Anton Khirnov b6e7d64394 fftools/ffmpeg: stop using packet pts for decoded audio frame pts If input packets have timestamps, they will be propagated to output frames by the decoder, so at best this block does not do anything. There can also be an arbitrary amount of delay between packets sent to the decoder and decoded frames (e.g. due to decoder's intrinsic delay or frame threading), so deriving any timestamps from packet properties is wrong.		2023-05-02 10:59:24 +02:00

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.
