After ten months of development, the FFmpeg 5.0 multimedia package is now available, featuring a set of applications and a collection of libraries for handling various multimedia formats (recording, converting, and decoding audio and video formats). The package is distributed under LGPL and GPL licenses, with FFmpeg development being closely aligned with the MPlayer project. The significant version number change reflects substantial modifications in the API and a transition to a new release scheme, under which major new releases will occur annually, while long-term support releases will be made every two years. FFmpeg 5.0 will be the first LTS release of the project. <\/p>\n
Key changes added in FFmpeg 5.0 include: <\/p>\n
\n
A significant cleanup of old APIs for encoding and decoding has been conducted, and a transition to a new N:M API has been executed, offering a unified programming interface for audio and video, as well as separating codecs for input and output streams. All previously deprecated old APIs have been removed. A new API for bitstream filters has been added. Formats and codecs have been separated\u2014media container unpackers no longer embed the entire context of decoders. APIs for codec and format registration have been removed\u2014all formats are now always registered.\n
The libavresample library has been removed.\n
A simpler API based on AVFrame has been added to the libswscale library.\n
Significant improvements have been made to Vulkan graphics API support.\n
Support for hardware-accelerated decoding and encoding of VP9 and ProRes formats has been added using the VideoToolbox API.\n
Support for the LoongArch architecture used in Loongson processors has been added, along with support for SIMD extensions LSX and LASX provided in LoongArch. Specific optimizations for LoongArch have been implemented for H.264, VP8, and VP9 codecs.\n
Support for the Concatf protocol has been added, defining a format for passing a list of resources (\"ffplay concatf:split.txt\").\n
New decoders have been added: Speex, MSN Siren, ADPCM IMA Acorn Replay, GEM (raster images).\n
New encoders have been added: bitpacked, Apple Graphics (SMC), ADPCM IMA Westwood, VideoToolbox ProRes. The AAC encoder parameters have been adjusted for higher quality.\n
New media container muxers have been added: Westwood AUD, Argonaut Games CVG, AV1 (Low overhead bitstream).\n
New media container demuxers have been added: IMF, Argonaut Games CVG.\n
A new parser for the AMR (Adaptive Multi-Rate) audio codec has been added.\n
A payload data packetizer has been added for the transmission of uncompressed video using the RTP protocol (RFC 4175).\n
New video filters:\n
\n
segment and asegment\u2014splitting a single stream with video or audio into multiple streams based on time or frames.\n
hsvkey and hsvhold\u2014replace a portion of the HSV color range in the video with values in shades of gray.\n
grayworld\u2014video color correction using an algorithm based on the gray world assumption.\n
scharr\u2014applying the Scharr operator (a variant of the Sobel operator with different coefficients) to the input video.\n
morpho\u2014allows for the application of various morphological transformations to video.\n
latency and alatency\u2014measures the minimum and maximum filtering delay for a previously applied filter.\n
limitdiff\u2014determines the difference between two or three video streams.\n
xcorrelate\u2014calculates the mutual correlation between video streams.\n
varblur\u2014variable blur applied to video, with the blur radius determined by a second video.\n
huesaturation\u2014applies adjustments of hue, saturation, or intensity to video.\n
colorspectrum \u2014 video stream generation with a specified color spectrum.\n
libplacebo \u2014 used for processing HDR shaders from the libplacebo library.\n
vflip_vulkan, hflip_vulkan, and flip_vulkan \u2014 variations of vertical or horizontal video flip filters (vflip, hflip, and flip) implemented using the Vulkan graphics API.\n
yadif_videotoolbox \u2014 a variant of the yadif deinterlacing filter based on the VideoToolbox framework. <\/ul>\n
New audio filters:\n
\n
apsyclip \u2014 applying a psychoacoustic cut to the audio stream.\n
afwtdn \u2014 suppresses broadband noise.\n
adecorrelate \u2014 applies a decorrelation algorithm to the input stream.\n
atilt \u2014 applies spectral shifting for a specified frequency range.\n
asdr \u2014 determines the distortion of the signal between two audio streams.\n
aspectralstats \u2014 outputs statistics with the spectral characteristics of each audio channel.\n
adynamicsmooth \u2014 dynamic smoothing of the audio stream.\n
adynamicequalizer \u2014 dynamic leveling of the audio stream.\n
anlmf \u2014 applies the least mean squares algorithm to the audio stream. <\/ul>\n<\/ul>\n
