《FFmpeg Basics—Multimedia handling with a fast audio and video encoder_Frantisek Korbel》介绍
Introductionwelcome to the book that will try to make you familiar with many interesting features of the FFmpegproj cc tIts quality indicates several FFmpeg users：Facebook， the largest social network， handles videos from users with ffmpeg toolGoogle Chrome， popular webbrowser， uses FFmpeg libraries for HTML 5 audio and video supportYouTube， the biggest video sharing website， converts uploaded videos with II mpegThe book's focus is to explain the basic video editing like resizing， cropping， padding， denoising.overlay，ctc.， but included are instructions form or c complex processing and experimentsThe chapter Diital Audio describes howto convert and create audio， advanced sound processing is in thechapters Batch Files and Advanced Techniques.
First stepsThe first step is to download FFmpeg binaries， if not already done， the details are in the first chapter or onthe dedicated website.Many Linux distributions already have FFmpeg tools installed or advanced users cancompile their own binaries.The fist chapter contains basic information about FFmpeg project and howtos impi y the work with itstools.If already familiar with these data or if it looks too technical for the start， you can move to the secondchapter and start to c nter various ffmpeg commands，Please note， that many commands in this book are simplified to illustrate the currently explained featureand some parameters are omitted， especially in conversions， the details are in the chapter ConversionBetween Formats.
