Streaming secretly: FFmpeg 8 now enables real-time subtitling of videos
The FFmpeg project, an essential tool in the world of multimedia, has released its eighth major version, codenamed "Huffman." This new update brings a host of improvements and exciting new features, making it a significant milestone for the open-source software.
One of the standout additions in FFmpeg 8.0 is the integration of Whisper, an automatic speech recognition model. This integration, contributed by Georgi Gerganov, allows for automatic subtitles to be incorporated into FFmpeg, providing a more accessible and user-friendly experience.
FFmpeg 8.0 also boasts improved handling of various video formats. Huffman, named after the Huffman code algorithm invented in 1952, has been updated to better support AVP, the Advanced Professional Video format. Additionally, the software now supports VVC (Versatile Video Coding, ITU H.266) using VAAPI, Intel's open spec for GPU acceleration. This means that FFmpeg can now handle VVC inside Matroska container files.
In terms of codecs, FFmpeg 8.0 uses the Vulkan API for hardware acceleration of some codecs, including AV1, FFv1, VP9, and ProRes RAW. This upgrade allows for improved performance and efficiency in video processing.
Moreover, FFmpeg 8.0 can now decode RealVideo 6.0, a format that dates back to at least 2015, and animate displaying JPEG-XL files. It also supports common encryption (CENC) for AV1 files and all types of SCC screen content coding.
The history of the FFmpeg project has been tumultuous, with attempted forks such as LibAV. However, LibAV was abandoned in 2020. Debian, a well-known Linux distribution, switched to LibAV but later returned to FFmpeg for reasons explained by LWN a decade ago.
For a comprehensive list of projects using FFmpeg, one need only look at Wikipedia. The list is eye-opening, showcasing the widespread use and importance of this versatile software.
If you're new to FFmpeg or simply want to learn more about its significance, Drew deVault's article, "In praise of ffmpeg," is highly recommended. It provides an insightful and engaging exploration of the software's capabilities and impact on the multimedia landscape.
In conclusion, FFmpeg 8.0 is a testament to the continuous evolution and improvement of this essential tool. With its new features and enhanced capabilities, it promises to remain a cornerstone of the multimedia world for years to come.
