Reviewed by Eric Carlson.
Add support for Block containing multiple frames. Previously we would create as
many CMSampleBuffer
as found in the block, but all those samples would have the timestamp of the
Block.
We now accrue the duration of each frame and properly increment the sample's
timestamp accordingly.
Manually verified that file plays okay
