openSUSE Leap 15でNVENCを有効にしたffmpegをビルドし、mpeg2-tsのGPUエンコードを行う

Nvidia GPUが存在するLinux環境では、NVIDIAのハードウェアエンコーディング/デコーディング機能であるNVENC/NVDECが利用可能ですが、openSUSEの標準パッケージとして利用可能なffmpegではNVENC/NVDECが有効化されていません。これはNVIDIAのライセンス規約により同機能を有効にしたffmpegのバイナリ再配布が許されていないためです。(おそらくほとんどのディストリビューション添付のffmpegも同じはず）

そこで、ffmpegをソースからビルドし、NVENC/NVDECを使えるようにします

Fuck you, Dropbox!
# Starting October 15, Dropbox has fucked all his CentOS 6 (and many other) users
# by changing OS requirements:
# ----
# We are reaching out to let you know that device(s) which do not meet our new
# operating system requirements have been logged out of the Dropbox desktop
# application. Dropbox has ended support for Ubuntu 13.10 and below, and Fedora 20
# and below.
# ...
# Your device(s) must now be on glibc 2.19 or higher to log back into the Dropbox
# desktop application

Generating iOS P12 / certs without Mac OSX Keychain (on linux, windows, etc)
1) Generate a private key and certificate signing request:
openssl genrsa -out ios_distribution.key 2048
openssl req -new -key ios_distribution.key -out ios_distribution.csr -subj '/emailAddress=me@example.com, CN=Example, C=US'
2) Upload CSR to apple at: https://developer.apple.com/account/ios/certificate/create
- choose Production -> App Store and Ad Hoc
3) Download the resulting ios_distribution.cer, and convert it to .pem format:
