Bug 308375 – AVI video in games-arcade/stepmania-3.9-r2 does not work under ffmpeg-5.0-r1

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Wai Ling 2010-03-07 20:48:15 UTC]

stepmania-3.9-r2 can be compiled against ffmpeg-0.5 just fine.  However, song that include avi video as background will be shown as a black background instead.  After a long investigation, I discovered the problem lies in the pixel format define.  Please find attached for the patch that fix this problem.

Reproducible: Always

Steps to Reproduce:
1.emerge =ffmpeg-0.5-r1
2.emerge =stepmania-3.9-r2
3.play song with avi video background

Actual Results:  
video background becomes black

The colour bit masks are wrong after your patch, they were right for 555.
Also I suspect that 565 should be added instead of replacing 555, though I haven't looked at the surrounding code.
Either way I think it would be better to report this to upstream (note that I am not a Gentoo developer though).

Thanks for the advice.  I have modified the patch to include pixel format 565 instead of replacing 555.  Stepmania 3.9 does not have any maintainer upstream.  I have chatted with the developer on IRC, they think making stepmania-3.9 works is not worth their time, so this is the only sensible place I can put my patches.

Added RGB565 and fixed bit mask.
