Fix/video config

[interim17]

The VideoEncoder avc codecs are failing unless we provide them only even numbers for width and height.

In debugging this I explored the codecs a bit and tweaked a few things, aiming for high quality output with reasonable file sizes:

• using a High profile, level 4 AVC codec: this means better compression features and high resolutions
• defining a high bitrate (relative to codecs capability) but letting bitrateMode be variable to keep file sizes down
• real time latencyMode since we are capturing stream, also keeps sizes down
