The applications existing video processing filter operations are applied and completed between the decode and encode processes.

However, HandBrake has been a CPU-only conversion application.

Offloading the transcoding to the Intel HD Graphics provides several benefits.

First, the transcoding is quicker compared to the traditional CPU-based approach.

Also by using the dedicated circuits in the Intel HD graphics you not only get a speed in performance but it also consumes less energy allow you to conserve your battery for other activities.

Our goal in this effort was to improve user experience for HandBrake by extending it with support of HW acceleration while running on Intel architecture.

This video conversion process is very similar to when some put audio onto their smartphone, table computer, etc.

The process is called transcoding when the source video is decoded, transformed (changing resolution, bitrate, frame rate or applying filters and the encoded (format into a format that is viewable on the consumption device.

Transcoding video has traditionally been done in software on the CPU but with the introduction of the Intel 2nd Generation Core Intel now has dedicate circuitry within the processor graphics that allow this process to be hardware accelerated.

It has averaged more than 650,000 downloads per month in the first seven months of 2013 on Sourceforge.

Before Handbrake, we used other applications to convert video files to shareable file types, but we had to use three or four different utilities to get the file from our cameras.MOV format to the right.MP4 or.AVI format.

File sizes were often too large.

Handbrake has profiles that support all of these, and customization is possible through personal settings create customized profiles.

Pick the target device from the profiles included in Handbrake and you are on your way.

We approached their team to see if they wanted to collaborate to find ways to improve execution performance while keeping the user experience where users had come to expect.

The executable for these builds can be downloaded at the nightly build link from the download section on the main HandBrake website.

Hardware acceleration did not natively run within the application, so we dissected the internal workings of the program to see if we could have it utilize this feature natively.

Additionally, we used our Intel Media Software Development Kit (Intel Media SDK) API to understand and work with Intel Quick Sync Video effectively.

The Intel and HandBrake teams put our heads together to identify the steps needed to add Intel Quick Sync Video Intel HD Graphics acceleration to the project.

This resulted in a list of functions we could start working on, including Intel Quick Sync Video-based H.264 decodeencode and Intel Quick Sync Video-based filters.

Since we wanted to achieve the best performance possible, we needed to adjust internal pipelines, queues, and their corresponding sizes.

To improve performance in this area, we adopted testchange approach to achieve the best possible results with Intel Quick Sync Video in HandBrake.

Currently, our experiments using the H.264 Intel Quick Sync Video codec show Intel HD graphics on Microsoft Windows 8 utilization approaching 100 while the CPU utilization remains under 20, allowing for a full speed transcode since the dedicated Intel HD graphics is not affected by the other computing tasks the CPU must always attend to.
