USB Webカメラの解像度一覧を取得する方法
Windows 10上で取得してみます。自分の持っているWebカメラの能力を調べてみると面白いかもしれません。
FFMPEGで取得
ffmpeg の実行ファイルはこちらから取得できます。
http://ffmpeg.org/download.html
デバイス名を取得する
.\ffmpeg.exe -list_devices true -f dshow -i x
取得したデバイス名で、解像度一覧を取得する
例えばロジクールの C922の解像度一覧を取り出すなら、下記のようにして取得できます。
./ffmpeg.exe -f dshow -list_options true -i video="c922 Pro Stream Webcam"
取得例
PS C:\ffmpeg\ffmpeg-20200724-21442a8-win64-static\bin> .\ffmpeg.exe -list_devices true -f dshow -i x
