High Efficiency Image File Format

High Efficiency Image File Format (HEIF)

HEIF is a visual media container format standardized by the Moving Picture Experts Group (MPEG) for storage and sharing of images and image sequences. It is based on the well-known ISO Base Media File Format (ISOBMFF) standard. HEIF Reader/Writer Engine is an implementation of HEIF standard in order to demonstrate its powerful features and capabilities.

Please follow this link to access HEIF Web-Site. You can also check the Wiki pages for more information.

For MIAF specific code, please switch to the MIAF branch.

News:

[25.06.2020] v3.6.0 Release: Added support for several new properties, image items with decoding dependencies, Extended type box and Type combination box, associating properties for entity groups, and reader support for segmented tracks. Minor improvements and code cleanup.

[10.07.2019] v3.5.0 Release: Improved support for JPEGs and edit lists. Bug fixes, minor improvements and code cleanup.

[06.11.2018] v3.4.0 Release: Java API improvements. Bug fixes, code cleanup and robustness improvements.

[13.06.2018] v3.3.0 Release: Java desktop build added, Java API includes track and image sequence as well as entity grouping support.

[06.04.2018] v3.2 Release. Two new APIs added, a Java API which wraps the C++ libraries using JNI and a convenience C++ API (which is used by the Java API) that wraps the underlying reader and writer. The Java API is expected to remain relatively stable, however the new C++ API will most likely change in the future.

[14.03.2018] v3.1 Release. Reader API update, bug fixes and examples update.

[05.03.2018] Code updated and tagged v3.0. Writer executable replaced with writer library / API. Implementation is based on HEIF standard specification ISO/IEC 23008-12:2017 that is available from iso.org web pages.

[09.03.2017] ISO/IEC 23008-12 second edition includes support for the interchange of multi-layered images. The source code now includes structures that are specified in this second edition. Simple support for AVC is also added. Minor bug fixes are included in this update. Example configuration files for generating multi-layered streams can be found in the Wiki.

[24.02.2016] HEIF source code and website is updated to reflect the latest HEIF specification changes and various fixes. Please note that backwards compatibility is not maintained during this update.

[24.02.2016] HEIF conformance test candidate files can be found here

Features:

HEIF is a media container format. It is not an image or video encoder per se. Hence, the quality of the visual media depends highly on the proper usage of visual media encoder (e.g. HEVC). Current standard allows containing HEVC/AVC/JPEG encoded bitstreams. This can be easily extended to future visual media codecs. It has many powerful features which are currently not present in other image file formats. Some of these features are:

• Encapsulate images coded using HEVC/SHVC/MV-HEVC/AVC/JPEG.
• Encapsulate image sequences coded using HEVC/SHVC/MV-HEVC/AVC.
• Storage based on widely adopted ISO Base Media File Format (ISOBMFF)
• Supports efficient storage of image bursts and cinemagraphs
• Supports computational photography use cases
• Supports both lossy and lossless image data storage
• A better and easy way to distribute still images, image collections and related metadata.

Please follow this link to see HEIF file examples.

Building source:

Prerequisites: cmake and compiler supporting C++11 in PATH.

cd heif/build
cmake --help
cmake ../srcs -G"<Generator listed by above command for your target platform>"
cmake --build .

Building Java API for Windows or Linux

Prerequisites: Java version 8 or newer, Gradle.

First build the C/C++ library as described above.

After that

cd heif/build/java-desktop
gradle build

Note that in order to run the Java API you need to have the HEIF JNI library built in the earlier step (heifjni.dll or heifjni.so) in the Java library search path.

heif's Issues

How can I get the (heic)image's info from exif?

How can I get the image's info from exif?
Like jpg, it can use libexif for get image's info from exif, but it can't support get image's info from heif file's exif!
Thank you！

Please make a viewer

I compiled this but don't know what to do with writerapp, it needs some kind of config file. It would be great to have a viewer binary.

Where can I download the files of writerapp and example？

Multiple compile errors with VS 2015

There are no Visual Studio project files, so I've had to craft them by hand. Most of the project is building fine, but I'm getting numerous complaints of the following form:

1>Srcs\writer\datastore.cpp(39): error C2065: 'not': undeclared identifier

where the offending line is:

if (not mValueMap.count(key))

not is not the boolean negation operator in C++, the standard very clearly defines ! as this operator. Is there any good reason for attempting to use a non-standard operator, I'm not sure I can see how doing so adds any value to the project.

Does this project support msvc?

How to convert HEIC to HEVC by JAVA

I'm not find the API of the JAVA and some examples about my question.
Who can tell me how??? plz

call cv::VideoCapture vcap(filename)；

OpenCV: Couldn't read video stream from file "/Desktop/temp_bitstream.hevc"
cv::VideoCapture::isOpened returned false

corrupted tile in grid

I'm having trouble converting HEIC files from an iphone to a jpeg. The files contain 8x6 grids of images and every file, apart from some inputs, such as panorama shots(not 8x6 grid) have the 7th tile corrupted.

see attached file:

I put some code in a github repo: https://github.com/Kimbsen/heiftest to reproduce the problem. the code there is pretty self explanatory.

Any ideas what i might be doing wrong? I've excluded rotating the image though it should have been rotated 270 degrees as the problem is present regardless.

Fix typos in the README.md

The file contains some typos.

Comparison isnt accurate

JPEG is outdated. And its out of the league. Same with GIF.
Since you suggest new format, that not yet fully supported you have to compare with competitive alternatives:

• JPEG2000
• WebP
• FLIF (+ animation)
• WebM (animation)
• MP4 (animation)

Look what google did: https://developers.google.com/speed/webp/docs/webp_study?csw=1
Use PSNR / SSIM

Dont get me wrong, you publish closed source codec, compare it to previous century technologies, and expect we would adapt it. No way. x265 is great since it has intel(and probably amd) cores support, but. but. It weren't adopted by any browser, nor would be adopted(except probably Safari, cause they don't mind closed source). Meanwhile almost every end-user app nowdays either hybrid or pure web.
On other hand we have WebP, which already implemented in Chrome&Opera&Android + UC (74% of world traffic consumers), and on his way in Firefox&Safari team.

If you really want your work to be worthy, you have to put some effort to it. We have tens of image format alternatives, same as with compression algorithms.

ImageFileReaderInterface::FileReaderException

...
    HevcImageFileReader reader;
    ImageFileReaderInterface::DataVector image_data;
    ImageFileReaderInterface::DataVector auxl_data;
    ImageFileReaderInterface::IdVector itemIds;
    reader.initialize(file_name);
...

The last line has an error:

terminate called after throwing an instance of 'ImageFileReaderInterface::FileReaderException'
what(): Error while reading file.

So I used gdb to debug my program, I found the exception is here:

But I dont know why...

Build issues: snprintf not declared

Hi,

i wanted to build the library using windows with cmake and mingw.
cmake runs properly and when compiling the source using make i get an error when it comes to the
jsonLib:

D:\development\Libs\c++\heif-master\Srcs\jsonlib\jsoncpp.cpp:1035:70: error: 'snprintf' was not declared in this scope
snprintf(buffer, sizeof(buffer), "Line %d, Column %d", line, column);

and so on.

Anyone has an idea what i am doing wrong?

Thanks
Sebastian

Refactor dynamic_cast so we can disable RTTI

Refactor the very few lines of the library that make use of dynamic_cast so we can compile it without RTTI.

how can I run it with JAVA

My build command are as following, and succeed:
sudo cmake ../srcs
sudo cmake --build .
I see the directory "heif/srcs/api-java" has "cpp" and "java" two directories, and HEIF.java has "System.loadLibrary("heifjni");", but in directory "heif/build/lib", I can't find heifjni.so or heifjni.a.
How can I build heifjni file?
Looking forward to your reply.

Add AV1 support

No modern royalty free codec is supported currently.

AV1 is a reasonable option, and has very broad industry adoption.

.heic files given in gh-pages/content/images not according to ISO/IEC 23008-12:2017 spec

As per the HEIF files spec, files cmpatible with brand 'mif1' should have 'iinf' box version as 0 or 1 but the files given at ''https://github.com/nokiatech/heif/tree/gh-pages/content/images' have the version 2 of this box.
Our metadata parser is written according to the HEIF spec and it is rejecting these files.
Can anybody let me know if I am missing something here?

A problem about iPhone heic

Dear Nokia Developer,
I know a typical iPhone heic picture has 48 tiles, and I extract all tiles into H.265 bitstream successful. Then I use ffmpeg convert them to png，I get all 48 still tiles picture finally.
But it's not I wanted. I try to put all decoder tile into one memory buffer, just converting one times get the complete png picture. Because I think maybe I could get a picture, not 48 tile. But I don't know how to set the HEVC NAL Uint at the beganing of memory buffer. What should I do? Or the mathod cannot make it?
My part code

Array<ImageId> gridIds;
Grid gridData;
Array<ImageId> tileItemIds;
if(reader->getItemListByType("grid",gridIds) == ErrorCode::OK)
{
    tileItemIds = gridData.imageIds;
    if(reader->getItem(gridIds[0].get(), gridData) == ErrorCode::OK)
        {
            tileItemIds = gridData.imageIds; // 48 tiles
            
            // Calculate size of parameter sets, but do not copy the data yet.
            size_t parameterSize = 0;
            DecoderConfiguration decodeConf;
             if(reader->getDecoderParameterSets(tileItemIds[0], decodeConf) == ErrorCode::OK)       
             // I konw the decodeConf is not I want 
            {
                for (auto& config : decodeConf.decoderSpecificInfo)
                {parameterSize += config.decSpecInfoData.size;}
            }

            }
            itemSize = memoryBufferSize - static_cast<uint32_t>(parameterSize);

                else{cout << "Get Image Data error!" << endl;}
                
                memoryBufferSize = static_cast<uint32_t>(parameterSize) + tileSize;

Can example7 not encode images taken by the iphone8?

Can example7 not encode images taken by the iPhone8?

Is there an interface that can be exported directly to a buffer that I define, rather than having to output to a file?

Please register mime types for HEIF and HEIC in IANA

Mime type for HEIC and HEIF must appear here:

https://www.iana.org/assignments/media-types/media-types.xhtml

This is a requirement of major operating systems in order for them to include mime types by default on their config files. See this bug report response, where I tried to make standard Apache on Linux be aware of HEIF/HEIC thought mime types: https://pagure.io/mailcap/issue/1

Thank you in advance

请问在centos7上编译通过之后，怎么执行？

我在centos7上用cmake对源码进行编译，生成了可执行文件，但是我不知道下一步该怎么做，是要用一个实例去调用吗？

Is there any examples for storing depth map in *.heic?

It is said that depth map can be stored as an auxiliary image in a heic file. I wonder in what format will it be stored. In raw data? Or maybe use some method to encode the information?

crash when i use example1()

Can I use the code here to convert jpg to heif format online on our company's website?

Can I use the code here to convert jpg to heif format online on our company's website? I first use ffmpeg jpg into h265 format images, and then modify the code to use nokiatech / heif here, online conversion heif image format

Finally, on the terminal, use other sdk to parse the heif image format

problems building

Using git source.

The only thing built is writerapp. No reader, etc.
And "make install" gives me "No rule to make target 'install'".

I don't know much about cmake, so I'm not sure what to do.
I have cmake 3.9.1 and GCC 7.1.0, BTW.

can I use heif library encode JPEG to HIEF?

I run all the examples,but I find that none of the examples can encode JPEG to heif

DecodePts::applyShiftEdit - Attempt to deference an invalid iterator

In the line 177 of the file decodepts.hpp you have
if (std::prev(it) != mMediaPts.cbegin() &&...

I believe what you intended was
if (it != mMediaPts.cbegin() &&...

I happened by this bug when to use the C036.heic (found on your own repository) with the reader.

A simple
HevcImageFileReader reader;
reader.initialize("C036.heic");
is enough to reproduce the problem.

Problems with decoding the 7th tile on JavaScript

Problems with decoding the 7th tile. When you try to decode the 7th tile, then there are problems. Here already wrote, how to solve this problem on c++, but nothing about JavaScript.

I tried to rewrite it on the JS, but nothing came out. Is it even possible?
Somebody did the decoding onJavaScript?

HevcImageFileReader::initialize does not reset internal state

HevcImageFileReader::initialize does not reset the class internal state.

That means that if have more than one file/stream and we attempt to reuse an instance of the HevcImageFileReader class to read the next one, all the data from the previous stream will still be there, resulting in crashes (when you are lucky)

What's the term of using this library in a commercial project?

Hi!
I'd like to use this library in a commercial project. However, the license is not clear about this. Could you explain to me whether it is possible at all?

Write EXIF tags to HEIF

In example 8 EXIF data is read from a HEIC file. Is it also possible to go the other way around: write EXIF data (for instance read from a JPG file) into a HEIC file?

Can't Find Image Data

I am trying to make a simple Heic image viewer. I was able to link the libraries okay and find the height and width of an image. However, I can't find the routines that get the bits per pixel or the decoded image data.

Do I need codec just to view simple images? Is there a simple way to get the image data?

Thanks.

building and installing instructions

Hey,
I am maintaining https://aur.archlinux.org/packages/heif/ but I have troubles updating to the latest v3.0 release.
It would help alot if the README would have some building and installing instructions.
Thanks
