avTranscoder

C++ API for Libav / FFmpeg

Based on Libav/FFmpeg libraries to support various video and audio formats, avTranscoder provides the high level API to re-wrap or transcode media easily.

What you need to know

• C++ library
• Java and Python bindings generated with SWIG
• multiplateform (Linux, MAC, Windows)
• your call to be based on Libav, FFmpeg, or your custom fork of one of these librairies

How to use

Check out applications contained in the project to see examples of how to use the library in C++, Java or Python.

To encode, avTranscoder manipulates profiles. A profile is a text file which discribes, with a set of key-value, what we want as output for the format, the video, or the audio. You can create your own profiles and export a variable called AVPROFILES to indicate the path to them.

The minimum format profile is:

avProfileName=profileName
avProfileLongName=profileLongName
avProfileType=avProfileTypeFormat
format=formatName 

The minimum video profile is:

avProfileName=profileName
avProfileLongName=profileLongName
avProfileType=avProfileTypeVideo
codec=codecName
pix_fmt=pixelFormat
r=frameRate

The minimum audio profile is:

avProfileName=profileName
avProfileLongName=profileLongName
avProfileType=avProfileTypeAudio
codec=codecName
sample_fmt=sampleFormat
