In order to determine the OPEX savings gained from using the
IDT H.264 codec vs x264, we modeled the cost of encoding a single
live channel of 1080p30 running for a month. The OPEX savings
depends on the average number of concurrent viewers for that live
session. The calculations below are based on published AWS prices
for North America as of June 2018—$0.848 for a C5.4xlarge On-Demand EC2 instance, and $0.02 per GB of On-Demand Cloudfront
CDN at largest volumes(over 5PB/month).
As can be seen from the analysis, for a live session of up to
150 average concurrent viewers, the maximum savings is gained
by cutting the transcoding costs by 50% based on IDT H.264
codec double density over x264. For sessions with more than 150
concurrent viewers, maximum savings is established through
CDN cost reduction by transcoding to the same quality at 20% less
bandwidth using IDT H.264 codec at similar densities to x264.
SEAMLESS INTEGRATION INTO FFMPEG WORKFLOWS
Transcoding with ID T’s encoder is a snap due to its integration
as an FFmpeg plug-in, leveraging the use of existing FFmpeg
filters for demux, multiplexing, graphics overlay, and video frame
scaling. Whether your workflow currently uses FFmpeg or x264
standalone, IDT’s H.264 encoder can be seamlessly integrated into
your existing video processing pipeline and architecture.
Control System works in conjunction with other processes on the
system such as system management control, audio transcoding, etc.
The ID T H.264 codec offers huge savings by enabling cloud video
systems to reduce the number of live encoding instances by 50% for video
sessions that require a small number of viewers such as user-generated
content or gaming, as well as reduce overall bandwidth by ~20% when
average viewership is in the hundreds and above for segments such
as media & entertainment, enterprise videos, video publishing, etc.
By offering the same integration into FFmpeg as the open-source
x264 codec, the IDT H.264 codec can be easily plugged into existing
workflows, and video ISVs of all sizes can take advantage of the best
H.264 codec powering most of the professional broadcast TV industry.

IDT COMPUTATIONAL CONTROL SYSTEM
ID T’s unique Computational Control System (CCS) is built into
the IDT’s real-time live compression products, to dynamically adapt
on-the-fly to incoming varying scene complexity and allocate CPU
resources across multiple encoding instances. More resources
are allocated for more complex scenes, while fewer resources are
allocated to less complex scenes. This maximizes the visual quality
across the entire server/cloud instance while maintaining consistent
real-time performance. IDT’s control system will use spare cycles
when available and will gracefully reduce the video toolset when out
of cycles to maintain real-time encoding performance. There is no
need to add overhead margin for CPU cycles as the Computational
