Andreas Rheinhardt 4fe91e3676 avcodec/aacps: Move initializing common stuff to aacdec_common.c ff_ps_init() initializes some tables for AAC parametric stereo and some of them are only valid for the fixed- or floating-point decoder, whereas others (namely VLCs) are valid for both. The latter are therefore initialized by ff_ps_init_common() and because the two versions of ff_ps_init() can be run concurrently, it is guarded by an AVOnce. Yet now that there is ff_aacdec_common_init_once() there is a better way to do this: Call ff_ps_init_common() from ff_aacdec_common_init_once(). That way there is no need to guard ff_ps_init_common() by an AVOnce any more. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>		1 year ago

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.
