Martin, That's excellent! So I can test it with the "wss" binary (plus a little bug fix maybe).
Great! Let's see if my TV can detect it... Cheers Steve On 10/07/07, Martin Dauskardt <[EMAIL PROTECTED]> wrote:
You can use the wss tool from Hans: http://ivtvdriver.org/viewcvs/ivtv/trunk/test/ If you execute "wss 1" it will set the TV to a Zoom-mode (no anarmorph 16:9). You will have to modify the code to get real 16:9 Look at the code: wss = 8 + (atol(argv[1]) ? 3 : 0); if (argc == 3) This leads to wss value 8 (4:3) or 11 (PalPlus Zoom). You need value 7 for anarmorph 16:9 I use the following code for the vdr pvr350-plugin: void cPvr350Device::Set_wss_mode() { struct v4l2_format fmt; struct v4l2_sliced_vbi_data data; fmt.fmt.sliced.service_set = V4L2_SLICED_WSS_625; fmt.type = V4L2_BUF_TYPE_SLICED_VBI_OUTPUT; if (ioctl(fh, VIDIOC_S_FMT, &fmt) != 0) { esyslog("pvr350: Set VBI mode failed\n"); } if (ioctl(fh, VIDIOC_G_FMT, &fmt) != 0) { esyslog("pvr350: VIDIOC_G_FMT failed\n"); } data.id = V4L2_SLICED_WSS_625; data.line = 23; data.field = 0; data.data[0] = wss_data; data.data[1] = 0; if (wss_data == 7) { printf("pvr350: set wss mode 16:9 (anarmorph)\n"); } if (wss_data == 8) { printf("pvr350: set wss mode 4:3\n"); } write(fh, &data, sizeof data); } You must open the device before you can use the code above: fh = open("/dev/vbi16",O_WRONLY); Your application must set wss==7 if it detects Does it help you?
