Bitstream Mode3 Videoparser

The following repository consists of a video parser that can extract video statistics without decoding pixel information from a given video file. Here, statistics refer to higher mode statistics, considering e.g. motion, block sizes, QP values, ...

For a direct application of this videoparser, please check out the ITU-T P.1204.3 Reference Implementation.

If you use this videoparser in any of your research work, please cite the following paper:

Requirements (Native Linux)

You can also use Docker, see the Docker guide.

To build the videoparser on a Linux system (e.g. Ubuntu 18.04/20.04) you need the following main requirements:

Python 3
scons build system
gcc

All requirements can be installed with the following commands:

sudo apt-get update -qq
sudo apt-get -y -qq install python3 python3-numpy python3-pip git scons autoconf automake build-essential libass-dev libfreetype6-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev yasm
pip3 install --user --upgrade pip
pip3 install --user pandas

For Ubuntu 22.04, you may need to apply a patch to FFmpeg:

cd ffmpeg && patch -p1 < ../mathops.patch

If you want to run the parser under Windows, please check out the Development guide.

Building

To finally build the parser, either run:

./build.sh

Or, manually run:

# Configure, Build and Install ffmpeg
cd ffmpeg && ./configure_ffmpeg.sh && make -j $(nproc) && make install

# Build videoparser Application and libvideoparser
cd ../VideoParser && scons

Usage

To run the parser, call:

./parser.sh <video>

For help, see ./parser.sh --help:

usage: parse.py [-h] [--dll DLL] [--output OUTPUT] input

Bitstream Mode 3 Video Parser

positional arguments:
  input            input video

optional arguments:
  -h, --help       show this help message and exit
  --dll DLL        Path to DLL (default: ../VideoParser/libvideoparser.so)
  --output OUTPUT  Path to output JSON stats file, a file extension of
                   .json.bz2 will compress it; if None report filename will be
                   automatically estimated based on video name (default: None)

2017--2020

Troubleshooting

If something is not working, please run:

./testmain.sh <video>

It will open a GDB run of the main video parser library. Type run and check if something breaks.

Docker

If you want to use the videoparser in a Docker container, you just need Docker installed on your system. Go to the Docker website to install it.

Pre-built Docker image

We provide a pre-built Docker image on GitHub Container Registry. You can use it without building it yourself.

To pull the image, you need to have a valid GitHub token with access to the repository. If you don't have a token, create one here, and make sure it has read:packages scope enabled.

docker login ghcr.io

You will be prompted to enter your GitHub username, and as password, enter your personal access token. Once you have a token, you can pull the image, and rename it to videoparser for easier use.

docker pull ghcr.io/telecommunication-telemedia-assessment/bitstream_mode3_videoparser:master
docker image tag ghcr.io/telecommunication-telemedia-assessment/bitstream_mode3_videoparser:master videoparser

Building the Docker image yourself

⚠️ The Docker container is tested to work on Linux AMD64. If you are using a different architecture, you might run into errors. Specifically, we have observed issues building the container under Apple Silicon Macs.

To build the image yourself, clone this repository and run:

docker build -t videoparser .

Running the Docker image

Then, to run the parser, assuming you have a video file input.mp4 in your current directory, run:

docker run -it --rm -v $(pwd):/tmp videoparser /tmp/input.mp4 --output /tmp/output.json.bz2

This will create a output.json.bz2 file in the current directory too.

Note that /tmp is the working directory inside the container, not on your host.

Development

To further add new codecs or measures, please see development.md.
