![]() ![]() ![]() The name of the project is inspired by the MPEG video standards group, together with "FF" for "fast forward", so FFmpeg stands for "Fast Forward Moving Picture Experts Group". Some FFmpeg developers were also part of the MPlayer project. The project was started by Fabrice Bellard (using the pseudonym "Gérard Lantau") in 2000, and was led by Michael Niedermayer from 2004 until 2015. Encoders and decoders for many audio and video file formats are included, making it highly useful for the transcoding of common and uncommon media files.įFmpeg is published under the LGPL-2.1-or-later or GPL-2.0-or-later, depending on which options are enabled. įFmpeg is part of the workflow of many other software projects, and its libraries are a core part of software media players such as VLC, and has been included in core processing for YouTube and Bilibili. Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a Gstreamer-like filtergraph. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects and standards compliance ( SMPTE, ITU).įFmpeg also includes other tools: ffplay, a simple media player and ffprobe, a command-line tool to display media information. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files. Unredistributable if compiled with any software with a license incompatible with the GPL įFmpeg 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. X86, ARM, PowerPC, MIPS, RISC-V, DEC Alpha, Blackfin, AVR32, SH-4, and SPARC may be compiled for other desktop computers webp which you could do with del *.png del *.webp As I said I'm no expert, I had no idea how to do this yesterday, I've a lot to learn, hopefully this thread becomes a entry point for ffmpeg newbs.Various, including Windows, macOS, and Linux ( executable programs are only available from third parties, as the project only distributes source code) webp, look for filename_XXXX.png and use ffmpeg to piece then all together to make "FILENAME.mp4" -r is the fps -crf is quality the lower the better but 15 is very good apparently. for %i in (*.webp) do ffmpeg -r 15 -f image2 -s 1920x1080 -i %~ni_%04d.png -vcodec libx264 -crf 15 -pix_fmt yuv420p %~ni.mp4 my dummy understanding every filename ending. png files "FILENAME_XXXX" it may take a minute when it's done type. webp, process it with anim_dump, name the dumped. for %i in (*.webp) do anim_dump -prefix %~ni_ %~ni.webp my dummy understanding of this is every file that ends. First shift+right click in the folder window, "open powershell window here" with powershell open type cmd press enter to open old school command line, then type this in. webp to a folder, also in that folder I drop in ffmpeg.exe I also need an exe from google's webp library libwebp I need "anim_dump.exe" anim_dump, takes an animated. webp, there may be browser plugins to change formats but I like the simplicity of "right click, save as" so I download a load of. gif with the slideshow plugin but places like now store the files as. gif, but it seems only web browsers support it. Hi all I'm no expert at this by any means but I spent a while looking how to do this and I didn't find a dummies guide anywhere, so here it is.webp is a pretty common online format now replacing. ![]()
