Here is the code I used for uploading an image.
$this->load->library('upload');
$ext = pathinfo($file_name, PATHINFO_EXTENSION);
$img_name = now() . "." . $ext;
$imgConfig['upload_path'] = $this->image_path;
$imgConfig['file_name'] = $img_name;
$imgConfig['max_size'] = '2048';
$imgConfig['allowed_types'] = 'jpg|png|bmp';
$imgConfig['overwrite'] = FALSE;
$this->upload->initialize($imgConfig);
if ($this->upload->do_upload("image_url")) {
$this->Playlist_model->update_playlist($insert_id, array("image_url" => $img_name));
}
And the frontend is simply a
<input type = 'file' >
The problem is , as the image upload should be an video thumbnail, what should I do to implement the upload? e.g using plugin in frontend to restrict/ crop (any recommendation)
Also, in server side how can I check?

$data_upload = $this->upload->data();
$file_name = $data_upload["file_name"];
$file_name_thumb = $data_upload['raw_name'].'_thumb' . $data_upload['file_ext'];
$this->load->library('image_lib');
$config_resize['image_library'] = 'gd2';
$config_resize['create_thumb'] = TRUE;
$config_resize['maintain_ratio'] = TRUE;
$config_resize['master_dim'] = 'height';//Check link 1 below
$config_resize['quality'] = "100%";
$config_resize['source_image'] = './' . $user_upload_path . $file_name;
//for 16:9 width is 640 and height is 360(Check link 2 below)
$config_resize['height'] = 360;
$config_resize['width'] = 640;
$this->image_lib->initialize($config_resize);
$this->image_lib->resize();
$data["file_name_url"] = base_url() . $user_upload_path . $file_name;
$data["file_name_thumb_url"] = base_url() . $user_upload_path . $file_name_thumb;
Notes:
do_upload function: save uploaded file to web server, resize the file and display result.
