MG 1.1 Video could not be processed error


Well-known member
I keep getting this message when i upload videos.

Unfortunately, the video file you uploaded named My Car Video could not be processed. Please upload a different video and try again.

It was working last month. Im not sure exactly when it stopped worked. What could be the problem. I tried 2 different videos and 2 different file types.

I remember installing ffmpeg a while ago and it was working.

Do i need to upgrade? or re-install?

I am running the latest versions

Generally, if you go to Gallery Options > Video Options and the options to transcode are all enabled (FFmpeg binary path and PHP binary path need to be filled in and correct, too) and you click save, you will get errors if anything isn't set up correctly.

If you don't get any errors and it still doesn't work, try and send me one of the videos, if possible.
i didn't get any errors after saving, i also tried an .mp4 and it uploaded fine,

I've had problems with .mpg, .avi, & 1 .flv file but another flv video worked fine

These are my settings,


Here is my ffmpeg info


Here is one of the videos i tried to upload, .wmv file(2.49MB)

here is an .flv video that won't work (bars and tone)

here is an .avi video that uploads and plays but the thumbnail doesn't work (drop & flame)

Also i want to note, something i found out tonight

In the media gallery on xenforo here it says under allowed extensions:


I tried to upload:

and i got this message


I was only able to successfully upload mp4 & m4v here on

And as you can see the thumbnails did not work.


So i believe it's not only my server,

Here are the 7 video files i used,

FFmpeg was somewhat recently disabled here, so that's not particularly surprising -- without it, only one format is supported. I'll need to re-enable it.

This also works but it didn't generate a thumbnail -- that's not a massive concern, though.

Works fine.

Here are the 7 video files i used,
All 7 worked fine (2 didn't require transcoding).

I would try a different FFmpeg version, and look at what changes you have made since it last worked. Something will have changed on the server to trigger this to stop working.
I guess the problem was my ffmpeg.

1. I didn't install it right or;
2. my ffmpeg version was old or corrupt

i will never know..

I ended up searching online and finding an Free FFMPEG autoinstaller.

Here's the website:

I used putty and following these instructions:

mkdir ~/ffmpeg-packages
cd ~/ffmpeg-packages
tar -xvzf ffmpeginstaller.8.0.tar.gz
cd ffmpeginstaller.8.0

it was so easy!

This autoinstaller not only installed ffmpeg, but installed a bunch of other things, not sure if i needed them...


but oh well.. there's no option to only install ffmpeg

anyways.. ffmpeg now works!

After installing that, and restarting my server,

I tried those 7 videos and...

All 7 uploaded fine and playback is fine

3 of them(AVI, MP4, OGG) the thumbnails didn't work

i really hate ffmpeg.. i'm not skilled enough to install it.. other then using an autoinstaller

i dont like using the terminal because im not good with it yet,

if someone isn't skilled, you can always try that autoinstaller,

it worked for me
