PallyCon CLI Watermark Embedder is a command line interface (CLI) based watermark embeder that inserts a watermark on an encoded video file. It runs on a packaging server built by the service site itself, and produces the mp4 original video as two streaming contents with watermark (0 or 1) through watermark embedding and packaging process.
PallyCon CLI Watermark Embedder can be downloaded from the console site after joining PallyCon watermarking service. It consists of the following two modules.
FMembedder: Creates two content files, each marked ‘0’ or ‘1’. For example, when the input content is ‘A.mp4’, it creates ‘A_0.mp4’ and ‘A_1.mp4’. Each of the two generated content can be packaged as DASH / HLS streaming content using PallyCon CLI Packager.
Sample Mixer: A test mixer that combines two mp4 files created by FMembedder into a single mp4 file. If you enter a payload string of up to 7 bytes, it will produce a combined result based on that payload. For actual service scenario, the watermark mixer module running on CDN is used to perform the combination of session information at playback time.
You need the following environment to run the CLI Embedder.
AWS GPU instance performance
- Geforce GTX1050 (Desktop, Pascal) << P2 (Tesla K80) << P3 (Tesla V100), G3 (Tesla M60)
- When using an AWS EC2 instance as a watermark embedding server, we recommend an instance of type P3 or G3 for GPU acceleration.
Follow these steps to install the Intel IPP 2018 library:
If you have existing Intel IPP library installed, it is recommended to re-install it.
Install the GPG key for the repository
sudo apt update sudo apt install apt-transport-https wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB sudo apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
Add the Intel® IPP repository
sudo sh -c 'echo deb https://apt.repos.intel.com/ipp all main > /etc/apt/sources.list.d/intel-ipp.list'
Update the list of the packages
sudo apt update
Install IPP library
sudo apt install intel-ipp-64bit-2018.3-051
Uninstall IPP library (if needed)
sudo apt autoremove intel-ipp-64bit-2018.3-051
Run the following script to install the NVIDIA CUDA toolkit.
wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_9.1.85-1_amd64.deb sudo dpkg -i cuda-repo-ubuntu1604_9.1.85-1_amd64.deb sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub sudo apt-get update sudo apt-get install -y \ linux-headers-$(uname -r) \ cuda
Install the dependency libraries required for CLI embedder to run as follows:
sudo apt update sudo apt install -y \ libbz2-dev \ zlib1g-dev \ libass-dev \ libva-dev \ libvdpau-dev \ libssl-dev
Execute the FMembedder executable file in the ‘bin’ folder in the downloaded archive with the following command.
||Input media filename||
||Output media filename||
||The resulting output will be two files with ‘0’ and ‘1’ marked. (~/demo/output_0.mp4 and ~/demo/output_1.mp4)|
||Access Key for service authorization||
||After joining the PallyCon service, you can check the access key in the integration setting of the console site.|
If an error occurs that is related to the common library path, you must set LD_LIBRARY_PATH in the PATH environment variable. For details, refer to the FMembedder.sh file included in the CLI embedder archive file.
Example 1: to apply NVIDIA HW acceleration encoder(nvenc), use ‘-n’ option
FMembedder -i ~/demo/input.mp4 -o ~/demo/output.mp4 -n --access_key ACCESSKEY_BLAHBLAH
Example 2: to apply NVIDIA HW acceleration encoder(nvenc) and decoder(cuvid), use both ‘-n’ and ‘-c’ options
FMembedder -i ~/demo/input.mp4 -o ~/demo/output.mp4 -n -c --access_key ACCESSKEY_BLAHBLAH
For content that applies both forensic watermarking and DRM, you can package the ‘0’ and ‘1’ version mp4 files generated by FMembedder using PallyCon Packager. Depending on the service’s target platform, the two versions of watermark content are packaged in DASH or HLS format, and delivered to the user in real time through the mixer module of the CDN.
For details on DRM packaging and watermark mixing, please refer to the following guide documents.
Execute the sampleMixer executable file in the ‘bin’ folder of the CLI embedder archive with the following command.
You can create a sample mixed video(output_mix.mp4) with a payload data ‘testmsg’ from the FMembedder output by running the following script.
sampleMixer ~/demo/output_0.mp4 ~/demo/output_1.mp4 ~/demo/output_mix.mp4 testmsg
