# VLC Media Player (Inter Digital VLC VTM Decoder Plugin installation of Windows and Linux)
This can work only for VLC 3.0.9.2 and later version (e.g., 3.0.17.4). VLC 4.0.0-dev or below than version 3 won't work.

To install Inter Digital VLC VTM Decoder Plugin, you need VLC Media Player latest version installed on your computer and supported 64-bit.

Step 1: Copy libvtmdec.dll and libvvcdecoder_plugin.dll into your VLC Media Player folder following folder: VLC/plugins/codec

C:\Program Files\VideoLAN\VLC\plugins\codec

Step 2: Copy libvvctsdemux_plugin.dll into your VLC Media Player folder following: VLC/plugins/demux

C:\Program Files\VideoLAN\VLC\plugins\demux

Step 3: Enjoy and play your h266 file into your VLC Media Player :).

### For Linux users

Open terminal and copy code:
```
sudo cp libvvcdecoder_plugin.so libvtmdec.so /lib/x86_64-linux-gnu/vlc/plugins/codec
sudo cp libvctsdemux_plugin.so /lib/x86_64-linux-gnu/vlc/plugins/demux
```

VLC from Snap Store:
```
sudo cp libvvcdecoder_plugin.so libvtmdec.so /snap/vlc/2344/usr/lib/vlc/plugins/codec
sudo cp libvctsdemux_plugin.so /snap/vlc/2344/usr/lib/vlc/plugins/demux
```

# Build VLC InterDigital Plugin

Explanation of CMAKE names:

VLC_INCLUDE_DIR = Includes of VLC SDK Plugins

VLC_LIB_DIR = Libs of VLC SDK

VLC_PROGRAM_DIR = VLC Program directory

VTMDEC_LIB_NAME = Name title of libvtmdec

VTM_DIR = libvtmdec source files

VLC_SRC_DIR = VLC Source files of the desktop version

DVBPSI_DIR = DVBPSI source files

### Windows

You need the CMAKE GUI, Visual Studio 2017 or newer, [VLC SDK Win64 3.0.9.2](https://download.videolan.org/pub/vlc/3.0.9.2/win64/) or [latest version](https://download.videolan.org/pub/vlc) (choose zip or 7z only), VLC source files .tar.xz, [libvtmdec](https://vcgit.hhi.fraunhofer.de/delagrangep/VVCSoftware_VTM/-/tree/VTM-22.2-MT) precompiled shared dll in lib folder + sources, dvbpsi source and VLC source files of the desktop version. You need to modify vlc_threads.h, before compile.

vlc_threads.h can be found in VLC folder/sdk/include/vlc/plugins. Search `val = poll(fds, nfds, timeout);` and comment the only one file, that's it.

Build Decoder Plugin, see screenshot of CMAKE GUI:

Before building TS demuxer plugin, please download source code of VLC 3.0.9.2 or latest version following .tar.xz file container and decompress to vlc-3.0.9.2/src or latest version like example vlc-3.0.2.0/src:

https://download.videolan.org/pub/vlc/3.0.9.2/vlc-3.0.9.2.tar.xz

For latest version, you need to find latest version by looking ascending:

### Linux

You need CMAKE GUI, build-essentials, VLC SDK (you have to get from Windows build of 7z or zip compressed file that contains `sdk/lib` and `sdk/include` folders), [libvtmdec](https://vcgit.hhi.fraunhofer.de/delagrangep/VVCSoftware_VTM/-/tree/VTM-22.2-MT) sources, dvbpsi source and VLC source files of the desktop version. You need to modify vlc_threads.h, before compile.

Please double-click downloaded compressed file and decompress VLC Windows SDK build to anywhere folder for example "~/vlc-3.0.9.2" or you can use CLI like 7-Zip `7z x vlc-3.0.9.2-win64.7z -o$HOME`.

vlc_threads.h can be found in VLC folder/sdk/include/vlc/plugins. Search `val = poll(fds, nfds, timeout);` and comment the only one file, that's it.

![vscodethelinecommentvlcthreads](https://user-images.githubusercontent.com/88035011/175109219-6ea70dc4-b696-4045-a071-ef1306bc9634.png)

libvtmdec build:
Compiled file could be found in lib folder in libvtmdec.

```
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j
```

Before build Decoder Plugin, you need to find libvlccore in Linux.

### Option 1 (recommended):

To find libvlccore, you can simply install VLC by your package distribution like apt, pacman or Snap.

Most Linux package version can be found libvlccore:

```
/usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0
```

On Snap store version, the latest version of VLC can be found, but the numbers are different:

```
/snap/vlc/3777/usr/lib/libvlccore.so.9.0.1
```

If you can't find it, you can find libvlccore on `/` folder.

```
sudo find / -type f -name 'libvlccore.so*'
```

You can pick Linux package or Snap version, if unsure pick Linux package standalone or only that you installed on Linux package or Snap version.

Once you've found, 

### Option 2 (optional):

If you don't want to find libvlccore and you don't want to get libvlccore installed on Linux package or Snap package, you can build source code of VLC shipped inside libVLC. 

Instructions can be found there of LibVLC:

https://wiki.videolan.org/LibVLC#Compiling

If option one or/and two didn't work, you can create issue to [VLC Forums](https://forum.videolan.org) or/and VVCEasy, so the VLC community or I/we can help you to solve your problem.

dvbpsi build requires of TS Demuxer Plugin:

```
./bootstrap
./configure --enable-release
make -j
sudo make install
```

Original documentation must be in the original repository: https://github.com/InterDigitalInc/VTMDecoder_VLCPlugin

### Alternative using command line of Windows

Open Windows Terminal/Windows Command Prompt, make sure you do cd of C:/Users/(put your username)/Downloads/VVCEasy/VLC

Copy code following:
```
copy libvtmdec.dll "%programfiles%\VideoLAN\VLC\plugins\codec" 
copy libvvcdecoder_plugin.dll "%programfiles%\VideoLAN\VLC\plugins\codec"
copy libvvctsdemux_plugin.dll "%programfiles%\VideoLAN\VLC\plugins\demux"
```

Note to VLC 4.0.0-dev users:

The VVC video file cannot loaded by newest version of VLC 4.0.0-dev, because it is nightly build and it's unstable.

For more information about VLC 4.0.0-dev see: https://www.theverge.com/2021/2/12/22279750/vlc-4-0-new-user-interface-videolan-media-player-video-music-movie-database-web-player

I tried to build two DLL files on VLC 4.0.0 SDK, but the compiler failed, so you must use VLC 3.0.9.2 or latest of VLC 3 version branch.
