That would seem reasonable.

My earlier comment was based around the misunderstanding that you were 
making software that included the codec.  If you're just using other 
people's software then of course their EULA describes their software's use.


It's nice to see that Sorensen has paid the extra multi-million dollar 
fee for their customers' commercial use that Apple didn't for Final Cut Pro.

This is what I would expect.

If you produce and distribute a program which includes an H.264 
compressor or decompressor then you need to pay patent license fees (in 
actual fact, I suspect even if you don't distribute said program, and 
use it to generate compressed video, you still need to pay patent 
license fees).


So, if you use a third-party product you have bought (like Squeeze), and 
OS included codecs to playback the video (like AVFoundation and 
DirectShow used in LiveCode) then that has already been taken care of 
for you.


In regards to the 'stepping' - it might worth asking Sorenson (who sound 
very helpful!) about that. In particular with regards DirectShow. Having 
a key frame every frame I'd have thought would vastly reduce the effacy 
of compression - so I wonder if there's some other tricks to encoding 
which would let it work in DirectShow, the way you want.


Alternatively, if you can find an open source program which *does* allow 
stepping through H.264 videos via DirectShow on Windows then let us know 
and we can see if it is possible to make DirectShow do that without 
special encoding options. (After all, if AVFoundation lets you do it for 
an arbitrary H.264 encoded video, then you'd think it would be possible 
for DirectShow to; on the other hand, AVFoundation I think is newer and 
perhaps 'better' than DirectShow due to that, so it is very hard to 
say!).


Warmest Regards,

Mark.

Choosing a codec is a complex issues given the scope and variety of their
patent licensing.

My lay person's understanding is that x264 is available under GPL, so it's
useful for GPL-governed works but as you've noted isn't as widely available
across the many platforms we may choose to support.

H.264 is a good codec technically and has wide distribution, but AFAIK
remains mired in a patent pool so complex it needs an FAQ to try to explain
it:

terms:

One of the open questions for us software developers is the case of
distributing commercial tools that use H.264.  Apple and Microsoft have
their own license arrangements with the MPEG-LA consortium for distributing
the codec with their respective OSes (perhaps easier for Apple since they're
a member of that consortium), but we may need to review the OS EULA to
determine the allowable scope of use for the codec in our own commercial
software products.

For example, here are relevant sections of the Final Cut Pro X EULA, which
make it explicitly clear that despite the product's name professional use is
disallowed:

This product is licensed under the MPEG-4 Visual Patent Portfolio
License for the personal and noncommercial use of a consumer for

Tiemo,

x264 is only an encoder and does not need to be installed on a client 
machine to enable playback if that's your concern. Whether or not the 
videos are compatible will depend on thoughtful selection of encoding 
options. In this regard x264 offers almost unlimited opportunity to 
experiment (glass half full) and choose badly (glass half empty). 
 The Intel encoder has the 
advantage of using the gpu, where applicable, to accelerate encoding. If 
you've found something that works, it wouldn't be a bad decision to have 
a celebratory beverage of your choice and think about something else!

Intel QSV H.264 codec for AVFoundation and DirectShow

[Tiemo Hollmann TB]

Hello,

I made some tests with LC 8.1.0 dp1 to find a video codec solution, as a
replacement for QuickTime which fits for both platforms windows and OS X.

I am looking for the most standardized state of the art codec to get a
maximum of compatibility on both platforms, so I think H.264 is the right
choice.

My special requirement is, that I have to step thru the video frame by frame
controlled by LC.

My sorenson squeeze compressor offers 4 different H.264 codecs: "Intel QSV
H.264", "MainConcept H.264", "Sorenson MPEG-4", "x264"

My LC tests showed me, that I need to set a keyframe every single frame to
be able to step thru the video framebased (at least with DirectShow). This
option do only the intel QSV and the x264 codec offer.

The x264 codec is a opensource codec and as far as I understand it is not
preinstalled on any system and at least on my Mac a x264 video can't be
played (perhaps there is a chance to manually install it, what I would like
to avoid for my customers)

So up to now it seems to me that only the intel QSV H.264 is left of my
choices. It should be supported from Windows Vista on and from OS X 10.8 on.

 

Has anybody experiences in this field of codecs, other experiences or tipps
or would negate some of my conclusions?

 

Thanks

Tiemo
