Good work, I'm waiting for comments from Nicolas. Nicolas, is the druid also freezing for you with your driver? Actually, all what it is doing is opening the device and closing it 5 times in a row. If it freezes, it could indicate a bug in the driver. That's the purpose of the test actually because many drivers are not stress-tested and the druid is stress-testing them :) Le jeudi 04 novembre 2004 à 01:24 +0100, Heikki Henriksen a écrit : > Hello guys and gals. > > I had some problems getting my really cheap sn9c102-based webcam to > function with the otherwise fine work of Nicola Orru' on pwlib's > V4L2-plugin. > > After some debugging and a (very short) time trying to figure out the > V4L2-API, I found that my cheap camera didn't handle mmap with multiple > buffers.
