24 | /* ivtv knows several distinct output modes: MPEG streaming, | ||
25 | YUV streaming, YUV updates through user DMA and the passthrough | ||
26 | mode. | ||
27 | |||
28 | In order to clearly tell the driver that we are in user DMA | ||
29 | YUV mode you need to call IVTV_IOC_DMA_FRAME with y_source == NULL | ||
30 | first (althrough if you don't then the first time | ||
31 | DMA_FRAME is called the mode switch is done automatically). | ||
32 | |||
33 | When you close the file handle the user DMA mode is exited again. | ||
34 | |||
35 | While in one mode, you cannot use another mode (EBUSY is returned). | ||
36 | |||
37 | All this means that if you want to change the YUV interlacing | ||
38 | for the user DMA YUV mode you first need to do call IVTV_IOC_DMA_FRAME | ||
39 | with y_source == NULL before you can set the correct format using | ||
40 | VIDIOC_S_FMT. | ||
41 | |||
42 | Eventually all this should be replaced with a proper V4L2 API, | ||
43 | but for now we have to do it this way. */ | ||
