Mark Donnigan is Vice President of Marketing for Beamr, a high-performance video encoding innovation company.
Computer software application is the bedrock of every function and department in the business; appropriately, software application video encoding is necessary to video streaming service operations. It's possible to enhance a video codec application and video encoder for two but seldom 3 of the pillars. It does state that to deliver the quality of video experience customers expect, video suppliers will need to examine industrial solutions that have actually been performance optimized for high core counts and multi-threaded processors such as those available from AMD and Intel.
With so much upheaval in the distribution design and go-to-market service plans for streaming home entertainment video services, it may be tempting to push down the top priority stack choice of new, more effective software video encoders. With software application eating the video encoding function, calculate efficiency is now the oxygen required to thrive and win versus a progressively competitive and congested direct-to-consumer (D2C) market.
How Video Encoder Computing Efficiency Can Impact Streaming Service Quality
Up until public clouds and common computing turned software-based video operations mainstream, the procedure of video encoding was carried out with purpose-built hardware.
And then, software application consumed the hardware ...
Marc Andreessen, the co-founder of Netscape and a16z the renowned endeavor capital company with investments in Foursquare, Skype, Twitter, box, Lyft, Airbnb, and other similarly disruptive companies, penned an article for the Wall Street Journal in 2011 titled "Why Software Is Consuming The World." A variation of this post can be found on the a16z.com website here.
"Six decades into the computer revolution, four years since the innovation of the microprocessor, and twenty years into the rise of the modern Web, all of the technology needed to change industries through software lastly works and can be extensively delivered at worldwide scale." Marc Andreessen
In following with Marc Andreessen's prophecy, today, software-based video encoders have actually almost completely subsumed video encoding hardware. With software application applications freed from purpose-built hardware and able to operate on ubiquitous computing platforms like Intel and AMD based x86 machines, in the data-center and virtual environments, it is entirely accurate to say that "software application is consuming (or more appropriately, has eaten) the world."
However what does this mean for an innovation or video operations executive?
Computer system software is the bedrock of every function and department in the enterprise; appropriately, software video encoding is essential to video streaming service operations. Software video encoders can scale without requiring a direct boost in physical area and utilities, unlike hardware.
When handling software-based video encoding, the 3 pillars that every video encoding engineer should deal with are bitrate efficiency, quality conservation, and computing efficiency.
It's possible to enhance a video codec execution and video encoder for 2 but hardly ever 3 of the pillars. A lot of video encoding operations thus focus on quality and bitrate performance, leaving the calculate effectiveness vector open as a sort of wild card. As you will see, this is no longer a competitive method.
The next frontier is software application computing performance.
Bitrate efficiency with high video quality needs resource-intensive tools, which will lead to slow operational speed or a substantial increase in CPU overhead. For a live encoding application where the encoder must run at high speed to reach 60 frames-per-second (FPS), a compromise in bitrate efficiency or outright quality is typically needed.
Codec complexity, such as that required by HEVC, AV1, and the forthcoming VVC, is surpassing bitrate effectiveness advancements and this has produced the requirement for video encoder efficiency optimization. Put another method, speed matters. Typically, this is not a location that video encoding specialists and image researchers require to be interested in, however that is no longer the case.
Figure 1 illustrates the benefits of a software application encoding application, which, when all qualities are normalized, such as FPS and objective quality metrics, can do twice as much deal with the specific very same AWS EC2 C5.18 xlarge instance.
In this example, the open-source encoders x264 and x265 are compared to Beamr's AVC and HEVC encoders, Beamr 4, and Beamr 5.

For services needing to encode live 4Kp60, one can see that it is possible with Beamr 5 but not with x265. Beamr 5 set to the x264 equivalent 'ultrafast' mode can encode 4 individual streams on a single AWS EC2 C5.18 xlarge circumstances while x265 operating in 'ultrafast' can not reach 60 FPS at 4K. As you can see in this poignant example, codec efficiency is straight related to the quality of service as an outcome of less makers and less complex encoding structures needed.
For those services who are mainly worried with VOD and H. 264, the best half of the Figure 1 graphic shows the performance advantage of a performance enhanced codec application that is set up to produce really high quality with a high bitrate performance. Here one can see as much as a 2x benefit with Beamr 4 compared to x264.
Video encoding compute resources cost real cash.
OPEX is thought about thoroughly by every video distributor. Expect home entertainment experiences like live 4K streaming can not be delivered reliably as a result of an inequality between the video operations ability and the expectation of the consumer.
Due to the fact that of efficiency limitations with how the open-source encoder x265 uses calculate cores, it is not possible to encode a live 4Kp60 video stream on a single machine. This doesn't imply that live 4K encoding in software isn't possible. It does state that to deliver the quality of video experience consumers expect, video suppliers will need to assess commercial services that have actually been performance optimized for high core counts and multi-threaded processors such as those offered from AMD and Intel.
The requirement for software to be optimized for greater core counts was just recently highlighted by AMD CTO Mark Papermaster in an interview with Tom's Hardware.
Video distributors wishing to utilize software for the flexibility and virtualization options they provide will encounter excessively made complex engineering difficulties unless they select encoding engines where multi-processor scaling is native to the architecture of the software encoder.
Here is a short article that reveals the speed benefit of Beamr 5 over x265.
Things to believe about concerning computing performance and performance:
It's tempting to believe this is just an issue for video streamers with tens or hundreds of millions of subscribers, the very same trade-off factors to consider should be considered regardless of the size of your operations. While a 30% cost savings at 1080p (H. 264), which is encoded at 3.5 Mbps, will provide more than triple the return, at a 1 Mbps savings. The point is, we should carefully and methodically consider where we are investing our compute resources to get the maximum ROI possible.
An industrial software application service will be constructed by a devoted codec engineering group that can stabilize the requirements of bitrate performance, quality, and compute performance. Precisely why the architecture of x264 and x265 can not scale.
Insist internal groups and specialists perform calculate efficiency benchmarking on all software encoding solutions under consideration. The 3 vectors to measure are absolute speed (FPS), specific stream density when FPS is held consistent, and the overall number of channels that can be produced on a single server utilizing a nominal ABR stack such as 4K, 1080p, 720p, 480p, and 360p. All encoders should produce equivalent video quality throughout all tests.
The next time your technical team plans a video encoder shoot out, make certain to ask what their test strategy is for benchmarking the compute performance (performance) of each solution. With so much upheaval in the circulation model and go-to-market service prepare for streaming entertainment video services, it might be Mark Donnigan appealing to lower the top priority stack selection of brand-new, more efficient software video encoders. Forfeiting this work might have a genuine impact on a service's competitiveness and ability to scale to fulfill future home entertainment service requirements. With software eating the video encoding function, compute efficiency is now the oxygen required to grow and win versus a significantly competitive and congested direct-to-consumer (D2C) market.
