Bug 290080 – media-libs/x264-0.0.20090923 breaks media-video/ffmpeg-0.5_p19928

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Diego Elio Pettenò (RETIRED) 2009-10-21 23:00:00 UTC]

See this?

 * QA Notice: Package has poor programming practices which may compile
 *            fine but exhibit random runtime failures.
 * libavcodec/libx264.c:75: warning: implicit declaration of function ‘x264_nal_encode’

Now see the random runtime failure:

Why's that?

flame@yamato x264-snapshot-20090923-2245 % fgrep -c x264_nal_encode /usr/include/x264.h
0

flame@yamato x264-snapshot-20090923-2245 % fgrep x264_nal_encode common/common.c
 * x264_nal_encode:
int x264_nal_encode( uint8_t *dst, int b_annexb, x264_nal_t *nal )

flame@yamato ffmpeg-0.5 % fgrep x264_nal_encode libavcodec/libx264.c 
        int s = x264_nal_encode(p, &size, 1, nals + i);

Do you see something different? . . . yes! The number and type of parameters don't match even the slightest!

Have fun…

Why mixing arch and ~arch? 

Should be using ffmpeg-0.5_p19928.

I guess the best course of action is to restrict the x264 dep in the stable FFmpeg to avoid more people mixing their systems.

[Comment 2 Diego Elio Pettenò (RETIRED) 2009-10-22 09:39:30 UTC]

Uh no my mistake, let me doublecheck on _p* sources, I checked -r1 sources but indeed I have _p* installed (no mix, pure ~amd64).

+  22 Oct 2009; Samuli Suominen <[e-mail]> ffmpeg-0.5-r1.ebuild:
+  Fix media-libs/x264 depend wrt #290080, thanks to Diego E. 'Flameeyes'

flame@yamato ffmpeg-0.5_p19928 % fgrep x264_nal_encode libavcodec/libx264.c
            if(x264_nal_encode(x4->sei, &x4->sei_size, 1, nals + i) < 0)

even worse :D

media-libs/x264-0.0.20091021 causes the following packages to fail to emerge here.

media-video/ffmpeg-0.5_p19928 
media-libs/libquicktime-1.1.3 
media-video/mplayer-1.0_rc4_p20090919-r2 
media-video/transcode-1.1.4

Error is always to do with a missing element named "b_bframe_pyramid" (sorry for German output):

0.0.20090923 is now gone from tree, and the deps are adjusted. 
also, new snapshot is available, for both x264 and ffmpeg.
