video is distorted when captured in flash player #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
run v4lsink with a video test source

$sudo v4lsink 'videotestsrc ! V4l2SinkLoopback'

When viewed in mplayer by connecting to the loopback device everything
looks normal (see mplayer-test-signal.png)

I have included an swf for testing, run

$ flashplayer webcam.swf

When captured using Abode flashplayer 10 the image is very distorted (see
flashplayer-test-signal.png)

When flash connects directly to the build it web cam on /dev/video0 the
picture is OK, when running /dev/video0 though v4lsink and then accessing
the virtual device (/dev/video1) in flashplayer the same distortions are
apparent, so this is not isolated to the videotestsrc.

I do not have flashplayer in debian, so it is difficult to test if this bug 
also true
for current svn code.

can you test this on version from svn? svn have some bugfixes, so maybe problem 
is
solved there.

if svn is ok - I can make fixed version for 2.6.28 kernel.

I mean v4l2loopback, of course. likely that loopback is the source of the 
problem.

Ok, I will try that when I can, currently I am away and have a super slow 
connection.

Hi I am back...

To install v4l2loopback  from svn do I need to upgrade to 2.6.29 kernel ?

yes, you need.

if you do not find aready built deb with 2.6.29 you always can use make-kpkg to 
build
one.
