Framework driver metadata channels

Hello,

I would like to make a framwork driver that has 64 metadata channel. The metadata would be added in heaps, and could be days after the metadata was created.

So just wondering if there are:

-Any limitations with the number of metadata channels on the framework driver?

-Can I have multiple metadata channels with bounding boxes and text attached to a single video channel?

-Can I have several metadata channels attached to video channels on different hardware?

-Would a framework driver with no video channels still require a license to run? (whatabout in futur versions?)

-Could there be any issues with playback when adding metadata to a channel with non-sequential timestamps. i.e. adding blocks of metadata anywhere in the timeline in any order.

I am sorry but many developers are out of office due to Easter. We will get back to you as soon as possible. Sorry for the inconvenience.

  1.  No limitation.

  2.  Yes.

  3.  Yes. It doesn’t have to be the same hardware. For a video device you set the Related Metadata and this is what governs the “relation”.

  4.  Yes, it does. I believe a device on driver framework even if having no video channel will require one license.

  5.  It has to be sequential timestamps. This is a limitation of the underlying media database.

Ok, so I can add one block before another block as long as all the frames in the block have sequential timestamps? I will try this out soon…

Edit: Oh so by sequential you mean there is no way to insert metadata in the timeline if any data has an older timestamp? This part is very important can you please elaborate?

repeat from another thread ..

Metadata is used to save data associated with the video, especially frequent/continues data. The data gets stored with the video in the same highly optimized database. One limitation that the database imposes is that data must come into the database in a chronologically correct order, in other words you cannot enter data that is older than the newest record.
