pvrXp bin # ivtv-ctl --get-yuv-mode Unable to switch to user DMA YUV mode pvrXp bin # echo $? 1
In the first example we see that the return code is greater than zero which is good But I would think it should be possible to query the state of the ioctl while loopback is enabled pvrXp bin # ivtv-ctl -K0 ioctl IVTV_IOC_PASSTHROUGH ok pvrXp bin # ivtv-ctl --get-yuv-mode ioctl VIDIOC_G_FMT ok Current yuv_mode 4 Interlaced pvrXp bin # echo $? 0 pvrXp bin # ivtv-ctl -K1 ioctl IVTV_IOC_PASSTHROUGH failed: Device or resource busy pvrXp bin # In the second example we see that querying the yuv mode succeeded but we can't enable looback afterword. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
