Bug 389471 – gst-plugins-ffmpeg fails to load due to TEXTRELs

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description onox 2011-11-04 04:36:35 UTC]

First of all, I _have_ installed a boatload of gst-plugins-*, including -ffmpeg, -xvid, -x264, -vp8:

[I] media-plugins/gst-plugins-ffmpeg (0.10.12(0.10)
[I] media-plugins/gst-plugins-vp8 (0.10.22(0.10)
[I] media-plugins/gst-plugins-x264 (0.10.18(0.10)
[I] media-plugins/gst-plugins-xvid (0.10.22(0.10)

Problem is that when I use gst-launch-0.10 or totem, it cannot display xvid and h264 video's. webm video's _are_ displayed.

For example, for h264, Totem says:

** Message: Missing plugin: gstreamer|0.10|totem|H.264 decoder|decoder-video/x-h264, stream-format=(string)avc, alignment=(string)au, level=(string)2.1, profile=(string)baseline (H.264 decoder)

Rebuilding (once again) gst-plugins-ffmpeg, gives:

 * TEXTREL usr/lib/gstreamer-0.10/libgstffmpeg.so
 * TEXTREL usr/lib/gstreamer-0.10/libgstpostproc.so
 * TEXTREL usr/lib/gstreamer-0.10/libgstffmpegscale.so

Furthermore, gst-inspect-0.10 ffmpeg gives:

No such element or plugin 'ffmpeg'

So maybe gst-plugins-ffmpeg is broken. GStreamer used to work long long time (could easily be 2 years) ago. (This bug made me switch to mplayer some years ago) Maybe it's a configuration issue that GStreamer don't know how to lookup some plugins or something (system is a couple of years old; did original stage3 install some years ago) (I don't even whether GStreamer has some configuration files)

After some debugging on IRC, the problem is that the user is running a hardened system and the textrels disallow any gst-ffmpeg bits from being loaded.

When I do:

rm .gstreamer-0.10/registry.i686.bin
gst-launch-0.10 playbin2 uri=file:///path/to/super/top/secret/file

(gst-plugin-scanner:17420): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstpostproc.so': /usr/lib/gstreamer-0.10/libgstpostproc.so: cannot make segment writable for relocation: Permission denied

I even recompiled gst-plugins-ffmpeg with vanilla compiler. Doesn't fix it.

Fixed in 0.10.13-r1.
