前言:

做音視頻領域相關開發或者二次開發，繞不開的幾個工具，ffmpeg,mediainfo巴拉巴拉。

當然都支持跨平臺，并且很多很好的媒體軟件都能看到他們的影子。

話不多說，開始安裝步驟(這里以centos7為例):

1.查看系統版本

cat /etc/redhat-release

?2.下載所需依賴

wget https://mediaarea.net/download/binary/mediainfo/21.03/mediainfo-21.03.x86_64.CentOS_7.rpm wget https://mediaarea.net/download/binary/libmediainfo0/21.03/libmediainfo-debuginfo-21.03.x86_64.RHEL_7.rpm wget https://mediaarea.net/download/binary/libzen0/0.4.39/libzen-0.4.39.x86_64.CentOS_7.rpm

3.依次安裝

rpm -ivh libzen-0.4.39.x86_64.CentOS_7.rpm rpm -ivh libmediainfo-21.03.x86_64.CentOS_7.rpm rpm -ivh mediainfo-21.03.x86_64.CentOS_7.rpm

4.驗證

mediainfo -i adiao.flac --OUTPUT=XML > test.xml <?xml version="1.0" encoding="UTF-8"?> <MediaInfo xmlns="https://mediaarea.net/mediainfo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://mediaarea.net/mediainfo https://mediaarea.net/mediainfo/mediainfo_2_0.xsd" version="2.0"><creatingLibrary version="21.03" url="https://mediaarea.net/MediaInfo">MediaInfoLib</creatingLibrary><media/><media ref="adiao.flac"><track type="General"><AudioCount>1</AudioCount><FileExtension>flac</FileExtension><Format>FLAC</Format><FileSize>67966343</FileSize><Duration>321.369</Duration><OverallBitRate_Mode>VBR</OverallBitRate_Mode><OverallBitRate>1691920</OverallBitRate><StreamSize>0</StreamSize><Recorded_Date>2018-01-1</Recorded_Date><File_Modified_Date>UTC 2021-06-16 09:32:06</File_Modified_Date><File_Modified_Date_Local>2021-06-16 17:32:06</File_Modified_Date_Local><Encoded_Application>Lavf57.41.100</Encoded_Application><extra><encoded_by>Pro Tools</encoded_by><originator_reference>YD!2nAnHFhcaaaGk</originator_reference><time_reference>287854400</time_reference></extra></track><track type="Audio"><Format>FLAC</Format><Duration>321.369</Duration><BitRate_Mode>VBR</BitRate_Mode><BitRate>1691711</BitRate><Channels>2</Channels><ChannelPositions>Front: L R</ChannelPositions><ChannelLayout>L R</ChannelLayout><SamplingRate>48000</SamplingRate><SamplingCount>15425712</SamplingCount><BitDepth>24</BitDepth><Compression_Mode>Lossless</Compression_Mode><StreamSize>67957944</StreamSize><StreamSize_Proportion>0.99988</StreamSize_Proportion><Encoded_Library>Lavf57.41.100</Encoded_Library></track></media> </MediaInfo>
