#configure(hash) ⇒ Object

Configures the transcoding using a nested hash with the following format:

config = {:video => { ... }, :audio => { ... }

The keys for the “video” hash can be any of the following: bitrate, codec, cbr, crop, deinterlace, framerate, height, keyframe_interval, maxbitrate, par, profile, passes, stretch, width.

The keys for the :audio hash can be any of the following: codec, bitrate, channels, samplerate.
