Recent versions of TenFourFox can use your Power Macintosh's camera or QuickTime-compatible video or audio device to upload photos and video (securely, of course! -- you will always be asked). You can see if your device works with our user media test page (don't worry, your images and audio are never uploaded).
However, it is not possible to support all devices. In general, most audio devices will work, but video devices that do not export a standard 640x480 video image and are not IIDC or QuickTime compatible will not work. Some IIDC-compatible FireWire cameras may send a non-standard image, for example, despite being otherwise compliant. These will generate a scrambled image in TenFourFox.
Built-in audio (through the line-in/microphone port) is supported on all supported Macintosh models and is always available. USB audio should work, but has not been tested.
If you have multiple devices connected, the FireWire devices take precedence, and not all devices may appear. See issue 221.
It may be possible to get certain USB webcam devices working with the macam driver (available separately). While we can't necessarily support these ourselves, we'd like to know if they at least do work. Other USB video sources may not be compatible. Again, if they don't work with QuickTime, they will almost certainly not work with TenFourFox.
Please post working and non-working devices in the comments. We will try to support as many devices as reasonably possible within technical constraints.
