Cinder-Hap block

in Developing Cinder • 5 years ago

CinderHap enables the Hap codec on Cinder.

Hap is an open source video codec for fast decompression on modern graphics hardware. Usually when a movie is being played, the CPU has to decompress every frame before passing them to the graphics card (GPU). Hap passes the compressed frames to the GPU, who does all the decompression, saving your precious CPU from this work.

Cinder-Hap has a new class called qtime::MovieGlHap that acts just like qtime::MovieGl. When a movie encoded with Hap is loaded, it will pass compressed frames to Hap. If the movie is not encoded with Hap, everything works like qtime::MovieGl.

qtime::MovieGlHap also brings some good extras to qtime::MovieGl!

Hap was developed by Tom Butterworth and comissioned by Vidvox.

For general information about Hap, read the the Hap announcement.

For technical information about Hap, see the Hap project.

Thanks for releasing this Roger! It's a very useful technology.

Is there a specific reason why the block is mac only? As far as I know the QuickTime codec required to make this work is available for OS X only at the moment, but it will surely change in the future.

The Hap codec was released for mac only, I'm not sure if it will be released for windows any time soon.

Cinder-Hap does not currently support Windows.

The repo has a few clues: the Hap codec added support for Windows support in May of 2014 but the Cinder-Hap repo hasn't been modified since April of 2013, MovieGlHap.mm (I don't see a .cpp file) is an Objective-C++ and the README explicitly mentions:

The Hap codec is developed for Mac OSX only, but a Windows version is in the works.

I'm sure if you forked the repo and added Windows support, they'd take a look at a pull request though.

https://github.com/brucelane/Cinder-Hap2 works with the glNext branch

it's a fork of https://github.com/mpcdigital/Cinder-Hap2

Thanks to Colin for his help!

Not complete, but it's 5am here, I need some sleep!

Hello,

I have a problem :

The last version of cinder branch glNext does'nt have these fonctions below :

pixelDataType( GL_UNSIGNED_INT_8_8_8_8_REV ).pixelDataFormat( GL_BGRA )

I can't compile !

Thanks

change：

//format.wrap( GL_CLAMP_TO_EDGE ).magFilter( GL_LINEAR ).minFilter( GL_LINEAR ).internalFormat( internalFormat ).pixelDataType( GL_UNSIGNED_INT_8_8_8_8_REV ).pixelDataFormat( GL_BGRA );

format.wrap(GL_CLAMP_TO_EDGE).magFilter(GL_LINEAR).minFilter(GL_LINEAR)

.internalFormat(internalFormat).dataType(GL_UNSIGNED_INT_8_8_8_8_REV).immutableStorage();

//mTexture = gl::Texture::create( backingWidth, backingHeight, format );

mTexture = gl::Texture::create(roundedWidth, roundedHeight, format);

mTexture = gl::Texture::create(roundedWidth, roundedHeight, format);

Finally correct.

Hello Mr. Zhang,

We are trying to implement your suggestion, but have difficulty in understanding exactly where we should implement it.

Could you please provide some guidance as to where exactly should we put this part of the code?

Thanks so much!

I've updated the block to latest the glNext, integrating these fixes: https://github.com/mpcdigital/Cinder-Hap2

It *should* now work out of the box on both Windows & Mac (quicktime legacy - mac deployment 10.7 - 32bit). Let me know if you run into any issues.

Hello everybody!

I need you help.

Is there any way to run HAP with CINDER 0.9(glNext) version in 64 or 32 bit mode on OS X 10.10 ?

I already try all available CINDER-HAP blocks, but no luck.

Found this - https://github.com/Vidvox/hap-in-avfoundation

But i'cant integrate objective-c code inside cinder, because i have some problem with TinderBox CocoaView project creation.

Any help would be appreciated!

Hello,
I tested with cinder 9.0 21_09_2015 on windows7 32bits

The sample HapMultiLayered with Cinder-Hap-2 don't compile
because
mTexture->getCleanWidth
                getCleanHeight()
                getCleanBounds()
                setSIze()
does't exist !

I update this block with cinder 9.0 21_09_2015
HapMultiLayered work well !

Hello,
I have a problem when I get Texture and draw the texture.
I don't understand glnext with clean texture :

last Glnext have :
mTexture->getActualWidth();
mTexture->getActualHeight();
mTexture->getWidth();
mTexture->getHeight();
mTexture-> setCleanBounds(...);

The old version have
mTexture->getCleanWidth
                getCleanHeight()
                getCleanBounds()
                setSIze()

Can you update Cinder-Hap2 or explain me please ?

Thanks a lot

I was able to update the Hap-2 to 0.9 and it compiled fine but I get an error when I load the video.

Failed to load resource: #129 type: GLSL

The thread 0x1cd4 has exited with code 0 (0x0).

and when running MultiLayered I get this --

Exception thrown at 0x747D5B68 in Monolith.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.

|error | cinder::app::AppBase::executeLaunch[137] Uncaught exception, type: class cinder::app::AssetLoadExc, what : Failed to load asset with relative path: SampleHapQ.mov

Thanks for any input.

Hello,

Very nice player but :

* play() and stop() calling is too long (the first frame remains displayed) !
Pause is very well optimized ?

* At the first playing I have a litte glicth !
How to properly load video in memory ready to use ?

Tested under windows 7 !

Thanks
