Good luck!

I am getting the same problem, but slightly different error..........
please help!
No thumbnails are generated, making the video link look ugly (it is a reel).

I have mediainfo installed in this path
/home/rajivm/mediainfo

Do I have to edit line 32 in this file to this?

/home/rajivm/public_html/photos/plugins/piwigo-videojs/admin/admin_sync.php

'mediainfo' => '/home/rajivm/mediainfo',

[rajdude]

By the way, as per the instructions here:
https://github.com/Piwigo/piwigo-videojs/wiki/Using-MediaInfo%2C-ffmpeg-without-installing-it-inside-the-hosting-system

I have already modified this file
'piwigo-videojs/include/admin/admin_photo.php'
line 64

PS: I see an option to put the path of mediainfo on the tab VideoJS plugin [Synchronize]
...but it does not take it....throws the same line 53 error at the top of the browser page.

I have even removed the path from the two files, hoping that the config page will start working, I mean I was hoping that it will take the path....but no-go there also :-(

PLEASE HELP ! :-)

I had the same error, and did some digging to find a solution.
The first error is the one at line 53 of admin_sync.php, and that then repeats on line 78. Each time it is about array errors.

There are 2 separate problems that cause this. Firstly, the code in admin_sync.php is wrong, I fear. The aim of the code section between line 30 and 82 is to determine the sync options. They are derived in 3 layers: first the defaults (line 32-47), then the values from the persistent database (using the vjs_sync conf), and finally the user specified overrides from the URL request (line 59-74). On line 53 the first merge occurs (defaults + DB values) which then gets stored in the $sync_options variable. Note that this merge is conditional on the existence of any DB values. Therefore, on line 78, one should do the next merge. It is, but instead of using the previous merge result, the code refers to the DB values via the $conf of vjs_sync. That implies that, when no DB values exist, the merge will fail (not on line 53, but on line 78). This leads to a bad variable $sync_options, which is then written to the database. Any subsequent run will read that faulty DB config entry and fail again, this time on line 53 and on line 78.
Note that no errors will occur if you have a valid DB entry for vjs_sync. It will get updated and saved at each run.

So a first correction is this: Change line 78 of admin_sync.php to read like this.
$sync_options = array_merge($sync_options, $sync_options_form);
This ensures the correct merge occurs, and if no vjs_sync values exist, the defaults will be used.

But that alone is not enough: The merge on line 53 will still fail as the DB value is not OK. Hence, use phpMyAdmin to go to table piwigo_config, and look for the record with vjs_sync. Most likely, it will not be correctly formatted. A nicely formatted value starts with "a:3:{s:9:"some text"..." (the numbers can be different. See the php serialize function for details). If your entry looks like this, all should be fine. if it is not (mine contained an uppercase N and a few other symbols), simply delete the vjs_sync record. With the above code change, you will get the defaults to start with.
Now go bach to your videoJS Synchronize page, and you should get it working. Note that missing binaries will generate warnings, but that won't stop you from using this Synchronize (assuming you have at least one of the tools installed).

I hope this helps!
