Problem with RGB output levels #328

Closed GoogleCodeExporter closed 9 years ago

Describe the issue you're having:

Consider this graph:
[LAV splitter-source] -> [LAV Video Dec] -> [FFDshow video (just to resize)] -> 
[Decklink video rend]

Lav is set to output RGB32 only.

With RGB output level set to PC (0-255), decklink sdi output is really messed 
up.
With RGB output level set to TV (16-235), everything is perfect.

With this graph 
[LAV splitter-source] -> [FFDshow video (decode + resize)] -> [Decklink video 
rend]

and ffdshow output set to RGB32 only and output level "Computer monitor 
(0-255)" signal is perfectly fine.

The file used for the test doesn't seem to be corrupted. It plays fine on all 
major players.

How can the issue be reproduced? Sample File?
you need a decklink with sdi output

What version of the product are you using? In which Player?
0.51.3, 0.55.2
both graphstudio and custom application.

Thanks

Try without ffdshow for resizing, it will most likely mess it up, because it 
can't tell the difference between full-range or limited-range RGB.
