50 | ----------- |
51 | ||
52 | This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders | |
53 | this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_FRAME`` | |
54 | control. | |
55 | ||
56 | This ioctl call asks the Video Device to return the number of displayed | |
57 | frames since the decoder was started. | |
