 I also want to use it if you can integrate Intel QSV decoding and VPP
 filtering features into ffmpeg,and I can pay for you if your integration
 can work correctly.

Comment (by Mjb2000):

 Apologies for posting a question here, but you guys seem pretty smart so
 you'll probably know the answer straight away.

 I'm trying to compile a version of ffmpeg with quicksync support for use
 in a Windows environment. I've used the pre-compiled binary from the
 drocon11 fork, but unfortunately I need a few other libraries included in
 the binary (so this is why I figured I need to build this myself?).

 I'm just a little confused with the exact environment and tools I should
 be building with. I've tried to follow the various instructions within
 some of the dependencies but for instance I couldn't even work out if I
 should be doing this in a msys on Windows, or within Linux.

 If somebody could outline with a bit more detail how I should go about
 building the drocon11/ffmpeg-qsv project I'd  really appreciate it.
 Particularly if you could mention the OS, tools and any installation
 guidelines I should follow that would be great.

 If it helps, the background to this is that I have a low power j1900 cpu
 running media browser 3 as a media server, but the cpu struggles why real-
 time transcoding, however the j1900 supports quicksync and I can get some
 pretty good performance using quicksync. Unfortunately, the way in which
 media browser uses ffmpeg seems to require some additional libraries which
 are bit included in the drocon11 build.

 Thanks again, Matt

 So if I understand what you are saying… there is not even a non-default

 helped here. In this instance I really don't understand how the LGPL is

Comment (by dreamcat4):

 A fork of ffmpeg has implemented quick sync support.

 https://github.com/drocon11/ffmpeg-qsv

 HOWEVER, like all similar before it - depends on the Intel Media SDK as a
 build requirement. Which Intel only provides Windows and Linux. (no OS X,
 no FreeBSD).

 So it is probably needing some pre-compiled assembly, DLL or ELF / .so lib
 files to link from the Media SDK.

 Maybe if the only dependancy was on C files  headers. Then something
 truly portable could be built for all platforms. So perhaps the best hope
 is to ask nicely, beg and borrow from the VLC team*.

Comment (by snickers2k):

 Wikipedia:

 Linux
 Quick Sync support by Intel Media SDK on Linux is available,[9] although
 as of March 2013 no application has been reported to integrate it.

 Microsoft Windows
 Microsoft offers a wide support for Quick Sync in Windows based on
 supporting driver software from Intel and good support through both
 DirectShow/DirectX as well as WMF (Windows Media Foundation). A wide range
 of applications are based upon this base support for the technology in
 Windows. Windows support is available from Windows Vista onward.

 OS X
 Apple added Quick Sync support in OS X Mountain Lion for AirPlay
 Mirroring, FaceTime and QuickTime X.[10] iMovie 10 uses Quick Sync when
 exporting videos.

Comment (by Rodeo):

 In my experience, Quick Sync is most useful when it handles both video
 decoding and encoding (much lower CPU usage, fan noise and power
 consumption) - and that's where Quick Sync will outperform x264 ultrafast
 by a large margin on consumer-grade hardware. Still, Quick Sync encode-
 only can also outperform ultrafast on just about any ultrabook, AFAIK.

 FWIW, there is ongoing to work to integrate QSV as a hwaccel in Libav:

 https://github.com/maximd33/libav/tree/qsv
 https://github.com/DonDiego/libav/tree/qsv

 Only H.264 decode is implemented so far, IIRC - haven't been following
 this very closely though.

 According to my research and actual use, it may be worse quality than
 libx264 but it's faster.  Additionally, it's hard to notice much of a
 difference when transcoding for mobile devices anyway.

 I did not find any comparison between x264 and QuickSync in this article.
 Did I miss it?

  http://forum.doom9.org/showthread.php?t=166958

 It is claimed here that x264 Ultrafast is faster than QuickSync.

 
http://www.compression.ru/video/codec_comparison/h264_2012/mpeg4_avc_h264_video_codecs_comparison.pdf
 seems to indicate to me that QuickSync has no advantages over x264 but
 maybe your results are different?

 They used x264 in their handbrake test:  We took the profile and
 performed the same transcode, the result is listed above as the Core i7
 3770K (Handbrake). You will notice that the Handbrake x86/x264 path is
 definitely faster than Cyberlink's software path, by over 50% to be exact.
 However even using Handbrake as a reference, Quick Sync transcodes over 2x
 faster.

  It is claimed here that x264 Ultrafast is faster than QuickSync.
 
 One poster states ultrafast is probably quite a bit faster than quicksync
 but provides no report of his actual experiences.  Towards the bottom of
 the thread 2 users share their experiences that Quick Sync is faster.  In
 my experiences, Ultrafast is pretty fast but still not as fast as
 QuickSync.  It also maxes out all 4 of my CPU cores rendering my machine
 pretty useless.

 seems to indicate to me that QuickSync has no advantages over x264 but
 maybe your results are different?

 Thanks for the link.  The conclusions behind appendix 6.6 might point to
 reasons that my platform doesn't perform as well with x264.  From the
 comparison:  This test shows that using Laptop hardware with weaker CPU
 with basic integrated GPU hardware encoder QuickSync is better in terms
 speed/quality trade-off than best pure software encoder x264 at very high-
 speed encoding.

   I did not find any comparison between x264 and QuickSync in this
 article. Did I miss it?
  
  They used x264 in their handbrake test:  We took the profile and
 performed the same transcode, the result is listed above as the Core i7
 3770K (Handbrake). You will notice that the Handbrake x86/x264 path is
 definitely faster than Cyberlink's software path, by over 50% to be exact.
 However even using Handbrake as a reference, Quick Sync transcodes over 2x
 faster.

 This is missing the clarification that they actually tested with ultrafast
 and superfast (and possibly some finer presets in-between to test how
 quality compares at the exact same speed), but please understand that I
 did not want to move the discussion here (I very rarely encode to h264 and
 have honestly no opinion on this matter), I just wanted to warn you that
 more educated people on this matter than I am think that once this is
 implemented you will be very disappointed with the results.
 Otoh, if you need to use your CPU while re-encoding, hardware encoding may
 have its values (if you don't care about the encoding quality).
