Section 8.10 of the SAA7113 data sheet shows 16 data formats. The
interesting one for video is #15 Y:U:V 4:2:2.
Thanks. Perhaps, I should have done my homework.
The EM28xx chip programming might rearrange some data, but I have no

Every USB bridge provides their raw video over isoc in a slightly
different format

In the gspca test tarball (see my site), I merged the spca506 code into
the spca505 for a webcam which may also do analog video capture. The

Yes.
When there is no video, isoc urbs are received with actual length=4.
This is header right?
I'm not sure what you mean by no video. Do you have capture

isoc even if there is no actual video
Hello,
I'm a little lost while writing a driver for an easycap device
(saa7113 capture device).
I have my isoc handler, and the isoc urb flying OK.
I also have the videobuf2 queue setup (or at least I think so), and I understand
I need to call vb2_buffer_done() with a filled buffer.
