How do I test if the current driver support a specific kind of field type? The device I'm working with seems to work only in interlaced mode. V4L2_FIELD_NONE is ignored. From v4l-info: video capture VIDIOC_ENUM_FMT(0,VIDEO_CAPTURE) index : 0 type : VIDEO_CAPTURE flags : 0 description : "Packed YUY2" pixelformat : 0x56595559 [YUYV] VIDIOC_G_FMT(VIDEO_CAPTURE) type : VIDEO_CAPTURE fmt.pix.width : 720 fmt.pix.height : 576 fmt.pix.pixelformat : 0x56595559 [YUYV] fmt.pix.field : INTERLACED fmt.pix.bytesperline : 1440 fmt.pix.sizeimage : 829440 fmt.pix.colorspace : SMPTE170M fmt.pix.priv : 0 Is it a module driver limit or an hardware limit? In Windows it seems ok... I don't think VLC ( I use it for testing on Win ) de-interlace automatically. Ideas? I have to de-interlace myself the frames I suppose...
