FFMPEG Filtergraph Generator

Show & Tell
1

Hello, everyone!

I have created an tiny ffmpeg (complex) filtergraph generator using a s-expression representation, which implements basic checks and character escaping.

However, I find its syntax not very user-friendly, and its behaviour is currently unsafe due to a shortage of necessary checks. Also, the documentation is still in progress.

Contributions and suggestions would be appreciated!

Sure!

Before encoding, ffmpeg can process raw audio and video frames using filters from the libavfilter library. Several chained filters form a filter graph. ffmpeg distinguishes between two types of filtergraphs: simple and complex.

This library is written according to documents listed as follows.
