So if I understand this correctly, then this device can only transmit or receive, but not both at the same time? If that's the case, then I wonder if it isn't enough to let it depend on whether VIDIOC_S_AUDOUT or VIDIOC_S_AUDIO was called last. > Also I've added some things to the ivtv-radio tool. Should I try to > "up-stream" those as well? Perhaps we should take the opportunity to merge this tool as v4l2-radio into the v4l2-apps/util directory of the master v4l-dvb repository. It would be really nice if it can be used to test the transmitter features and RDS receiver as well, i.e. extending and improving this tool. I like having such fairly low-level and easy to debug utilities. They are a great tool to verify the proper functioning of hardware like this.
