FFmpeg simplifies the process of converting video and audio like never before. We now have FFmpeg 6.0 “Von Neumann,” a fresh major release available for download. This release brings a multitude of improvements, including new encoders and decoders, filters, enhancements to the ffmpeg CLI tool, and a change in our release strategy. Additionally, it transforms the approach to releases. With each major release, we will increase the version of the ABI.
FFmpeg
The plan is to release a new major version every year, creating a more structured schedule. Another significant change related to releases involves removing deprecated APIs after three release cycles, coinciding with the next major version upgrade. This streamlined approach means we will have more frequent releases and improved organization. It’s important to note that the RadLight MPC DirectShow Filter is also available on this website.
A variety of new decoders are in the spotlight, including Bonk, RKA, Radiance, SC-4, APAC, VQC, WavArc, and various ADPCM formats. QSV and NVenc now support AV1 encoding. The FFmpeg CLI, often referred to as ffmpeg.c to avoid confusion, has undergone optimization for speed with threading and statistics options. Moreover, it allows for passing filter option values from a file. Numerous new audio and video filters have been introduced, such as adrc, showcwt, backgroundkey, and ssim360, accompanied by a selection of hardware filters. Similarly, you can also find the FFmpeg for Audacity Audio and the RadLight Filter Manager on this website.
This release brings numerous behind-the-scenes changes, including the introduction of a new FFT and MDCT implementation used in codecs (stay tuned for an upcoming blog post on this topic), numerous bug fixes, improved ICC profile handling, enhancements in colorspace signaling, incorporation of optimized RISC-V vector and scalar assembly routines, and several refined APIs, all of which are detailed in the doc/APIchanges file in our repository. Also, take a look at the FFDshow. Some proposed features, like Vulkan enhancements and additional FFT optimizations, are planned for the upcoming minor release, 6.1, aligning with our updated release schedule. Key highlights include. Lastly, you’ll also find the FFDShow MPEG4 Video Decoder.
