- now report the pci bus_info in the v4l2 QUERYCAP ioctl instead of the ivtv card number - minor bug fix for IVTV_IOC_S_VBI_MODE: always return the current valid VBI service_set as per V4L2 spec. - Bug fix for IVTV_IOC_G_DRIVER_INFO: could not handle requests from older programs that specified a smaller driver_info struct. - Added the ivtv card number field to driver_info. This used to be in the bus_info field of QUERYCAP, but that's now a proper bus info string. Since the card number is ivtv specific this is a better place for it. - Added a IVTV_IOC_G_STREAM_INFO ioctl to obtain information on a ivtv file handle. In particular it returns the stream type. This is, for now, an internal API. - Added a new utility ivtv-detect which detect all (hopefully) v4l devices and shows which device belongs to which card. Especially useful when you have many ivtv (or other) TV cards and get confused as to which device belongs to which card.
It gives this output on my system with a WinTV PCI card, a PVR150 and a
PVR500:
driver bttv-0.9.15, card BT878 video (Hauppauge (bt878)), bus info

On my other system with a PVR 350 (and an older driver, so the bus info is
still the card number):
