MacOS desktop application that transcodes a queue of video files into an HLS streamable playlist consisting of video segments for the desired resolutions.

For the output destination selected, when the output id option is deselected each video's transcoded playlist will be placed inside a folder named after the file. When the output id option is selected, each video will be placed inside a folder named with a unique id. For each playlist, the resolution segments will be placed in a subfolder named for the resolution.

For example, if the video is called adonisjs-quick-tip.mp4 and the resolutions 2160p and 1080p are selected, the output will look as such:

.
└── [selected destination]/
    └── adonisjs-quick-tip/
        ├── 1080p/
        │   ├── adonisjs-quick-tip_1080_001.ts
        │   ├── adonisjs-quick-tip_1080_002.ts
        │   ├── adonisjs-quick-tip_1080_003.ts
        │   └── adonisjs-quick-tip_1080.m3u8
        ├── 2160p/
        │   ├── adonisjs-quick-tip_2160_001.ts
        │   ├── adonisjs-quick-tip_2160_002.ts
        │   ├── adonisjs-quick-tip_2160_003.ts
        │   └── adonisjs-quick-tip_2160.m3u8
        ├── video.mp4 [compressed original]
        ├── video.webp [6s animated webp]
        └── master.m3u8
