HomerHEVC:

HOMER (Hevc Open Mpeg EncodeR) is an open-source HEVC encoder to encode YUV420 video sequences to the new HEVC(H.265) stream format.

Thought it might be interesting for some of those HEVC experimenting folks out there.

Cool ... Had someone to build versions for testing.

I know nothing about programming.

[LigH.de]

Regarding the name ... how serious is this project?

[Marchand]

HOMER (Hevc Open Mpeg EncodeR) is an open-source HEVC encoder to encode YUV420 video sequences to the new HEVC(H.265) stream format.

Homer is still under development and will improve in quality and performance during the development.

Development is guided by three main aspects:

Easy portability.
Multiplatform (currently tested in Windows and Linux).
Performance.

Code style of the development is C'99 and recursive functions have been implemented in a sequential manner to avoid the drawback of recursive calls to complex functions and to ease portability. OS dependant code is isolated in a very simple file, while low level optimizations are handled with an interface for low level functions.

Current Features:

8 bit-depth.
All intra prediction modes.
All CTU sizes (64, 32, 16).
All transform sizes (32,16,8,4).
Sign hiding bit enabled.
RDO.
Wpp parallelization (native pthread or win32 threads, depending on the OS).
Fast decision mode algorithm.

Current SSE42 optimizations (intrinsics):

Intra prediction generation.
Prediction.
Reconstruction.
SAD, SSD.
Transforms.
Quantization.

Version Releases and Expected Evolution:

A new version (v1.0, v2.0, ...) is expected to be released every 4 months including new features and further optimizations. Reported bugs and small improvements of the already published versions will be published as soon as they are developed, being signaled by increasing the subversion index (eg. v0.1, v0.2, v0.3...).

Roadmap:

HomerHEVC_V0.1 (April 2014)

Intra smooth filter (To be added)
Intra skipped (To be added)

HomerHEVC_V1.0 (July 2014)

Inter prediction including interpolation filters.
Rate control (CBR, VBR, Capped VBR)
Further SSE/AVX optimizations & quality improvements.

HomerHEVC_V2.0 (November 2014)

SAO.
Deblocking.
Further SSE/AVX optimizations & quality improvements.

Compiling Homer:

HomerHEVC is composed of a simple example application (homer_app) and the encoder library (homer_lib).

Compile in Windows

Visual C++ 2008. Open the solution inside the "build\vc9\" folder and rebuild. Default project is for 64 bits.
Visual C++ 2012. Open the solution inside the "build\vc11\" folder and rebuild. Default project is for 64 bits.
Cygwin. Open the Cygwin console, go to the "build/Cygwin/" folder and type "make clean all" to execute the makefile.

Compile in Linux

Open a console. Go to the "build/Linux/" folder and type "make clean all" to execute the makefile.

Configuration:

These are a list of the configuration variables currently supported:

call: homer_app [-option] [value]...

options:

-h: help

-i: input yuv file

-o: output 265 file

-widthxheight: frame resolution, default = 1280x720 -cu_size: cu size[16,32 or 64], default = 64

-qp: fixed qp[0-51], default = 32

-n_wpp_threads: 0:no wpp, >0:number of wpp threads, default = 1

-max_intra_pred_depth: [0-4], default = 4

-max_intra_tr_depth: [0-4], default = 4

-sign_hiding: 0=off, 1=on, default = 1

-performance_mode: 0=full computation, 1=fast , 2= ultra fast

-rd: 0=off, 1=full rd , 2= fast rd

Configuration examples:

homer_app -i /home/juan/Patrones/720p5994_parkrun_ter.yuv -o output0.265 -widthxheight 1280x720 -n_wpp_threads 10 -performance_mode 2 -rd_mode 2

homer_app -i /home/juan/Patrones/720p5994_parkrun_ter.yuv -o output0.265 -widthxheight 1280x720 -n_wpp_threads 10 -performance_mode 1 -rd_mode 2

homer_app -i /home/juan/Patrones/720p5994_parkrun_ter.yuv -o output0.265 -widthxheight 1280x720 -n_wpp_threads 10 -performance_mode 1 -rd_mode 1

HOPE HAVE COMPILED PROPERLY

@LigH: there are more 'Homer' out there than just 'Homer Simpson' in example the greek poet.

[LigH.de]

Yes, I know ... computers and software are an own kind of Odyssee.

Another one of those missing msvcr1100.dll programs that rely on other files to use. I ain't got time to waste on these builds. If someone can build it to work in Virtualdub with stdin without having to use yuv or y4m as input then I'll try them out but the only ones that seem to work are Multicoreware's x265, DivX265 and DivX Transcode Engine.

[jcasal-homer]

This msvcr1100.dll problem is related to dynamic linking of system libraries. So, if you compile in one computer and execute in a different computer, you may get that error. To avoid it you can install the apropiate VisualC++ redistributable from windows or link libraries statically.

Windows Projects have been changed to link the needed system libraries statically from now on.

I have also downloaded some executables for windows 32 and 64 bits in sourceforge.

Thanks for the update.

[El Heggunte]

Hummm, the damn thing can't be compiled with MinGW, that's not good

Why the Linux trolls keep believing (or pretending) that Windows binaries MUST MEAN Visual C++ or Cygwin is beyond me -_-

[Selur]

Hummm, the damn thing can't be compiled with MinGW, that's not good

-> write a feature request / issue in their bug tracker over at github

[Sergio29]

Why the Linux trolls keep believing (or pretending) that Windows binaries MUST MEAN Visual C++ or Cygwin is beyond me -_-

Why the Windows stupid users like you keep believing that ?

[Baldrick]

Please try and discuss this without starting a linux vs windows fight.

Nice! Thanks for the info and work!

[jcasal-homer]

Selur!!

I am glad you like it.

I still have in my roadmap your suggestion to add input-output pipe support. I hope it will be ready for the following versions.

Regards

[Selur]

I keep my fingers crossed.

[Selur]

Nice! Thanks for the info and for keeping up the development !

[jcasal-homer]

Thanks to you Selur for being so enthusiastic with HomerHEVC

Regards

[Selur]

Still hoping for pipe input (or ffmpeg integration). (since that would allow me to add support for it inside my GUI frontend Hybrid)

[jcasal-homer]

You are right!!. It is expected to be ready in a couple of weeks. Let's hope this is be the good one!!

I'll post a message whenever it is released.

The development of the integration with Ffmpeg is expected to start in october.

[Selur]

Both good news!
Thanks for the update!
