Anton Khirnov a996478e8c fftools/ffmpeg: simplify output stream initialization call graph Several places in the code currently call init_output_stream_wrapper(), which in turn calls init_output_stream(), which then calls either enc_open() or init_output_stream_streamcopy(), followed by of_stream_init(), which tells the muxer the stream is ready for muxing. All except one of these callers are in the encoding code, which will be moved to ffmpeg_enc.c. Keeping this structure would then necessitate ffmpeg_enc.c calling back into the common code in ffmpeg.c, which would then just call ffmpeg_mux, thus making the already convoluted call chain even more so. Simplify the situation by using separate paths for filter-fed output streams (audio and video encoders) and others (subtitles, streamcopy, data, attachments).		2023-04-09 15:47:45 +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.

The online documentation is available in the main website and in the wiki.

Examples
