Answer 1

You're encoding your array to JSON, so at some point you need to decode it again into a PHP array. Since you actually have several JSON objects in the file, you need to decode each one individually. Assuming it's always one JSON object per line, this'll do:
$jsonObjects = file('overlay.txt', FILE_IGNORE_NEW_LINES);
foreach ($jsonObjects as $json) {
$array = json_decode($json, true);
echo $array['title'];
...
}
This will very quickly break if there are line breaks within the serialized JSON, e.g.:
{"title":"ret54","description":"foo
bar","code":"ty76"}
That way of storing the data is not very reliable.

Answer 2

make overlay.txt fully json format:
[
{"title":"sss","description":"sss","code":"sss"},
{"title":"trtr","description":"trtr","code":"tyrytr"},
...
]
and try this:
$raw = file_get_contents('./videos/overlay.txt', true);
$this->load->view('includes/overlays', array("filecon" => json_decode($raw)));
overlay page:
<?php
foreach($filecon as $files) {
echo $files['title'];
}
?>
If you want to use $filecon in view file,
set an array which has the key "filecon" in $this->load->view()'s second argument.
