Hi all.
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...
Thanks in advance.
