By pure chance, yesterday we published two articles talking about FFmpeg, one about how to convert audio files to other formats and another to record our desktop screen. Also yesterday, the project launched ffmpeg 4.2, codenamed "Ada", to continue improving a framework that was already very powerful and that allows us to perform many tasks related to video and audio. In fact, a lot of multimedia software is based on it.
The new version has made a total of 35 changes, among which we would highlight the support for the AV1 codec through libdav1d. The new version has arrived eight months after the previous version, a v4.1 that introduced some new features such as support for AV1 in MP4 and Matroska / WebM. As we read in its official statement, below you have "some of the outstanding news" that comes along with the new version.
