Hello, After some research on v4l2 and videbuf2, and considering that easycap driver is pretty outdated I've decided to start writing a new driver from scratch. I am using the excellent vivi driver and some usb video capture drivers as a starting point. And of course, I'm using the current easycap implementation as a reference (it works pretty well). I have a couple of doubts regarding the development itself (how to trace properly, where to allocate urbs, and such) but perhaps the maintainers prefer to take a look at the code. However, currently the driver is just a skeleton: it does all v4l2 and videobuf2 intialization but it doesn't actually stream video or submit urbs. So, 1. Should I try to have something more finished before submit or can I submit as it is? 2. In any case, how should I submit it? (Considering there is already a working driver).
Have you considered instead slowly moving the existing easycap driver over to all the new infrastructure we have now. For starters replace its buffer management with videobuf2, then in another patch replace some other bits, etc. ? See what I've done to the pwc driver :) OTOH if you already have a new more modern driver ready, then I say go ahead and submit it. I would suggest to add it to staging too, and make the 2 kconfig options conflict, so enabling one would allow the user to no longer select the other (with a note about this in the help text). And then hopefully soon we will see a follow up patch removing the old driver, and then moving the new one out of staging. Which ever path you choose: Thanks for working on this!
