For those who are unfamiliar with FFmpeg should know that this is a free software project It can that allows users to decode, encode, transcode, mux, demux, stream, filter, streaming audio and video, among many other things more.
It is also worth mentioning that the package contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample that can be used by applications. As well as ffmpeg, ffserver, ffplay and ffprobe, which it can be used by end users for transcoding, streaming and playback.

In this new version of FFmpeg 5.1 that is presented, it is highlighted that added support for IPFS decentralized file system and the protocol used with it to bind permanent IPNS addresses, as well as support for the QOI image format as well as support for the PHM (Portable Half float Map) image format.
Another of the changes that stands out in this new version that is presented is that implemented the ability to use the VDPAU API (video decoding and presentation) for hardware acceleration of video decoding in AV1 format.
In addition to that, also added "-o" option to ffprobe utility to output specified file instead of standard output, also added new decoders: DFPWM, Vizrt Binary Image, added new encoders: pcm-bluray, DFPWM, Vizrt Binary Image, added media container packers (muxer): DFPWM and added media container unpackers (demuxer ): DFPWM.

- feedback: redirect the cropped frames to another filter and then merge the result with the original video.
- pixelize: performs the pixelization of the video.
- colormap: reflection of the colors of other videos.
- colorchart: generates a color chart.
- multiply - Multiplies the pixel values of the first video by the pixels of the second video.
- pgs_frame_merge – Merges PGS subtitle segments into one packet (bit stream).
- blurdetect – Detect blurry frames.
- remap_opencl : perform pixel remapping.
- chromakey_cuda - is an implementation of chromakey that uses the CUDA API for speedup.
