Current HEVC test model does not have a rate control algorithm integrated.

Does anyone know how to use constant bit rate (or control rate like H.264) in HM4.0 encoder.

I want to learn about h265, please instruct on how to download the software…
It would be really helpful
thanks

Hi, I’ve been testing HEVC (HM4.1) and it produces expected results with most test sequences using high efficiency and random access. But for sequences with small number of frames (like one view of BookArrival with 100 frames 1024×768) it produces a similar bit rate when compared to H.264/AVC (just 4% ~ 20% less)… Specially for higher QPs (which is understandable for QP). Does anyone know why the results are so inferior for these small frame number sequences? I think something like this would be expected for low resolution images not low frame number sequences…

Hi，how can I use C program to realize DCT in HEVC？

I can’t download the codec, where is the link?

Mars,
You have to wait until the HVEC codec is finalized and optimization has completed, this code is proof of concept only. For real time performance it will take additional time for a hardware acclerated encoder to be implemented.
For the foreseable future you really have to look into hardware encoded h264 for good quality at real time performance…

Hello!
I test the code and find out that HEVC’s compression ratio is good ,but the coding speed is too slow. I costed 1.76h to encode 300 frames which is YUV420 352*288 ,using encoder_lowdelay_loco.cfg in the project. I want use HEVC in real-time business. How to make HEVC’s encoding speed more faster, which parameter should i set？ Please help me .

Hi Dr. Liu,

I’am using the software HM-2.0. After make I typed this command:
./TAppEncoderStatic -c ../cfg/encoder_randomaccess.cfg -fr 30 -f 10 -i Flowervase_416x240_30.yuv
and got the following error:
POC 0 ( I-SLICE, QP 32 ) 208 bits [Y 99.9900 dB U 99.9900 dB V 99.9900 dB] [ET 0 ] [L0 ] [L1 ] Segmentation fault

Could you help me, please?

Thank you in advance.

Hi ppl,
I am trying to implement hm 4.0 on ti ccs. Can somebody help me with what files to include in the project. I am getting a linker error.

Thank you in advance.

Compilation fails for me in Linux unless I remove “-Werror” from CPPFLAGS in build/linux/common/makefile.base

to doris:
Is your network using proxy? If you do this, you should edit files of svn.

to John Ogah::
You can change it in cfg files which are in cfg folder, not in the cfg/per-sequence one.

Why I cannot to download HM any version from repository?
I installed TortoiseSVN, made all following instruction, but it says “couldn’t connect to repository”.
Tell me please, how is it possible to download HM.

Hello, how i can lauch it? i have downloaded HM3.2rc1 and how i execute aplication? or i must build it first in some compiler?

Hi Lu Liu:
Is there is a re-defined *.cfg file for the Low complexity and High efficiency in the HEVC software (HM-1.0 or the latest )
and one more thing the bitrate in the HM software is measured in bit/s or Kb/s?
thanks

Hi,

I have a question, when syntax of bitstream in reference software and in working draft will be unified? I need to save in text file all syntax elements of bitstream, but it is hard to do in present reference softwere. It was much more easy to do in reference sofwere to h.264 standard…?

Thanks for any replying.

This article is great, when can you finish it? or it has already been finished?

Does anyone know how to compile the software HM2.0 in ubuntu?I just type command: $make.But it doesn’t work.

Dear Sir,

I could build the code in Windows and both encoder & decoder working fine.
However, if I try to build code unders linux using cygwin,by running command :
$ make
I get error.
So, please let me know:
1. Can we build code using cygwin?
2. Does it require any other command line parameters in make command?

Thanks & Regards,
Dr. Ganesh Bhokare

Hi what is the difference the TMuC and the HM software.In HM why the MD5 algorithm is used ? Hope you reply soon ..

Can anyone help me ? I got the following error
HM software: Encoder Version [2.0][Windows][VS 1600][32 bit]
Error: QuadtreeTULog2MaxSize must be 5 or smaller
I tried to change it the max size in racehorces.cfg but I couldn’t find any input as this?

By the way, would the name of HEVC be changed to H265 in the future?

Hi Lu Liu:
Thank you for the detailed answer! I’ll reconfirm with other HEVC researchers about the usage of these sequences for academic usage.

Why do the web pages that is thanslated display just a piece, and the other part is covered by the blue background？Is it a problem of wire speed or others?It’s really not convenient.

Thank you very much, Mr Liu, it’s very nice of you.
I have another problem.I have been studying the HM software and its edition is 2.0 in which the complex structure and too long variable makes me puzzled. Can you tell me how to study the HM, and is there the help document or other file can solve my problem , which, I think is others’problem.
Thank you for replying.

In the Annex A of document VCEG-AM91, Joint Call for Proposals on Video Compression Technology, it lists the copyrights of test sequences. The usage of sequences is subjected to one of the following statements:

C1: This material may only be used for the purpose of developing, testing and promulgating technology standards.
C2: These materials shall be used, copied, modified, or distributed only for developing MPEG and VCEG High-Performance Video coding standards and for testing and promoting such standards.
C3: This material may only be used for the purpose of developing, testing and promulgating technology standards.
C4: These sequences may only be used for the purpose of developing, testing and promulgating technology standards.
C5: These sequences may only be used for the purpose of developing, testing and promulgating technology standards.
C6: This material may only be used for the purpose of developing, testing, and promulgating technology standards.

But, I am not sure whether it is legal to use those sequences for the academic use.

Hi Lu Liu:
Thanks a lot for your information that is very useful to us video codec researchers! However, I’m wondering whether those sequences are FREE to public, i.e., is it OK/legal to publish a paper about HEVC using those sequences and config files without registering those HEVC meetings?

no, only English version. However, you can use the “Translate it” at the top-right corner to translate the webpage to your desired language.

Thank you for share it.
