Hi, It looks for me, that introduce of VIDIOC_OVERLAY_OLD VIDIOC_S_PARM_OLD VIDIOC_S_CTRL_OLD VIDIOC_G_AUDIO_OLD VIDIOC_G_AUDOUT_OLD breaks binary compatibility not v4l itself, but drivers (for example saa7134). You must recompile program from sources (and first check if there is not older videodev2.h) to get it work. This is because these old ioctls are not implemented in newer drivers and they are not implemented in v4l-compat too. You can't run old binary with new driver. Question: Is this correct ???? Should be implemented these old ioctl in new drivers v4l2 ???
