Some media data use variable frame rates (e.g. speech coding, video
surveillance, subtitles ...). It would be interesting to have support for that
in MSE. 

In the case of the ISOBMFF, samples can be created with a given duration and
later on, this duration can be extended (e.g. adjusting using tfdt or signaled
using sample flags sample_depends_on=2 and sample_has_redundancy=1)
