Audio, I don't *think* so. At the very least, Vista and 7 allow you to |
| 29 |
configure whether or not applications are allowed to take exclusive |
| 30 |
control over a device. |
| 31 |
|
| 32 |
Video inputs, yes. |

That actually makes for a really good argument to use something like |
| 41 |
PA's ALSA wrapper when you can't do without Flash. I hear recent |
| 42 |
versions of Flash support PA directly. |
| 43 |
|
| 44 |
I can see an argument for Flash wanting control over A/V hardware; |
| 45 |
audio and video recorders have been implemented in it. Flash, IME, |
| 46 |
doesn't grab A/V until a Flash applet access them, but it also doesn't |
| 47 |
let them go. Perhaps their internal VM is poorly defined such that |
| 48 |
it's OK for apps to assume that once they have a resource, it's always |
| 49 |
there, and they're stuck maintaining that VM model for compatibility. |
