You say you integrated my comment, but the contents of the patch are
exactly the same.

I integrated James A. comment and fixed patch format.
I think you forgot to git add.
In order to send VP9 tracks with FLV or RTMP, the enhanced RTMP
specification tells that VPCodecConfigurationRecord, a.k.a. vpcC
ISO-BMFF box, must be inserted into a metadata message. However, the
function responsible for generating vpcCs currently returns invalid
boxes, that are lacking the Version and Flag fields, inherited from
FullBox. For some reason, both flags were being added manually in
movenc. This patch fixes the issue.
