Add support to HEVC. I might be needed to use the libav.

hello ,
Thans for your dataset in advance . I want know weather you can provide the pre-procession dataset which meants using spherical linear interpolation . thanks a lot.

Add support to MS-SSIM quality metric in addition to the PSNR

I tried to install the project and I have the following error -

After googling for the error, I was suggested to use -lz but I couldn't figure out where to add the flags to the makefile. Can anyone point me in the right direction to fix this?

Scenario 1:
Run inside the example folder (or inside the /vagrant folder inside the VM):
trans -c Config_1.ini
This scenario reads the input.mp4 equirectangular video and transforms it into a 3x2 Cubemap video.
Outputs:
output1_1CubeMap.mp4 -> an HEVC 3x2 cubemap 360-degree video

The trans executable is created in the following path:

when i run trans with command ./trans -c ../, always face this error:
Error while parsing the Global.layoutFlow: No such node (Global.layoutFlow)
i use the default config.ini, doesn't change the layout flow, and i also have a Equirectangular video named tOffCopy.mp4 the path.
what's wrong?

When I implement : conan install .. -s compiler=gcc -s compiler.libcxx=libstdc++11 --build=missing , I meet some problem:

CMake Error at 3rdparty/ippicv/downloader.cmake:77 (message):
ICV: Failed to download ICV package: ippicv_linux_20151201.tgz.
Status=1;"Unsupported protocol"

And after google, I guess that it may be due to the opencv installment's error, I just install opencv under the path: /360Transformations/transformation/build/ConanEnv , but it does'not work!!!

And my enviroment is :
ubuntu14.04
git version 2.15.0
gcc (Ubuntu 5.4.1-2ubuntu1~14.04) 5.4.1
python3.4
cmake 3.22

Would you help me to have a look at what's wrong?

Thanks!

Hello,
Thank you for the useful codes and dataset.
I would like to know if your code handles the conversion between the HMD head position (in Euler or Quaternion format) to its corresponding pixel coordinates on the equirectangular projection.
A simple use case for this is streaming based on the FoV: a client that reads the head movement data instead of a real HMD head orientation data, and then stream the FoV from a server using DASH SRD.

Thanks in advance

Hi,
I have read your academic paper and I think it is an excellent work! But I have a few question about the pyramid projection. I think your implementation about this projection (which is shown in your code LayoutPyramidal.hpp and LayoutPyramidal2.hpp) is a little bit different compared with the one proposed by Facebook. Have you tried their approach?
Thanks!

Hi ,It's difficult for me to understand every transformation programs,so do you have a detail introduction of these transformations.such like code document,or some papers about the transformations.thank you

Hi,

Hi All,
Tried running the examples using the dockerized module:

Dear all,

    Once I have the input file (any file .mp4), I have extracted the viewports from the projected sphere in the plane.
I have used the following command:

trans -c Config_7.ini

However, the yaw pitch and roll are fixed for all frames. I can not control these parameters in each frame.

I need to control the yaw, pitch and roll in each frame.

For exameple, imagine a have 5 frames

Frame 1
rotation= {"type":"euler", "yaw":0.0, "pitch":0.0, "roll":0.0}

Frame 2
rotation= {"type":"euler", "yaw":10.0, "pitch":0.0, "roll":0.0}

Frame 3
rotation= {"type":"euler", "yaw":20.0, "pitch":0.0, "roll":0.0}

Frame 4
rotation= {"type":"euler", "yaw":30.0, "pitch":0.0, "roll":0.0}

Frame 5
rotation= {"type":"euler", "yaw":40.0, "pitch":0.0, "roll":0.0}


Is it possible to do it in this library?

Regards,

Dario

Guys,

 Any ideas how to sort it out?

Hi Xavier,
when i update my gcc version, and run the "make" the problem happens, i tried to add the extern “C” in the writer and reader.cpp, but still does work? would you help me to have a look at what's wrong?

It is easy to get that 3945 is greater than 3903, so why is the bit rate of the video with some high-quality areas and some low-quality areas higher than that of the original input video?

Could you help me solve my doubt？

Hi.

Thanks for putting this all together. This is extremely interesting. I've thought quite a bit about the problem, without implementing things directly. The two biggest questions I had and on which I was hoping to get your thoughts are:

• Is it possible to switch between representations before the end of the current segment? When the user turns fast for instance, the already streamed current segment is not very relevant anymore and it's be great to switch to the representation that corresponds to the new orientation without waiting 2s, if possible not streaming from the beginning of the segment frames that correspond to past time. The idea I had (which is not in ligne with the DASH framework) was something like:

  • each representation has two set of segment sets:
    • one where all frames are normal frames, with no key frames that we can represent like
      ..... ..... ..... ..... .....
    • one where all segments start with a key frame:
      |.... |.... |.... |.... |.....
  • when a representation starts to stream, a segment from the second set is streamed
  • when the same representation continues to stream, we use segments from the first set.
  • The idea is that while we're on the same representation, we don't stream expensive keyframes, which in turn make is possible to have much shorter segments, which would make the direction-adaptive streaming more reactive.

• Do you think there'd be issues with how the required storage and processing scale with the number of representations? For instance Facebook says they use 30 different viewports, which mean 30 times the storage and processing. So the complexity is Number of viewports * Number of available qualities What's your take on an approach that would be more similar to how google map loads data, where the space is split in regions and each is independently streamed, and represented in different quality settings. If we then need things to be more precise, this would only mean have smaller regions which would have smaller file size. So complexity would be Number of viewports * Number of available qualities / Number of viewports = Number of available qualities. That has the downside of having to stream from a number of sources and putting things together on the client, but would offer much more freedom on what is streamed and which part of the viewport should has it's quality changed.

Hi,

Thanks for your sharing.

I transform 360-degree video from Equirectangular to RhombicDodeca and it works.
However, it produces obvious and abnormal boundaries when I transform it back from RhombicDodeca to Equirectangular like the following screenshots.

rhombFace8Bitrate=1
rhombFace10Bitrate=1
rhombFace11Bitrate=1
rhombFace9Bitrate=1
rhombFace12Bitrate=1
bitrate=1

Is it normal with the obvious boundaries? Or, Is my config file something wrong?
Any suggestions are highly appreciated.

Thank you,
ShunHuai.

I have performed the download twice just to be sure that the box did not download correctly on the first attempt.

Each transformation takes too much time. Optimization seems needed

Like the question in the title, when I want transform equirectangular video to cubemap with target one bitrate. But the result video's bitrate is not same as I want in config file.

In the common.hpp, it's a error "error C2065,'i' Undeclared identifier"
the program is: template constexpr double norm(const SpacePoint& sp) {return cv::norm(sp.d);}
and also in front of "double" missed a ";"

Dear all,

I am working in a project that I need to extract a viewport from a 360 video frame and I have seen in the previous issues the LayoutFlatFixed class deals with this topic.
However, I have looked for in the folder of the project transformation/MainProject/src and I did not find any case that LayoutFlatFixed is used.
Could you please suggest anything to me?

Regards,

Dario

I think that there is a problem with your MS-SSIM function in file Picture.cpp (line 271)

//overall_mssim = prod(mcs_array(1:level-1).^weight(1:level-1))*mssim_array(level);
double msssim = mssim[m_nlevs-1];
for (int l=0; l<m_nlevs-1; l++)
{
msssim *= pow(mcs[l], m_mssimWeight[l]);
}
return msssim;

According to the paper "MULTI-SCALE STRUCTURAL SIMILARITY FOR IMAGE QUALITY ASSESSMENT" of Zhou Wang, the true formula of MS-SSIM is

So I think that in line 272 of your code, it should be

double msssim = mssim[m_nlevs-1] * m_mssimWeight[m_nlevs-1];
