Support for AV to USB

[marakhand]

I'm trying to connect to a VHS to Digital Converter device (like this device) on a Linux.
The device is visible, but there are no characteristics.

foreach (var dev in devices.EnumerateDescriptors()) { Console.WriteLine($"{dev.Name}, {dev.Description}, length={dev.Characteristics.Length}"); }

After a little research, it turned out that this is happening because getting VIDIOC_ENUM_FRAMEINTERVALS does not work.
How can I solve this problem?

FlashCap/FlashCap.Core/Devices/V4L2Devices.cs

Line 127 in 227cca1

return ioctl(fd, Interop.VIDIOC_ENUM_FRAMEINTERVALS, frmivalenum) == 0 ?

You mean that this ioctl always gives error?

Yes.
The line 150 (Console.Write) is unreachable.
