We're writing a video class device using XP SP2 built in driver.
(Uncompressed, YUY2, 640x480, in bulk mode)
Is it possible to send the stream header (as video class spec 2.4) at
the beginning of a new frame in a separate packet, without any video
data following in the same packet ?
This is much easier when interfacing to external sensors without any
external FIFO between, we can do that in the idle time between each
frame.
But seems that when we do this, Graphedit shows just a black screen.
When we append some "test" YUY2 data, we see the test image.
But "appending" video data in the same packet would be difficult, when
interfacing to the real sensor (we're using FX2LP in slave fifo mode).
Any experience on this ?
