Download the PHP package ivebe/lffmpeg without Composer

LFFMPEG

PHP-FFMpeg implementation in Laravel with progress bar. Plug and play.

Installation

Install using composer.

After you install it add service provider to the providers array in the config/app.php

Publishing at least config from the vendor is required, this is tagged as defaults. Available tags are migrations, models, assets, views and defaults. If you are building from scratch you can just ommit tag completely and publish everything. However if you already have system in place, and want to adopt it to use Lffmpeg, then publish defaults (config) only, and add current models implementation in the config file.

Config

This is where encoding settings are placed, and also models that will handle the logic. Lffmpeg already have 3 eloquent models for Video, Thumb, and EncodingProgress

Paths

Paths should not end with slash.

• paths#tmp_path path on disk to the temporary directory. This is where you should upload your video file.
• paths#content_path path on disk where encoded videos and thumbs will be placed

FFmpeg

Location of the ffmpeg binaries.

• encoding#ffmpeg_binaries absolute path to the ffmpeg binary
• encoding#ffprobe_binaries absolute path to the ffprobe binary
• encoding#threads number of threads to use for encoding

Encoding

Desired profile used for encoding. Lffmpeg will automatically detect best possibile quality and encode from it. In other words if you have video that is not HD, then 1080p profile wont be encoded, it will start from the best match profile. There is no upscalling.

• encoding array of encoding profiles. Example:

Video model

Videos are manipulated using VideoRepository. By default there is only Eloquent repository, so you need to set video model in the config file. If you are already having your video model, then just point proper column names and your model will be used instead. Note that variables are marked with # while colum names are marked with @.

• video#model Class that represent video model. (Ex. \App\Video::class)
• video@duration Name of the duration column
• video@status Name of the status column
• video@default_thumb Name of the default_thumb column

Thumb model

Thumbs are manipulated using ThumbRepository. By default there is only Eloquent repository, so you need to set thumb model in the config file. If you are already having your thumb model, then just point proper column names and your model will be used instead. Note that variables are marked with # while colum names are marked with @.

• thumb#model Class that represent thumb model. (Ex. \App\Thumb::class)
• thumb#interval Number of seconds between which thumbs are taken.
• thumb#name-format sprintf string where only parameter is number of image (Ex. thumb_%s.jpg)
• thumb#width desired width of a thumb
• thumb#height desired height of a thumb
• thumb@video_id name of foreign key video_id
• thumb@name column name
• thumb@scene_time column scene_time

EncodingProgress model

EncodingProgress doesn't have it's own repository, it is manipulated using VideoRepository. By default there is only Eloquent repository, so you need to set EncodingProgress model in the config file. If you are already having your EncodingProgress model, then just point proper column names and your model will be used instead. Note that variables are marked with # while colum names are marked with @.

• progress#model Class that represent EncodingProgress model (Ex. \App\EncodingProgress::class)
• progress@video_id name of foreign key video_id
• progress@quality name of the quality column
• progress@status name of teh status column
• progress@percent name of the percent column

Usage

Basic usage is as simple as typing Helper::runEncoding(123); where 123 is video ID in the Video repository. However you should know that each encoding process is done using jobs and queues, so you should setup your queue properly.

Publishing vendor files

Available tags are migrations, models, assets, views and defaults.

• migrations if you wish to use pre-made models, publish migrations and run php artisan migrate
• models running php artisan vendor:publish --tag=models will place Video, Thumb and EncodingProgress models in the app directory.
• assets this will publish js file to the public/assets/lffmpeg.js which will have simple js written to handle display of the progress bar. You can see sample of it's usage if you publish views also.
• views publish example view file to the resources/views/lffmpeg.blade.php
• defaults publish config file.
