Adding synchronized metadata to video files, streamed or not

[jgg]

Hi all,

Just an example: While watching a movie through RTSP streaming or playing a local file, in a specific scene appears a car. I would like to show a cars' advertisement in this moment. I think that the best way to achieve it is to add metadata to the file and then process it in some way in the receiver side, just as subtitles.

I would like you to tell me what technologies, software like video editors or ideas you know or have experience with that could help to get this working. Maybe MPEG-7? MPEG encapsulation? Future VLC releases ?

Thanks for your time,
Javi

Mpeg4 part 12 ?

[jgg]

It's a candidate.

Yes, but I don't know if a good standard exists. Ask to the mpeg4 consortium. And then implement it in VLC

Do you know any tool able to add and/or extract any kind of scripts/metadata/additional text to any video/audio container/file such as mp4, mpeg-2 or any other not being proprietary?

This can be done with Windows Media File Editor and Windows' video files:



But I need something working in an open environment, such as VLC

Any suggestion?

mp4 gpac?

[jgg]

Yes, probably with BIFS and VRML support it would be possible through MP4box and Osmio to package and play "marked" streams, but it would let without RTSP support among others. That's why I asked for something more... "widely used" (if possible, but it seems not possible).

Thanks for your answer anyway, I will keep on taking an eye on GPAC.
