#236 Composite transition inverts colors

[Aslanex]

Seems the Composite transition unintentionally inverts colors of a video clip transitioned to a PNG image. The result can be seen on the screenshots.

Using Kdenlive 0.9.10 with MLT 0.9.8 (own build). On MLT 0.9.6 (own build) is the same bug, while version 0.9.3 (from Kdenlive repository) works correctly.

Please provide the melt command line or very simple XML project to show how to reproduce the problem.

Unable to reproduce using:

melt -profile atsc_1080p_25 \
'Snímek obrazovky pořízený 2015-12-13 21-08-40.png' \
-track some720p.mp4 -transition composite

or

melt -profile atsc_1080p_25 \
'Snímek obrazovky pořízený 2015-12-13 21-08-40.png' 
length=100 some720p.mp4 -mix 25 -mixer composite

Sorry, I'm not able to reproduce the bug. Seems it was caused by an old save or something.
Thanks for the support.

Found the problem again. It seems to be caused by using a wipe file in Composite transition.
However, I am still not sure whether it happens always.

The attached mlt file should reproduce it.

[Dan Dennedy]

Nope, that does not reproduce it. SInce you are building MLT yourself, you should try with git master head.

[Aslanex]

Sorry, what does it mean "git master head"?

git clone https://github.com/mltframework/mlt.git

Ok, seems working with 0.9.9. Let's hope it won't occur again.
