Linux Build

Linux Installation

The README in the main github repository will always be kept uptodate for current builds and basic user guide help.

Linux Compatibility Doc

Install all dependencies required by LD-Decode and VHS-Decode:

sudo apt install clang python3-setuptools python3-numpy python3-scipy python3-matplotlib git qt5-default libqwt-qt5-dev libfftw3-dev python3-tk python3-numba libavformat-dev libavcodec-dev libavutil-dev ffmpeg openssl pv python3-distutils make cython3 cmake pipx

For Ubuntu 22.04 that is:

sudo apt install clang python3-setuptools python3-numpy python3-scipy python3-matplotlib git qt5-qmake qtbase5-dev libqwt-qt5-dev libfftw3-dev python3-tk python3-numba libavformat-dev libavcodec-dev libavutil-dev ffmpeg openssl pv python3-distutils pkg-config make cython3 cmake pipx

Set up pipx

pipx ensurepath

(Alternatively, a python virtual environment can be used instead of using pipx)

Install TBC-Video-Export

pipx install tbc-video-export

(There is also self contained builds if install issues arise)

Optional dependencies for GPU (Nvidia Cards) FLAC compression support:

sudo apt install make ocl-icd-opencl-dev mono-runtime

Build VHS-Decode & LD-Tools Suite

The vhs-decode respository also has hifi-decode, cvbs-decode & ld-decode included.

Download VHS-Decode:

git clone https://github.com/oyvindln/vhs-decode.git vhs-decode

Install VHS-Decode:

cd vhs-decode

Build and install vhs-decode via pipx

pipx install .

Compile and Install ld-tools suite: (Required)

mkdir build2
cd build2
cmake .. -DCMAKE_BUILD_TYPE=Release -DUSE_QT_VERSION=5
make -j4
sudo make install

Go back to the main directory with

cd .. 

To update do git pull while inside of the vhs-decode directory. To update to the latest git version of vhs-decode/ld-decode/hi-fi decode, run pipx install . inside the vhs-decode directory after running git pull To update the tools to the latest version, the steps under "Compile and Install ld-tools suite: (Required)" has to be re-ran after a git pull. The tools are not updated very often.

Note: debian/ubuntu does not have a qt6 version of qwt in repositories as of yet so you have to inform the build script to use Qt5 if both qt5 and qt6 are installed with -DUSE_QT_VERSION=5 as it might otherwise try to compile with qt6 instead and failing to locate qwt. The option is otherwise not needed.

Legacy Buidling

(to be added)

Older builds may have use for testing or understanding older functiontions.
