Summary: MJPEG files transition problem when using OpenGL
Product: Cinelerra
Version: 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: Medium
Component: Video Display
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I use MJPEG files as "proxy" for HDV editing (see in wiki).
I HAVE to use OpenGL due to hardware scaling ("proxy" scheme assumes
always 1440x1080 project size, and scales "proxy" by e.g. 2.0).
Very annoying is that when using those files, video transitions, in particular
dissolve does not work properly. Compositor goes to black inside the
transition. Video Format YUVA-8. It works with XV display.
Some example files:

http://mk.phys.us.edu.pl/~marcin/movies/mjpeg_opengl_problem.xml
Reproducible: Always
Steps to Reproduce:
1.Open MJPEG file in a project
2.Do some dissolve transition between 2 edits
3.play with Video Output - OpenGL-XV to see the difference.
