Support for video is a good idea and I'm all for it.
Actually, there was a project long ago to include it in the player, using a custom flash-based player which would allow overlaying AA-style buttons to control the video and all - there was a basic prototype by lukegb but in the end it was kind of dropped. In fact I've never been too thrilled about using custom Flash-based solutions as I don't know Flash myself, so my stance is to do all that can be done in JS, and rely on well maintained external libraries for the rest (like the Soundmanager2 library I use for playing sounds and music).
Anyway, back on the subject : I'm all for implementing support for videos, but it requires a fair bit of planning
First, you need to clarify the scope of what you want to implement. "support for video tags" in which circumstances ?
- Video as a type of page in the evidence "check" data ?
That's definitely the simplest part.
- Displaying videos on the top screen ?
If so, how ? Video playing on the whole top screen, or video behaving like a background, with potentially characters and so on overlayed ?
- Presenting a video, and a specific part of the video ?
That's the most interesting feature I think, but the toughest to implement.
Anyway, I suggest that you open a new topic on this subject, and clarify the scope of what you wish to do based on these questions - and whatever more comes to your mind
Of course here I mention use cases in the player : don't forget to start thinking about how this would be integrated in the editor as well.
EDIT : oh, and no specific reason for Quick Reply, it's just disabled by default on new forums and I always forget to turn it on. It should be ok now.
