9 years agomovenc: Reorder entries in the MOVIentry struct, for tigheter packing

movenc: Reorder entries in the MOVIentry struct, for tigheter packing

Originally, sizeof(struct MOVIentry) was 48, after the reordering,
it is 40 in my build configuration.

When writing really long mov/mp4 files, this can make a difference
- this saves a bit over 2 MB of memory per hour of video (down to
10.3 MB per hour from 12.3 MB per hour initially) for a video with
75 packets per second - 25 fps + 50 audio packets (which is the
case for AMR audio).
