This static ffmpeg version is linked to the previous filepath we had sent you:
/usr/local/bin/ffmpeg-new

Here is the full output for this specific ffmpeg version:
# /opt/icert/bin/ffmpeg-new -version

libswresample 3. 2.100 / 3. 2.100
libpostproc 55. 2.100 / 55. 2.100

Any help would be so very much appreciated! =)
Thank you guys!
It seems like your FFmpeg return this following log message when encoding the video :

Currently i have no ideas why it shown these error yet, It might be the most FFmpeg version is not compatible with Easysocial, perhaps you can request with your webhosting provider to re-check again whether that is possible to install FFmpeg 2.8.x version ? Because different of FFmpeg version, it might be those command syntax also different.

I forwarded this to them asking them to take a look and possibly install the 2.8.x version.

They will be poking around the admin as well.

"Where you are configuring the specific video conversion scripts and modules." -server

I gave them these paths. Are there more they should look at?
/home/elevent1/public_html/media/com_easysocial/videos/
/home/elevent1/public_html/components/com_easysocial/controllers/videos.php

I will keep you updated if they find something.

Thank you guys for all the help!

Hi guys,

Well my server got back with me... there next 2 versions they both return NULL...
I have also disabled everything i use from techjoomla. every com, plg and mod... Still nothing =/

**From Server
We have added FFMPEG 2.8.14 to your account. The path is:
/home/elevent1/bin/ffmpeg2.8.14 =ENCODING NULL%

There is also FFPROBE available:
/home/elevent1/bin/ffprobe2.8.14 =ENCODING NULL%

/opt/icert/bin/ffmpeg-new =ENCODING 0%


Not sure what is going on here lol

Hey there,

I am really sorry for the delay of this reply as it is a public holiday for us here.

Thanks for getting back to us, it seems like your FFmpeg return this error which is better than before

Based on what i read those forum post who having the same issue with this, it seems like you doesn't install/compile this libx264 library into your FFmpeg, 2.8.14 can you try read this following Compilation Guide if it help much you here? Or you can just pass to your webhosting provider who handle your case regarding this.

https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

Keep us updated then.
