This is a very nice tool, thanks.

Is there a chance that this tool could be extended to be able to modify or insert the full range, color primaries, transfer characteristics, and color matrix flags?

The reason I ask is that there are several consumer-level player devices on the market that have bugs with unflagged H.264 streams. The Western Digital TV, NMT Popcorn Hour A-100, A-110, and A-200 all will render H.264 streams with ITU601 color decoding when the H.264 stream is unflagged, regardless of the resolution. For HD streams, this is incorrect, as the rendering should be with ITU709 color decoding.

If the streams are flagged, then the incorrect color decoding does not occur.

I have several streams made from my own Blu-Rays that are unflagged. It would be most convenient/helpful if I could insert the correct color flags into these streams rather than either 1) reencode from the source, or 2) wait for Western Digital/NMT to issue firmware updates. The bugs have been raised to both companies for over a year, and they have not yet issued firmware updates.
