gst-libs/gst/tuner/tunerchannel.h: - add a freq_multiplicator field to make the conversion between internal frequency...
Original commit message from CVS: * gst-libs/gst/tuner/tunerchannel.h: - add a freq_multiplicator field to make the conversion between internal frequency unit and Hz * sys/v4l/gstv4lelement.c: * sys/v4l2/gstv4l2element.c: - change default video device to /dev/video0 * sys/v4l/v4l_calls.c: * sys/v4l2/v4l2_calls.c: - we only expose frequency to the user in Hz instead of bastard v4lX unit (either 62.5kHz or 62.5Hz)
