Ticket #7104, comment 3
initial v1 1 There's a hitch when writing MOVs. Two hdlr atoms are written. Once, within `mdia` and then within `minf`. The specified handler name is correctly written in the mdia child atom, as can be confirmed with any atom parser, like movdump. But when writing hdlr within minf, the track object isn't passed * and hence the metadata isn't used. So the generic value of `DataHandler` gets written.1 There's a hitch when writing MOVs.

But when writing hdlr within minf, the track object isn't passed on* and hence the metadata isn't used. So the generic value of `DataHandler` gets written. 2 2 3 3 When ffmpeg demuxes a MOV, the minf is processed after mdia and so the handler name metadata key is reset with the generic value.
