Nuo Mi 40a14ef970 avcodec/executor: remove unused ready callback Due to the nature of multithreading, using a "ready check" mechanism may introduce a deadlock. For example: Suppose all tasks have been submitted to the executor, and the last thread checks the entire list and finds no ready tasks. It then goes to sleep, waiting for a new task. However, for some multithreading-related reason, a task becomes ready after the check. Since no other thread is aware of this and no new tasks are being added to the executor, a deadlock occurs. In VVC, this function is unnecessary because we use a scoreboard. All tasks submitted to the executor are ready tasks.		2024-10-04 21:58:42 +08:00

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.
