bmdtools以外にも色々使えるようにしておきたい
Setup
bmdtoolsneeds a recent version of libav installed. In order to build it make sure to have the development headers installed.
Building from source
The common scenario assumes you want to use
x264to encode the video andfdk-aacto encode the audio. You might usex265andopusas well but they are not supported in many container formats.The following instructions assume you want to install everything in
/usr/local.
bmdtoolsのインストールlibavが必要になる。その時に
さらに、
を利用することができる。これに加え、
- alsa audio
を有効にして汎用オーディオ入出力への対応させる。

コンパイラ/ビルド用のソフトウェアの準備
ビルドするために以下のコンパイラを入れる。
libx265のビルドには更に以下のものも必要
ccmake
g++ はGNUの標準的なコンパイラとして、NASM/YASMに関しては以下。
nasmとyasmはどちらもx86の SIMD命令（MMX,SSE,SSE2等）に対応したアセンブラ で、 殆どのケースでこれらの命令を利用した高速化のために使用される。 一昔前にはnasmがこの用途での一人勝ち状態であったが、一時期更新が滞り、 新規命令に対応しなかったことから、リプレースとしてyasmが登場した。その後nasmの更新は再開したが、 yasmに移行してしまったプロジェクトも多いため、用途は同じソフトウェアではあるが、両方インストールしておくのが間違いない。
1.1 What Is NASM?
The Netwide Assembler, NASM, is an 80x86 and x86-64 assembler designed for portability and modularity. It supports a range of object file formats, including Linux and *BSD a.out, ELF, COFF, Mach-O, 16-bit and 32-bit OBJ (OMF) format, Win32 and Win64. It will also output plain binary files, Intel hex and Motorola S-Record formats. Its syntax is designed to be simple and easy to understand, similar to the syntax in the Intel Software Developer Manual with minimal complexity. It supports all currently known x86 architectural extensions, and has strong support for macros.
Yasm is a BSD-licensed assembler that is designed from the ground up to allow for multiple assembler syntaxes to be supported (e.g. NASM, GNU AS, etc.) in addition to multiple output object formats and multiple instruction sets. Its modular architecture allows additional object formats, debug formats, and syntaxes to be added relatively easily.
libx264は処理を高速化するためにnasmを利用しており、 libx265は処理を高速化するためにyasmを利用している。
ccmakeをインストールしていないとlibx265のmake-Makefiles.bashが途中で中断される。
同様にg++をインストールしていないとccmakeの途中で中断される。

NASMのインストール
Index of /pub/nasm/stableより、最新版のNASMをダウンロードする。
xdoc と付いているものはマニュアルなので注意。
2020-05-01 00:23:58 +0000 現在、2.13.01
ダウンロードしたものを解凍し、configureを行う。
$ tar xjvf nasm-2.13.01.tar.bz2
$ cd nasm-2.13.01/
$ ./configure
configure が成功したらmakeでビルド、後にmake installでインストールする。
$ make
$ sudo make install

g++とccmakeのインストール
これらはパッケージのものを利用する。簡単。
sudo apt-get install g++ cmake-curses-gui
誤ったものをインストールした場合
汎用性がある問題なのでページを分けた。
動的リンクエラーを解消する
こちらも同様
ライブラリのインストール
libx264のインストール
stable 版をx264, the best H.264/AVC encoder - VideoLANからダウンロードして解凍する。
$ tar xjvf last_x264.tar.bz2
$ cd x264-snapshot-20171018-2245
In order to quickly compile your libx264, you can type the following commands in your shell:
# cd /my/path/where/i/keep/compiled/stuff # git clone git://git.videolan.org/x264.git # cd x264 # ./configure --enable-static --enable-shared # make # make install # ldconfig
--enable-static --enable-sharedを付けないとライブラリが作成されず、
x264の実行ファイルのみが生成されてしまう。
$ ./configure --enable-static --enable-shared

ALSAのインストール
ALSA support isn’t inherently built into
ffmpeg. You need to have the ALSA development files installed at./configuretime when buildingffmpeg.The
ffmpegconfigure script looks foralsa/asoundlib.handlibasound. If either is missing, it simply won’t build ALSA support into the program.
Short answer
run:
sudo apt-get install libasound2-devbefore attempting to configure and compile ffmpeg or anything where you need alsa support.
Process for resolving similar build dependencies:
Returning to this build/install method:
$ cd /usr/src $ sudo git clone git://source.ffmpeg.org/ffmpeg.git $ cd ffmpeg/ $ sudo ./configure && sudo make && sudo make installthe last line is a compaction of three steps, and the first one is significant as
configureestablishes what optional features the binary will support.It is normal to change system libraries and configuration options and rerun
configuremany times until you are happy with its results.The output you want is “alsa” as a supported indev (and probably outdev.)
./configure ... no alsa .. ./configure --help ./configure --list-indevs ./configure --enable-indev=alsa --enable-outdev=alsa ... no alsa .. so it is not just off by default.. grep alsa configure alsa_asoundlib_h alsa alsa_indev_deps="alsa" alsa_outdev_deps="alsa" enabled_any alsa_indev alsa_outdev && check_lib alsa alsa/asoundlib.h snd_pcm_htimestamp -lasoundthis leads to why configure is not supporting alsa, and looking up asoundlib.h goes here though you could also query the packaging db.
sudo apt-get install libasound2-dev ./configure ... alsa! .. ./make ./ffmpeg -formats |grep alsa ... DE alsa! .. (the D/E columns indicate both directions are working) ./make install
asoundlib.h がないとavconvでALSAが有効にならない。
そして asoundlib.h は libasound2-dev に入っている。
libasound2-dev を探してインストールする。
$ apt-cache search libasound
libasound2-dev - shared library for ALSA applications -- development files
$ sudo apt-get install libasound2-dev

使い方
$ avconv -i /dev/video0 -f video4linux2 -list_formats all
avconv version 12.2, Copyright (c) 2000-2017 the Libav developers
built on Oct 21 2017 23:09:27 with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.5) 20160609
Trailing options were found on the commandline.
/dev/video0: Invalid argument
と怒られたので調べたら
Basic FFmpeg syntax structure is
ffmpeg -<options for input 1> -i input 1 -<options for input 2> -i input 2 -<options for output 1> output1 -<options for output 2> output2
最初にオプションを指定し、最後にインターフェイスを指定するようだ。
