[M4IF Technotes] mpeg4 video elementary stream

[Ramkishor Korada]

Hi,
Are you talking about rectangular objects?
If so, then resolution can be changed in between without putting
videoobjectlayer (VO() also needs to be put).
The bit-rate can be changed in between without any problem as long as VBV
compliance is ensured.
