While emerging stepmania, it fails to build. I believe this could be related to FFmpeg changing APIs, but I am not sure myself, as I have not tracked FFmpeg lately. I have previously built stepmania successfully on another system, when I used ffmpeg-0.4.9_p20050226-r5. That version is no longer available in portage, and ffmpeg-0.4.9_p20050226-r3 also fails to build, apparently because of a missing patch specified in its ebuild. However, even with the version of stepmania I have been able to build on my other system, videos have never worked properly, which does not bother me (it actually aids gameplay, that "bug" ("feature"?)). Steps to reproduce: 1) build ffmpeg-0.4.9_p20051216 2) build stepmania (either 3.9_rc3 or 3.9) Actual results: G++ fails with the following: arch/MovieTexture/MovieTexture_FFMpeg.cpp: In member

Note: I have been successful in alleviating the first of the compile errors (at line 331), but I became stuck trying to fix line 363, as it seems the frame_rate and frame_rate_base members have disappeared in recent versions of ffmpeg. emerge --info: see attachment
Created attachment 92144 [details] `emerge --info` for the system on which it fails I couldn't fit emerge --info into the original report, so I'm attaching it here.

Created attachment 92173 [details, diff] Patch to make stepmania-3.9_rc3 build
I have now made it build... see the above patch. It seems the biggest problem was AVStream::codec changing from being an AVCodecContext to an AVCodecContext*. I also had to substitute (float)m_stream->r_frame_rate.den / m_stream->r_frame_rate.num instead of (float)m_stream->codec.frame_rate_base / m_stream->codec.frame_rate, which I am not still completely sure whether or not it is correct. Now it plays the videos, but plays them *much* too fast. I'm thoroughly confused by how video playing works, and I'm out of ideas as to where the bug might be, so I'm going to leave it to someone else to help me with that. Sorry for being completely incompetent with bugzilla, this comment probably should have been with the patch instead of separately... Thanks.
Created attachment 92174 [details, diff] A slightly cleaned patch, still builds. Oops, I left my #include <iostream> in there from when I was attempting to debug the video speed problem... that's the only difference between the two patches.

Can you post this as a unified diff? (diff -U) When I just add this patch using epatch to the ebuild I get errors about that it cant find the file to patch.
Actually I would now suggest to just get rid of this ebuild in favour for the final 3.9 one (that works flawless).
3.9 works for me with ffmpeg 0.4.9_p20060530
