Untested but from a read through, the patch looks good. FlagInterlaced is supported in both Matroska and webM, whereas FieldOrder (a new field from the CELLAR work on Matroska) is only supported in Matroska. IMHO though I think that FlagInterlaced without information on FieldOrder is not so useful and that the webM project should consider adopting FieldOrder as well. I'd prefer to see a patch to webM to consider adding FieldOrder to the format rather than see FieldOrder removed from the webM muxer in FFmpeg.
