の記事を見つけて。

Sony Camera Remote APIを試してみた。

感謝、感謝！　圧倒的感謝!!

　
これでアクションカムを、外部からシャッター切れるぜ！ライブビューもある！？　
というわけで、最新のFDR-X3000（http://www.sony.jp/actioncam/products/FDR-X3000/）
を買ってきた。

これで勝てる！これでPCからコントロールして思いのままだ！
とか思って、Rubyも、Ubuntu も初心者ががんばった記録です。

まずUbuntu 16.04 LTSをダウンロード

PCにインストール。ubuntuは、LTSじゃないと、やっぱ不安があるよね。

Rubyで動くらしいので

・Ruby2.3.1 + rbenvをインストール。
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

ここからが嵌ってしまったポイント。

Ubuntu のWifiアダプタサポートの問題である。
はじめ、インテル® Dual Band Wireless-N 7260を使用していたのだが
どうにも通信がぶちブチ切れる。ファームやら、ドライバやらやってみたが安定しない。

そこでBUFFALOのWLI-UC-G301Nを購入してみた。
このアダプタ、Ubuntu 16.04では標準で読み込むので刺すだけでOK。
それでも怖いのでsonycam shelf connectで接続する前に、手動で接続してる。

では、気を取り直して、

Sony Camera Remote CLI を試す。

ターミナルを立ち上げて、

①　sonycam shelf add　//まずカメラを追加。

$ sonycam shelf add DIRECT-2HX0:FDR-X3000 Bp8F8WHC wlxcce1d51ab723
Do you want set this camera as default? |y| y
=> 0: SSID      : DIRECT-2HX0:FDR-X3000 
      Password  : Bp8F8WHC 
      Interface : wlxcce1d51ab723

②　sonycam shelf connect　//接続。
（この時は、手動で接続してたが、明示的に必要かと思って実行した。

$ sonycam shelf connect
Camera to connect:
  - SSID     : DIRECT-2HX0:FDR-X3000
  - pass     : Bp8F8WHC
  - inteface : wlxcce1d51ab723

Already connected.
Route added successfully.

③さぁ、シャッターを切るぞ切るぞ！　と思いながら、
sonycam still　を実行。
　しかし痛恨の、(SonyCameraRemoteAPI::APIExecutionError)

$ sonycam still
sudo bash /home/admin/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/sony_camera_remote_api-0.3.1/scripts/connect.sh DIRECT-2HX0:FDR-X3000 Bp8F8WHC wlxcce1d51ab723

んー、何か手順が足りてないのかー？

んー、んー、んー。
・・・

そ、そうだ、Rubyのテストスクリプト

があったはずだ。早速執行してみよう。
gedit　test.rb
に以下をコピペして、カメラのSSID、パス、Wifiインターフェース名を入力してと。

test.rb

require 'sony_camera_remote_api'

# お手持ちのカメラのWi-Fi設定
ssid = "DIRECT-2HX0:FDR-X3000"   # SSID
pass = "Bp8F8WHC"               # Passphrase
interface = "wlxcce1d51ab723"             # 接続に使うインターフェース名

# (1) Shelfインスタンスを生成
shelf = SonyCameraRemoteAPI::Shelf.new ".sonycam.shelf"
# (2) カメラ設定を追加し、接続
shelf.add_and_select ssid, pass, interface
shelf.connect

# (3) Cameraインスタンスを生成
cam = SonyCameraRemoteAPI::Camera.new shelf
# 静止画（一枚）撮影モードに変更
cam.change_function_to_shoot 'still', 'Single'
# 撮影＆画像転送。返り値は保存した画像ファイルの相対パス
filename = cam.capture_still
puts filename            #=> 'DSC_xxxxx.JPG'

さて、コンソールを立ち上げ。

クッソ。
"Smart Remote Control SAK", "2.1.5" ？に、 NoMethodError？

つまり命令がないってこと？　わけがわからないよ。

落ち着け、落ち着くんだ。ここまで何をやってきたか、落ち着いて整理するんだ。

ubuntu 16.04 LTS
ryby 2.3.1
rbenv
gem install sony_camera_remote_api
sonycam shelf add
sonycam shelf connect
sonycam shelf still
クッ、大丈夫、　これまで漏れはないはず・・・。

Initializing camera...

ここで止まり、
Camera initialization finished.
に入らないのが問題なのだ。

ここでAPIが、何をしているのだろうか・・・。

落ち着こう。　他のカメラがあるじゃないか・・・。　

α7Sがあったこれでためそう。　これで自信を取り戻そう。

[基本的な手順は。]

①sonycam shelf add
②sonycam shelf select 1
③sonycam shelf connect
④sonycam still
　
だな、だんだん慣れてきたぞ。

①カメラ追加
admin@admin-ubuntu:~$ sonycam shelf add DIRECT-4oE0:ILCE-7S nvSjVzvk wlxcce1d51ab723
Do you want set this camera as default? |y| n

ハッハハー！　ついにやったぞｯ！！

ついにSONY CAMERA APIが動いた。

動いたぞー

ちなみに電波状況がわるいとすぐこうなるっぽい。

ライブビューも試してみよう。
