None of the two webcams I have: ugen3.2: <Ricoh co. Ltd. product 0x18b0> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (100mA) (this is a UVC 1.0 camera) ugen8.3: <vendor 0x046d product 0x08dd> at usbus8, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA) (looks like it works with zc3xx(4) webcamd driver) Currently trying using chromium 80.0.3987.149 on 11.3-STABLE, never really tried much older versions. A causual grep in the webcamd source code is that only a few cameras support memory-to-memory (M2M) interface. It is even hard to tell which models do support this interface. Is this something that can be added? Or the hardware needs to support it somehow? Or is this a bug in Chromium? (https://bugs.chromium.org/p/chromium/issues/detail?id=948147 seems to be only tangentially related) Marcin --1563967779-724816053-1586285510=:49460 Content-Type: application/pkcs7-signature;
