[Closed] What free (or low cost) FLV or MP4 player for embedding into a web page?

Normally this would be simple because there are plenty of tools like JWPlayer, FlowPlayer etc that do the trick. However, the commercials behind them work out fine if you just do web development, i.e. stuff connected to one or more domains. But we don't - we build online training that gets delivered in many different ways, hence the cost of using commercial players like those above is prohibitive to the customer.

So, can anyone recommend a solid player that's either free or has a more adaptable commercial license? Or can someone build one for us?

Cheers
