Add --codec-options

Browse source 
Add a command-line parameter to pass custom options to the device
encoder (as a comma-separated list of "key[:type]=value").

The list of possible codec options is available in the Android
documentation:
<https://d.android.com/reference/android/media/MediaFormat>
