We really need this kind of approach for DASH. One of examples, qtdemux does
not support track_id change in case of MPEGDASH Representation switching. There
is no restriction about track_id change on DASH spec., except for the case that
bitstreamSwitching attribute was set true.

For that reason, we cannot support this mpd
http://vm2.dashif.org/livesim-dev/testpic2_2s/Manifest.mpd

Not only that case, other boxes such as trex should be parsed again per moov.
Since this report is quite old, can I report new patchset on top of the latest
code?
