Nullsoft Streaming Video (NSV) was a media container designed for streaming video content over the Internet. NSV was developed by Nullsoft, the makers of Winamp.
The NSV format is another example of streaming video formats, offered by various companies and media players. Windows Media, QuickTime File Format and RealMedia streams are just a few examples of these, and each have their benefits and shortcomings. NSV, by default configuration, used MP3 as its standard audio format, with VP3 as the video format. Various hacks and codec installations allowed NSV to use Ogg Vorbis for audio and later updates of the VP codecs for video.
One of the shortfalls of most streaming formats often comes from the difficulty in finding streams, or at least some form of directory service; and in some cases, none are readily available to the public at all. With Nullsoft's SHOUTcast service, a media streaming and directory system, the NSV format became popular, along with SHOUTcast's listings of Streaming Audio, which reach well into the thousands. The 'Media Library' offers integrated listings of both audio and video streams, returned directly from the SHOUTcast service.
With Nullsoft's sale to Radionomy in 2014, NSV is no longer supported.
The freeware player VLC can be used to convert NSV files into standard video and audio formats like mp4 or mp3.
History[edit]
NSV was created in late 2002/early 2003 by Justin Frankel while working at Nullsoft.Originally designed as a demonstration of the potential that newly developed streaming technology Ultravox could offer, it later became an accepted format for AOL streaming media, with many promotional videos available on both Winamp.com and the AOL website.
Players[edit]
Current media players that support the Nullsoft Video format are:
- GoodPlayer for iOS
- MoboPlayer for Android
- RealPlayer Plug-In - http://rnsv.hit.bg[citation needed]
- RockPlayer 1.x for Android (not RockPlayer2)
- VLC (with VP6 support since 0.8.6, can also convert)

Organizations around the world choose Backblaze to solve for their use cases while improving their cloud OpEx vs. Amazon S3 and others. Backup & Archive. Store securely to the cloud including safeguarding. Data on VMs, servers, NAS, and computers. Content Delivery. NextCloud & BackBlaze B2 secure backup script / howto I wanted to share my backup script with everyone. This is a script that syncs to Backblaze B2 all of your files (encrypted by NextCloud), all of your encryption keys (enclosed in a tarball encrypted by a separate GPG key) and SQL dumps (also encrypted with that GPG key). 
It is like a translation layer that allows you to access your backblaze b2 account (or any other supported type of cloud storage) using the Amazon S3 API. Then I configured nextcloud to use the Amazon S3 storage driver instead of the local file disk. NextCloud, an enterprise file sync & share (EFSS) frontend for a variety of storage backends, can be configured to use S3 as primary storage. Normally NextCloud relies on conventional storage such as block volumes and RAID arrays that need to be scaled using tools such as LVM as the volume of data stored on the deployment grows.
