MG 1.1 Problem Transcoding

#1
I have transcode enabled so that members can post avi, 3gp but I get the error message
Unfortunately, the video file you uploaded named VIDEO NAME could not be processed. Please upload a different video and try again.

If it’s not working on any videos then there could be a problem but if it’s just one or two then it could just be a problem with the video itself.

If you go to Admin CP > Applications > Gallery Options and then click "Save Changes" do you get any errors reported related to FFmpeg?

Also are there any server error logs in the Admin CP related to this?
 
#5
No but heres the error log I get
Here's the server Error Log

Ok.

We need to see what FFmpeg is actually saying about these videos so ideally you need to manually upload the video to your server (via FTP or similar). Uploading it to your XF web root might be easier (e.g. /var/www/vhosts/domain/httpdocs where domain is your domain name).

Then you need to cd into that directory.

Then you need to get your FFmpeg binary path out of your options, e.g. /usr/bin/ffmpeg (or whatever it might be).

Then you need to run the following command:
Code:
/path/to/ffmpeg -y -i <video.extension> -vcodec libx264 -acodec aac -ar 48000 -ac 2 -movflags faststart transcoded.mp4
Obviously you'll have to replace <video.extension> with the actual file name of the video you want to transcode.

Try and copy and paste the full output here if possible.

I had a 50% chance of guessing which audio codec you had...

Try:
Code:
/usr/bin/ffmpeg -y -i 02-02-11_2017.3gp -vcodec libx264 -acodec libvo_aacenc -ar 48000 -ac 2 -movflags faststart transcoded.mp4

Right... That's likely the problem, then... Though I wasn't necessarily aware there could be situations where neither of the codecs we support are available.
Code:
/usr/bin/ffmpeg -y -i 02-02-11_2017.3gp -vcodec libx264 -acodec aac -strict -2 -ar 48000 -ac 2 -movflags faststart transcoded.mp4
That seems like it would work.
