Marton Balint 15d160cc0b avformat/udp: increase the default buffer size of a receiving socket to 384K It is a common mistake that people only increase fifo_size when they experience drops, unfortunately this does not help for higher bitrate (> 100 Mbps) streams when the reader thread simply might not receive the packets in time (especially under high CPU load) if the default 64 KB of kernel buffer size is used. New default is determined so that common linux systems can set this buffer size without tuning kernel parameters. Signed-off-by: Marton Balint <cus@passwd.hu>		2020-01-25 23:16:47 +01:00

libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
