[Mp4-tech] H.263 Non-standard Resolution

[Mohit Garg]

Thanks Mario.
Yes. It should move to the nearest multiple of 16. However, my basic doubt
is w.r.t. the resolution given in the container vs. the resolution in the
bitstream. Is there a convention as to what should override the other in
case of a conflict?
regards
Mohit
