What Is the Relationship Between VOD and OBS?
The relationship between VOD and Object Storage Service (OBS) is as follows:
- VOD is an all-in-one media service that integrates upload, storage, transcoding, processing, distribution, and playback. OBS is an object-based storage service that provides massive, secure, highly reliable, and cost-effective data storage. VOD stores input media files and output media files such as subtitles and snapshots. OBS can store multiple types of files, such as audio and video files, images, and texts. Its functions are similar to those of a cloud disk.
- OBS can work with CDN to accelerate delivery of files stored in OBS buckets. To use the VOD service, you need to add licensed domain names to the VOD service for media file distribution acceleration. In addition, VOD provides functions such as transcoding, audio extraction, video editing, and video review. Compared with OBS, VOD can better meet your requirements for online videos.
- Media files in VOD are stored in an OBS bucket. However, the OBS bucket is invisible and those media files do not occupy any OBS space. You do not need to enable OBS.
