Will HEVC/H.265 Kill the Data Center?

Will HEVC/H.265 Kill the Data Center? | Video Breakthroughs | Scoop.it

QuickFire thinks so, which is why it's introducing the T-Video Transcoding Platform V1100, a single-RU box with multiple Ethernet connectors and 11 quad-core Core i7 mobile CPUs.

Nicolas Weil's insight:

Not a direct Elemental competitor yet - but a good thing for emulation on the GPU-assisted transcoding market.

The benefits of FPGAs

The benefits of FPGAs | Video Breakthroughs | Scoop.it

We are on the cusp of the next exciting age of video compression as High Efficiency Video Coding (HEVC) is expected to be standardized in early 2013. Due to the inherent flexibility of FPGA devices, equipment engineers and designers can get started now on next-generation equipment, and be assured that IP they develop should be adaptable to any possible, late-stage standards shifts.

 

The expected move to HEVC (H.265) follows a steady progression of video compression: the introduction of MPEG-1 in 1992 (which laid the foundation for the ensuing revolution in consumer digital video content), the release of MPEG-2 in 1994 (which offered compressed, broadcast-quality digital video) and H.264 in 2003 (which spurred worldwide HD digital video, Blu-ray, Internet streaming and mobile video).

WebM Gaining Momentum in Hardware

WebM Gaining Momentum in Hardware | Video Breakthroughs | Scoop.it

Hardware product cycles are very long, especially from the software developer’s perspective. However, in just under two years after the launch of the WebM Project, the leading chip vendors are bringing to the market full hardware support for VP8 real time and streaming video decoding and encoding at 1080p resolution.

 

In addition to the K3V2 application processor from Huawei and the RK30xx application processor from Rockchip announced at the Mobile World Congress 2012, ST-Ericsson has also finished developing a new platform with full VP8 support. “Working with the WebM team, ST-Ericsson is proud to demonstrate the first prototype devices using the NovaThor L954, a complete LTE platform for smartphones and tablets equipped with a high-performance application processor,” said Itai Dadon, Smartphone Business Development at ST-Ericsson. “The NovaThor L9540 incorporates a dual-core CPU, a powerful graphics engine and optimized multimedia accelerators in a high-performance, low-power solution which is fully geared for 1080p 30fps video playback of WebM on HTML5”.

Video Encoding: Go for the Specialist or the Jack-of-All-Trades?

Video Encoding: Go for the Specialist or the Jack-of-All-Trades? | Video Breakthroughs | Scoop.it

When it comes to video encoding, the choice between hardware and software comes down to flexibility, latency, and cost.

 

One of the hardest choices encoding technicians have to make is deciding between hardware and software. Hardware-based encoders and transcoders have had a performance advantage over software since computers were invented. That's because dedicated, limited-purpose processors are designed to run a specific algorithm, while the general-purpose processor that runs encoding software is designed to handle several functions. It's the specialist versus the jack-of-all-trades.

 

In the past few years, processors and workflows have changed. The great disruptor has been time and the economics of Moore's Law, which famously says that the number of transistors incorporated in a chip will approximately double every 24 months. The logical outcome of Moore's law is that the CPUs get more powerful by a factor of two every few years, but more recently processing power seems to double every few months. Lately, Intel -- whose co-founder Gordon Moore coined Moore's Law -- has been adding specialty functions along with its math co-processors to equalize the differences between general-use processors and specialty processors.

 

There are many layers and elements to both a general-purpose processor and a task-specific hardware processor. The general-purpose CPU is the most common -- there are literally billions of them in all manner of computing devices -- while the more purpose-oriented processors include digital signal processors (DSPs), field-programmable gate arrays (FPGAs), and integrated circuits (ICs) that are available for various industrial appliances and widely used in cellphones. Many of the structures and elements are similar across all types, but there are considerable differences. If you are not familiar with the elements of the various types, here are the basic structures of both.

Wowza Transcoder AddOn test report

Wowza Transcoder AddOn test report | Video Breakthroughs | Scoop.it

Following our latest review of the features of Wowza Media Server, let’s now look at how to transcode video streams using this plugin. This feature is helpful when you only have a single source of high quality video and you would like to deliver the video to multiple devices. Yet another example is video stream failback to audio only in an iOS application (AppStore’s requirement), where you need an additional stream with cut-off video. A typical approach to this problem requires a transcoder (you can also generate an audio only stream using the new Adobe Media Server 5.0). Usually, a transcoder is a separate server optimized for video handling. Wowza offers an alternative: transcoding at the media server level. Let’s look at how it works in more detail.

 

Wowza Transcoder is a paid addon to the Wowza Media Server. It can transcode incoming video to H.264 (MPEG-4) streams tailored for different viewing devices. To run a transcoder, please install a 64-bit version of Java. Wowza Media Server supports the hardware transcoder technologies: Intel Quick Sync hardware acceleration and Nvidia CUDA hardware acceleration.

Streaming Video Technologies Panorama, part 1 : Hardware-accelerated Encoding

Streaming Video Technologies Panorama, part 1 : Hardware-accelerated Encoding | Video Breakthroughs | Scoop.it

Maybe some of you remember the Tarari Encoder Accelerator for Windows Media which came on market in 2005 as a FPGA loaded PCI board. It was a 10K$ investment but it could seriously boost your encoder performances and it was a transparent solution for all encoders integrating Windows Media SDK. That was maybe the only real reliable option to do HD encoding decently at that time. More confidential were the Ambric cards for accelerating MainConcept H.264 and MPEG-2 SDK, which were found to be working with Inlet Armada transcoding farm.

Since these days, Tarari boards vanished, Windows Media encoding has been somehow outshined by H.264 and CPU performances have made great jumps, but the needs for hardware accelerated encoding solutions is still there, mainly because :
- H.264 encoding is also hungrily crunching CPU cycles
- screen types to feed have exploded with mobile, tablets, connected TVs and all other OTT devices
- adaptive streaming requires far more versions of the same file that previously mono-bitrate encodings
- available rackspace is not endless and it’s not convenient to manage hundreds of encoding nodes
- new formats like 3D and SVC are demanding strong encoding power
- you like to play with cool high-end encoders and you have strong convincing skills when it comes to make your boss buy expen$ive hardware


So let’s take a look at the different options available on the market now !
