2.8.22 was released on 2023-10-29. It is the latest stable FFmpeg release from the 2.8 release branch, which was cut from master on 2015-09-05. Amongst lots of other changes, it includes all changes from ffmpeg-mt, libav master of 2015-08-28, libav 11 as of 2015-08-28.
Thanks to a major refactoring of the ffmpeg command-line tool, all the major components of the transcoding pipeline (demuxers, decoders, filters, encodes, muxers) now run in parallel. This should improve throughput and CPU utilization, decrease latency, and open the way to other exciting new features.
A new major release, FFmpeg 6.0 "Von Neumann", is now available for download. This release has many new encoders and decoders, filters, ffmpeg CLI tool improvements, and also, changes the way releases are done. All major releases will now bump the version of the ABI. We plan to have a new major release each year. Another release-specific change is that deprecated APIs will be removed after 3 releases, upon the next major bump. This means that releases will be done more often and will be more organized.
New decoders featured are Bonk, RKA, Radiance, SC-4, APAC, VQC, WavArc and a few ADPCM formats. QSV and NVenc now support AV1 encoding. The FFmpeg CLI (we usually reffer to it as ffmpeg.c to avoid confusion) has speed-up improvements due to threading, as well as statistics options, and the ability to pass option values for filters from a file. There are quite a few new audio and video filters, such as adrc, showcwt, backgroundkey and ssim360, with a few hardware ones too. Finally, the release features many behind-the-scenes changes, including a new FFT and MDCT implementation used in codecs (expect a blog post about this soon), numerous bugfixes, better ICC profile handling and colorspace signalling improvement, introduction of a number of RISC-V vector and scalar assembly optimized routines, and a few new improved APIs, which can be viewed in the doc/APIchanges file in our tree. A few submitted features, such as the Vulkan improvements and more FFT optimizations will be in the next minor release, 6.1, which we plan to release soon, in line with our new release schedule. Some highlights are:
The next part of the project was to extend the code to be able to accept several clients, simultaneously or consecutively. Since libavformat did not have an API for that kind of task, it was necessary to design one. This part was mostly completed before the midterm and applied shortly afterwards. Since the ffmpeg command-line tool is not ready to serve several clients, the test ground for that new API is an example program serving hard-coded content.
If you are thinking on participating in OPW as an intern, please take a look at our OPW wiki page for some initial guidelines. The page is still a work in progress, but there should be enough information there to get you started. If you, on the other hand, are thinking on sponsoring work on FFmpeg through the OPW program, please get in touch with us at o...@ffmpeg.org. With your help, we might be able to secure some extra intern spots for this round!
Since the splitting of Libav the Debian/Ubuntu maintainers have followed the Libav fork. Many people have requested the packaging of ffmpeg in Debian, as it is more feature-complete and in many cases less buggy.
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects and standards compliance (SMPTE, ITU).
This guide focuses on the encoder x264. It assumes you have ffmpeg compiled with --enable-libx264. If you need help compiling and installing see one of our compiling guides. See HWAccelIntro for information on supported hardware H.264 encoders.
While -preset chooses the best possible settings for you, you can overwrite these with the x264-params option, or by using the libx264 private options (see ffmpeg -h encoder=libx264). This is not recommended unless you know what you are doing. The presets were created by the x264 developers and tweaking values to get a better output is usually a waste of time.
You may need to use -vf format=yuv420p (or the alias -pix_fmt yuv420p) for your output to work in QuickTime and most other players. These players only support the YUV planar color space with 4:2:0 chroma subsampling for H.264 video. Otherwise, depending on your source, ffmpeg may output to a pixel format that may be incompatible with these players.
FFmpeg module for Node. This library provides a set of functions and utilities to abstract commands-line usage of ffmpeg. To use this library requires that ffmpeg is already installed (including all necessary encoding libraries like libmp3lame or libx264)
But, it would not preview, and I think would have failed in the end. To solve that I double clicked on the ffmpeg file and also went into System Preferences, Security & Privacy, and in the General tab I gave permission for ffmpeg to open:
He does give alternate locations for where the file goes. In the folder you used it will be ok for SketchUp 2018, where I put it would work for all versions of SketchUp. Also, you only need the ffmpeg file, all of the other files, and the folder itself (ffmpeg-20200106-1e3f4b5-macos64-static) are not needed.
After build it complained about missing libavdevice.so.60 on first try(ffmpeg --encoder) - I found it in the libavdevice subfolder of your git pull. After that it comlained about all the rest of the common libs being missing one by one. simple guess would be that I didnt install ffmpeg. after adjusting my LD_LIBRARY_PATH for testing ffmpeg loads.
Tiny attachment: I had installed a current mpp, however that got installed into /usr/local/lib and the system mpp was used instead. turns out your ffmpeg isnt compatible with the mpp that comes from radxas repo. a simple override using LD_LIBRARY_PATH fixed that issue, and the segfault is gone. Might be worth adding that to the wiki.
as I just edited, I had mpp built from git, but it was installed to /usr/local/lib so ffmpeg tried to use the radxa-supplied one. Overriding that with LD_LIBRARY_PATH=/usr/local/lib fixed the issue, and i am doing a first test transcode. So far, at least ffmpeg seems to adhere to the requested bitrate, unlike the one from jjm2473 - fps is 70 for 1080p mp4 input and hevc output
woah, it is always amusing me how everyone is using ffmpeg differently, i will try to ask mpp people if they could expose this information. I could actually do it myself but it would be quite ugly and not future maintainable.
@mo123 it plays fine on my setup, my ffmpeg is totally different than yours but drm prime part should be the same. Do you have this for every file, can you send me a sample vid that you have this issue. And are you on 3588 or something else?

I have a video clip recorded by a smartphone vertically, and I'm trying to rotate it 90 degrees clockwise using the usual ffmpeg command (because some players fail to read the EXIF rotation data and display it properly by autorotating). Its EXIF metadata includes "Width: 848; Height: 480; Rotation: 90"Normally, this command should do it:
It seems ffmpeg is also taking into account the original file's EXIF metadata "Rotation: 90" and autorotating before the re-encoding process.So, at the end I've managed to write a script which can be incorporated into the context menu of file managers like Dolphin, Nautilus, Thunar, etc. to rotate the video according to its EXIF rotation metadata, keeping EXIF timestamps, and copying EXIF GPS information - with the help of @Gyan
- when using ffmpeg in a workflow (bash), I get "[22:27:01.911] ERROR: 0 Record and Transcribe[Run Script] /Users/henrikpetersen/Library/Caches/com.runningwithcrayons.Alfred/Workflow Scripts/F0EC9245-15A1-413D-BCD3-9D2A1FF7C06E: line 24: 19662 Abort trap: 6 $FFMPEG_PATH -f avfoundation -i ":0" -t 5 -loglevel verbose "$RECORDINGS_DIR/$FILENAME" 2>&1"
I have tried uninstalling and reinstalling ffmpeg and I have tried uninstalling all of the packages related to pocketsphinx, but they are reinstalled when I install ffmpeg. I'm not sure why it links to pocketsphinx but I can't get ffmpeg to do anything at all. When I use lddtree it looks like libavfilter is using libpocketsphinx.
