Unsupported feature: Unsupported codec

[alexbilbie]

Hello,

I've managed to successfully compile libde265 and libheif however every HEIC photo I throw at the library I get the error Unsupported feature: Unsupported codec.

The following Docker script will compile libde265 and libheif under Debian and then run the example heif-convert from this repository but fail with the message above:

FROM buildpack-deps:stretch-scm

ENV LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

RUN apt-get update -y && \
    apt-get install -y libtool autotools-dev automake libx265-95 libx265-dev cmake libpng-dev libpng++-dev \
    libjpeg-dev g++ gcc libc6-dev make pkg-config

RUN cd /tmp && \
    git clone https://github.com/strukturag/libde265 && \
    git clone https://github.com/strukturag/libheif

RUN cd /tmp/libde265 && \
    git checkout frame-parallel && \
    mkdir build && \
    cd build && \
    cmake .. && make

RUN cd /tmp/libheif && \
    ./autogen.sh && \
    ./configure && \
    make

RUN cd /tmp/libheif && \
    make install

RUN cd /tmp/libheif/examples && \
    curl -LO https://github.com/strukturag/libheif/raw/gh-pages/example.heic && \
    ./heif-convert example.heic example.jpg

Please could you advise on how I can overcome this error?

Thanks

alexbilbie, I got the same issue, but i solved it by the steps below:

1. check if libde265 is supported during ./configure in libheif project
2. if no, then export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ , in where libde265 install the pkgconfig file
3. check with item 1 again, it should be libde265 supported

Your script is compiling libde265, but it is not installing it, hence libheif cannot find it in the configure step.
You might want to compile it like this:

• checkout libde265
• ./configure --prefix=SOMEWHERE.WHERE.IT.WILL.FOUND
• make install

Hi , I got the same problem.
I am using cmake-gui.exe in window 7 to generate the code.

..\libheif-master\build\examples\Release>heif-convert IMG_0004.HEIC testing.jpg
3
3
1
File contains 1 images
Could not decode HEIF image: 0: Unsupported feature: Unsupported codec

In \libde265-master\build\libde265\Release
I got
libde265.dll
libde265.lib

I think I should link the library to libheif
So in the cmake
I try to set
CMAKE_CONFIGURATION_TYPES Release;
CMAKE_INSTALL_PREFIX C:/John/libde265-master/build/libde265

I try many different path for
CMAKE_INSTALL_PREFIX

But doesn't work, I still got same error.

Can someone help me.

THX.

Folks experiencing this issue: when you ./configure libheif, it must say checking for libde265... yes or it won't be able to decode HEIC files.

I did install libde265 by cloning https://github.com/strukturag/libde265 and ./autogen.sh, ./configure, make then sudo make install but I still get this error for libheif

checking for libde265... no
configure: libde265 decoder: no

This worked. Thanks

For anyone who is reading this, the Dockerfile @alexbilbie posted actually missed some steps. Following the steps mentioned by @phanirithvij I finally get this to work.
