Hi Laurent, The thing is, I am using 2 webcams on 2 different USB ports. I start streaming with the first one at 800x600 at 20fps. Everything works ok.
During this, I try to stream from the second one with "mencoder". I got this error: v4l2: ioctl streamon failed: No space left on device mencoder still runs but skips every single frame. Here what I get from a dmesg: uvcvideo: Failed to query (1) UVC control 10 (unit 2) : -32 (exp. 2). uvcvideo: Failed to submit URB 0 (-28). I must admit I edited one line in your driver, I changed the max URB from 5 to 2 (I know you told me not to :p). But then, I changed it back, I even tried with more URBs and less PACKETs (from 32 to 16), still same error. Do you know how I could solve this space problem?
