Smart-Vcutter

A multiplatform tool to generate small, silent and short clips from videos.

Attention: The sound support is not necessary to this project. The focus is to produce video animations instead of GIF images. I hope gif format get out of the internet some day.

It was a prototype (spike) and needs lots of code improvements, i'm opening the code to get some help with that.

Features

• Extract a smaller area from video frame.
• Rotation, Scale, Translation support.
• Reverse video playback.
• h-264, h-265, mjpeg, webm codecs support
• First/Last frame comparation tool.
• Interpolation support.
• User friendly interface.
• Multiplatform.

Example of a generated video clip:

Generate and build the project

cmake .
cmake --build .
the test will run after the command above

Generate and build clearing first

cmake .
cmake --build . --clean-first
# the test will run after the command above

Install

cmake .
cmake --build .
sudo make install

Run the tests

make test
# or
make CTEST_OUTPUT_ON_FAILURE=1 test

Coverage

cmake -DCMAKE_BUILD_TYPE=Debug .
make coverage
# you can replace firefox browser if you want to
firefox coverage/index.html

Windows building

# It's necessary mingw
# The project was successfully compiled with: gcc.exe (i686-posix-dwarf-rev2, Built by MinGW-W64 project) 6.3.0
cmake -G "MinGW Makefiles" .
mingw32-make

If you are a developer and want to colaborate

• Turn the functions smaller.
• Remove repeated code.
• Refactory complex code.
• Rename functions and variables to make the project easy to understand.
• Create documentations.
• Add tests when it's possible.
