Two days ago, the team behind FFmpeg released their latest version of FFmpeg 4.2, nicknamed “Ada”. This release comes with many new filters, decoders, and demuxers.

FFmpeg is an open-source project composing software suite of libraries and programs to handle multimedia files. It has cross-platform multimedia framework which is used by various games and applications to record, convert and stream audios and videos. The previous version FFmpeg 4.1 was released last year in November. The FFmpeg team has announced on Twitter that the follow-up point release (4.2.1) will be released in a few weeks.

FFmpeg 4.2 has a AV1 decoding support through libdav1d. It also supports decoding of HEVC 4:4:4 content in nvdec, cuviddec and vdpau. It has many new filters like tpad, dedot, freezedetect, truehd_core bitstream, anlmdn, maskfun, and more.

PCM-DVD has been included as an encoder in FFmpeg 4.2. It also introduces numerous demuxers such as dhav, vividas, hcom, KUX, and IFV. This version also removes libndi-newtek.

The new version allows the mov muxer to write tracks in any unspecified language. Earlier, a mov mixer could write in only English, by default. The latest version also supports clang to compile CUDA kernels.

Users are happy with the FFmpeg 4.2 release and seem to be excited to get hands on with the new features in their applications.

A user on Hacker News comments, “Massive “thank you” to FFmpeg for being an amazing tool. My app pivotally depends on FFmpeg extracting screenshots of videos for users to browse through.”

Another comment on Hacker News reads, “Nice to see improved HEVC 4:4:4 support in Linux”

Additionally users have appreciated the growth of FFmpeg project in general.

A Redditor comments, “Man ffmpeg is so awesome. It’s still mind blowing that something so powerful is FOSS.

Outside of programming languages, operating systems, and essential tools like the GNU suite, I think an argument can be made that ffmpeg is one of the most important pieces of software ever created.

We live in a digital world and virtually everything from security cameras to social media sites to news stations use ffmpeg on some level”
