灵活的流媒体:经济高效的流媒体软件

Furtree系统, 是直播媒体服务器软件的领导者，最近主持了一项流媒体杂志调查 liverstream趋势，提供三个层次的 其获奖 Softvelum灵活流光.

The basic Nimble Streamer server provides two key elements that survey respondents ranked high in their key requirements: livestreaming/transmuxing and video-点播(VOD) features.

在扩大规模的同时控制成本

One of the key takeaways from the Furtree-sponsored 2023年直播技术趋势 survey was a growing concern around both capital expenses (CapEx) and operational expenses (OpEx) in an era of tightening budgets and rising delivery costs.

对于当前和潜在客户来说，好消息是基本的Nimble Streamer套装起价为70美元。. 这个基本包包括一个服务器实例以及对WMSPanel功能的访问, 一个管理平台，帮助客户管理多个灵活的Streamer实例.

灵活的Streamer的内置转换-重新包装流媒体内容从一个协议到另一个的能力, without changing the underlying content—Nimble Streamer customers can leverage the core engine to ingest in one protocol and output streams via other selected protocols while avoiding additional processing overhead.

添加另一个服务器许可证每个服务器每月只需花费50美元, 允许灵活的流媒体客户扩大和缩小与他们的流媒体需求的灵活性.

两个额外的许可证, 每个服务器许可证每月50美元, 圆我们的灵活Streamer用户的关键组所需要的额外功能. 其中之一是转码许可, 哪个提供各种行业编解码器之间的即时转码, 而额外的附录许可提供数字版权管理(DRM)。, 服务器端广告插入(SSAI), 和先进的SRT功能和更多.

服务器实例在客户的硬件上运行, 他们是否选择基于云服务的服务器实例，如亚马逊网络服务(AWS)或Azure, 或者本地裸机服务器. 一些客户选择硬件转码加速, with Nimble Streamer’s Transcoding license supporting both Intel Quick Sync Video and Nvidia GPU transcoding hardware and software support.

从性能的角度来看, Nimble Streamer has enough built-in robustness that we’re comfortable claiming that customers can perform high-load delivery to a large number of viewers on anything from cloud-based server instances to their own bare metal servers. 我们的重点是降低百家乐软件的使用，以准备和交付流, we’re also comfortable claiming that you’ll likely run out of bandwidth before you hit hardware resources limits or any limitations of the Nimble Streamer software.

远程捐款处理

Another key finding in the 2023年直播技术趋势 survey was the widespread use of a surprising number of acquisition and delivery protocols. Nimble Streamer涵盖了所有这些方面，包括传统和新兴协议. 我们不仅提供了古老的RTMP和RTSP协议, 在推和拉配置, 以及传输流协议——包括基于http的DASH, HLS和MPEG-2 TS或基于udp的MPEG-2 TS -但我们也涵盖了新兴的协议，如SRT, 抗利尿, 和WebRTC鞭子摄入.

使用较新的传输解决方案，如ndi(以广播为中心的传输协议), which in integrated into everything from cameras to graphics workstations to vision mixers—and the audio-based DANTE protocol from Audinate supported, Nimble Streamer can be integrated into professional live-production workflows that require both legacy and emerging protocols.

强大的转码选项

虽然目前绝大多数通过流媒体服务器传输的内容都使用H.264 (AVC或MPEG-4 part 10)或H.265 (HEVC)视频编解码器, 从设备获取实时流, 电脑, 或者甚至是集成了流输出的相机——可能源自近12种编解码器中的一种.

This includes legacy industry-standard codecs (MPEG-2 and MPEG-4 part 2) and proprietary codecs such as VP8 or VP9, 以及崭露头角的AV1编解码器, all of which were mentioned by respondents to the 2023年直播技术趋势 survey as key to their video compression workflows.

灵活的Streamer可以转换这些不同的编解码器与它的转码许可, 允许将任何这些编解码器转换为交付就绪的H.264或H.265. 我们优化了百家乐软件的使用, 与任何竞争的流服务器产品相比，具有更多的摄取流转码性能.

不仅仅是视频编解码器可以被转换. 灵活的流媒体可以摄取超过六种音频编解码器，包括AAC, G.711, MP3, MP2, Opus和spex -并转码到AAC或MP3的传输流. The fact that Nimble Streamer handles both open-source (Opus) and legacy video- or voice-over-IP audio codecs means that you’re covered for whatever ingest streams you need to transcode to reach a wider audience.

在性能方面，我们还在许多关键方面优化了Transcoder. 例如, using the WMSPanel web user interface provides Nimble Streamer customers with an easy-to-use drag-and-drop workflow through which a customized transcoding scenario can be easily applied across various servers.

除了, because Transcoder’s built-in logic guarantees that decoding of the initial stream—and subsequent re-encoding into either AVC or HEVC—are done just once per frame, 在转码到多个编解码器时，避免了不必要的处理开销，从而提高了性能. 对于那些在英伟达图形处理器(gpu)上投入巨资的人来说，

灵活的Streamer允许NVENC完全处理管道，而无需额外的软件处理.

高级快速选项

With a growing interest in free ad-supported television (FAST) business models—as a way to offset subscriber declines or just to supplement revenues with an advertising stream—Nimble Streamer offers advanced 服务器端广告插入(SSAI) against which one can apply business logic (as simple or complex as needed to choose which ads to show based on time of day, 地理位置, 按次计费的, 等.).

SSAI特性可以很容易地实现, without even needing to install anything on the server; just add a configuration file and enable the Addenda license. 输出选项很多, from traditional Icecast and RTMP to HTTP-based (HLS) as well as Nimble Stream’s proprietary low latency SLDP output protocol.

Ads can be placed at the beginning or end of a video stream (pre-roll or post-roll) or anywhere in between (interstitial or mid-roll ads). 增强了Nimble Streamer提供的基本业务逻辑, 附录许可允许Nimble Streamer识别SCTE35标记, 提供高级插入和直通选项.

保护内容(DRM和Paywall)

当灵活的流客户需要保护他们的直播流, 点播(VOD), 和数字视频录像机(DVR)内容, 基本功能是内置的, 包括地理围墙, to limit viewership in a specific region; geoblocking to keep rogue viewers out; and IP filtering.

此外，灵活的流光是标准的. HLS的AES-128加密, as well as SSL protection for DASH and HLS and the ability to link to third-party paywall authentication providers.

对于那些需要更多内容保护的人, the Addenda license provides the ability to tie into third-party digital rights management (DRM) solutions across a wide spectrum of providers.

内置VOD和DVR选项

而几乎所有的灵活流客户使用我们强大的服务器提供直播流, a growing number of customers also use Nimble Streamer’s built-in video-点播(VOD) functionality to deliver even more benefit to their own customers.

For those who want to offer DVR functionality for live streams—allowing viewers to catch up on a live stream at their own pace or perform their own instant replays of a key event—Nimble Streamer has that covered, 太, 作为其基本功能的一部分.

但是等等，还有更多!

灵活的流光的所有好处, 我们甚至还没有触及Softvelum移动广播工具.

例如, the Larix Broadcaster app for iOS and Android turns your mobile device into a full-scale camera with advanced connectivity capabilities for reliable remote contribution. 访问 softvelum.com/larix 以了解更多关于Larix播音员的功能，并查看最值得注意的用例示例.

底线

当谈到《百家乐app下载》时，底线是:我们的团队以创造高效率而自豪, low-resource-optimized streaming solutions that are cost-effective solutions for both sets of our traditional customers (small streaming startups and large broadcasters) that need added flexibility to scale on a server-by-server basis.

我们会有更多关于 2023年直播技术趋势 接下来的几个月, but here’s a key takeaway for our customers and potential customers: you can scale at your own pace with Nimble Streamer.

不管你是否有兴趣使用一个或几十个灵活的Streamer实例, our WMSPanel cloud control system allows you to deploy robust business logic and workflows across every Nimble Streamer license, 不强迫你购买额外的功能，直到你真的需要它们. 这是你可以用来在不确定时期发展业务的储蓄. 访问 softvelum.com/nimble 以获得更多关于灵活的Streamer和其他Softvelum解决方案的信息.
