Bug 276910 – media-video/mplayer-1.0_rc2_p20090530: on AMD Opteron 2382 (Barcelona, 10h) mencoder produces incorrect videos from single PNG files, independently of the encoder used (tested: lavc, copy), FIXED in the live ebuild mplayer-9999

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Some stupid real name 2009-07-07 10:50:04 UTC]

This is just a note that something is wrong with the current version of MPlayer available in Portage tree, but the live ebuild fixes it. Thus, it might be a good idea to test previous versions of MPlayer or package whatever is in the version control at the moment as the next update. If that is not possible, then we will have to wait for another rc and hopefully the fix explained at the end of this bug report will help someone fix their system temporarily.

Mencoder produces incorrect videos when used with different codecs and encoders, for example when used with

mencoder "mf://*.png" -mf fps=5 -ovc lavc -lavcopts vcodec=msmpeg4v2:vbitrate=10000 -o movie.avi

The result is that the movie oscillates between being dark and bright (original files were simply gnuplot plots with white background), multiple frames are stacked on top of each other, etc. 

However, mplayer plays other (non-mencoder encoded) movies correctly. Thus, there must be something wrong with mencoder in that particular version.

I have not tested other versions, but it seems that the issue has been fixed upstream -- the live ebuild mplayer-9999 works fine and solves the issue. 

FIX: emerge mplayer-9999, i.e. the live ebuild. This can be done by adding a line 

 =media-video/mplayer-9999 ~amd64

to your /etc/portage/profile/package.keywords, and 

 =media-video/mplayer-9999

to /etc/portage/profile/package.unmask, and typing emerge mplayer. If everything is set the live ebuild should be emerged.

Reproducible: Always

Steps to Reproduce:
1. Generate a bunch of PNG files.
2. mencoder "mf://*.png" -mf fps=5 -ovc lavc -lavcopts vcodec=msmpeg4v2:vbitrate=10000 -o movie.avi
3. mplayer movie.avi

Actual Results:  
Movie is incorrectly encoded.

Expected Results:  
Correctly encoded movie.

Thanks for the report. Please include your 'emerge --info' as well, since this could also be a toolchain issue (and the recent mencoder source code doesn't happen to trigger the problem anymore).

That was a while ago, so the difference between what is below and what was then is that the GCC used back then was gcc-4.3.3-r2 and the CFLAGS were -O3 -march=barcelona, i.e. without the GRAPHITE loop optimizations.
