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.

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.

Microsoft Releases Expression Encoder 4 SP2 with QuickSync encoding acceleration

Microsoft Releases Expression Encoder 4 SP2 with QuickSync encoding acceleration | Video Breakthroughs | Scoop.it

Pro users will gain GPU-accelerated encoding with the Intel HD Graphics GPU included in Sandy Bridge processors. NVIDIA CUDA support has also been improved.

 

The program now offers 1- and 2-pass variable bit rate encoding for H.264-based Smooth Streaming (in the Pro version), support for more bitrate and sample rate options when using the AAC codec, and support for SRS audio encoding.

Intel Engineer Ports QuickSync Video Decoding to FFDShow

Intel Engineer Ports QuickSync Video Decoding to FFDShow | Video Breakthroughs | Scoop.it

An Intel engineer by the name of Eric Gur started an AVSForum thread indicating he had begun work on enabling Quick Sync support in FFDShow's video decoder. Quick Sync is typically known as Intel's hardware accelerated transcoding engine found in Sandy Bridge, however there are both encode and decode aspects to the engine. Gur's work focuses on the latter.

 

To access Intel's hardware video decode acceleration application developers typically turn to the DirectX Video Acceleration (DXVA) API. Sandy Bridge's hardware decode engine interfaces with DXVA and can return decoded frames not run on the x86 CPU cores. As we've lamented in the past, open source DXVA decoders haven't typically worked all that great for Sandy Bridge (or previous generation Intel GPUs, for that matter). FFDShow users have often avoided DXVA solutions as they can't be used with any custom post processing FFDShow filters.
