If this is supposed to match the actual macroblocks, then this would
have to consider field pictures and interlacing as it differs from
progressive
There is no change on that side, no addition, no change about it, this
code is moved, and interlace is already managed in the current code:
//Stored height
mxf_write_local_tag(s, 4, 0x3202);
avio_wb32(pb, stored_height>>sc->interlaced);
[...]
//Display height
mxf_write_local_tag(s, 4, 0x3208);
avio_wb32(pb, display_height>>sc->interlaced);
The patch disables the rounding for some formats, it is not intended to
change the behavior for MPEG-2 Video and AVC formats as it seems fine
(FFmpeg has the same behavior as other muxers, at least for MPEG-2
Video, also for interlaced content).
