ffpp

A dynamic library written in C++ with API for most of the main tasks with FFmpeg. Much faster for your GUI interfaces than using processes.

Running on Windows.

---

Running on GNU/Linux.

---

Use on Windows

Need Clang: winget install --id=MartinStorsjo.LLVM-MinGW.UCRT -e

1. Download libffppwin

Invoke-WebRequest -Uri "https://bit.ly/libffppwin" -OutFile "libffppwin.rar"

3. Unzip(.rar)

4. Enter the folder

cd .\libffppwin

5. Create basic code, example: main.cpp

#include "ffpp/ffpp.hpp"
#include <memory>

int main(){
  auto ffpp = std::make_unique<FFPP>();
  std::cout << "Duration: " 
    << ffpp->ffpp_info(FFPP_INFO::DURATION, "video.mp4") << '\n';
}

If you want, use this video as an example: video.mp4

6. Build and run:

# PowerShell
pwsh build.ps1 main.cpp # Or more files 

# Or: Windows PowerShell
powershell build.ps1 main.cpp # Or more files

# Or directly
.\build.ps1 main.cpp # Or more files

If Windows Defender prevents it from running, give permission to run the script:

pwsh -ExecutionPolicy Bypass -File build.ps1 main.cpp # Or more files

The build.ps1 script compiles and runs the built binary, the output provides information on the video duration, for example: Duration: 00:00:05

If you want to download libffmpeg, build the dll from scratch, see this file: build-win.md.

On GNU/Linux

Dependencies:

On Arch

sudo pacman -S gcc ffmpeg make cmake pkg-config git

On Debian/Ubuntu/Mint:

sudo apt install build-essential ffmpeg make cmake pkg-config git

Compile and install

Run all command below:

git clone https://github.com/terroo/ffpp
cd ffpp
cmake . -B build
cmake --build build
sudo cmake --install build
# Important pos install
# Similar to this: export LD_LIBRARY_PATH=/usr/local/lib
# But for the entire system:
echo /usr/local/lib | sudo tee /etc/ld.so.conf.d/ffpp.conf
sudo ldconfig

Create basic code, example: main.cpp

#include <ffpp/ffpp.hpp>
#include <memory>

int main(){
  auto ffpp = std::make_unique<FFPP>();
  std::cout << "Duration: " 
    << ffpp->ffpp_info(FFPP_INFO::DURATION, "video.mp4") << '\n';
}

If you want, use this video as an example: video.mp4

6. Build and run:

g++ main.cpp -lavformat -lavcodec -lavutil -lswscale -lffpp
./a.out

Example output: Duration: 00:00:05.

API Examples

Assuming you created the object in heap(auto ffpp = std::make_unique<FFPP>();).

01. Convert MP4 to WMV:

ffpp->ffpp_convert("video.mp4", "new.wmv");

Only converts between video extensions: .mp4, .flv, .wmv and .mov

---

02. Extract frames:

ffpp->ffpp_extract_frames("video.mp4", "my_frames_dir");

.ppm images will be generated in the folder provided: (my_frames_dir/).

---

03. Get information from a video:

std::cout << "Duration: " 
  << ffpp->ffpp_info(FFPP_INFO::DURATION, "video.mp4") << '\n';
std::cout << "Bitrate: " 
  << ffpp->ffpp_info(FFPP_INFO::BITRATE, "video.mp4") << '\n';
std::cout << "FPS: " 
  << ffpp->ffpp_info(FFPP_INFO::FPS, "video.mp4") << '\n';
std::cout << "Audio frequency: " 
  << ffpp->ffpp_info(FFPP_INFO::AUDIO_FREQUENCY, "video.mp4") << '\n';
std::cout << "Resolution: " 
  << ffpp->ffpp_info(FFPP_INFO::RESOLUTION, "video.mp4") << '\n';  

---

04. Cut a video from a time to a certain length:

ffpp->ffpp_cut("video.mp4", "00:00:10", 6, "output.mp4");

The cut starts after 10 seconds of the video and will last 6 seconds.

There will be more features in the API in the future. If you want to submit a PR, feel free!
