What's the meaning of 'blacklisted' on GStreamer?
我正在尝试交叉编译GStreamer。 版本是1.2.3。 主机PC的操作系统是x86 linux，目标系统的操作系统是MIPSEL linux操作系统。
我成功地为目标设备编译了gstreamer和插件。 并且可以执行

我想知道"列入黑名单"的含义以及我该如何解决这个问题。 如果您需要一些信息来解决此问题，请告诉我。
这是我的GStreamer构建配置。

如果您想确定为什么将这些插件列入黑名单，则可以删除" registry.dat"(运行定位以查找其位置)，然后重新运行gst-inspect，将再次检查这些插件并将其列入黑名单的原因应该打印出来。
将它们列入黑名单的原因可能有多种，如果这样做，您应该将它们找出来。
或者，您也可以运行gst-inspect location_of_the_dynamic_library.so
对于gstreamer 1.8，需要使用其他GST_DEBUG = 4 env var释放gst-inspect-1.0，以查看详细原因(本例中的版本不兼容)：
1 | GST_DEBUG=4 gst-inspect-1.0 /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgst_some_plugin.so |
1 2 3 4 | ...15-20 lines with non-interesting details... 0:00:00.035553207 4287 0x29f93c00 WARN GST_PLUGIN_LOADING gstplugin.c:485:gst_plugin_register_func: plugin"/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgst_some_plugin.so" has incompatible version (plugin: 1.10, gst: 1,8), not loading Could not load plugin file: File"/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgst_some_plugin.so" appears to be a GStreamer plugin, but it failed to initialize |
在我的情况下，由于我构建了kvssink而依赖其他库，因此它被列入了黑名单。而且GStreamer找不到它们。
就像这样：
1 2 3 4 | gst-inspect-1.0 kvssink (gst-plugin-scanner:22): GStreamer-WARNING **: 13:07:28.097: Failed to load plugin '/root/bin/producer/libgstkvssink.so': libproducer.so: cannot open shared object file: No such file or directory (gst-plugin-scanner:22): GStreamer-WARNING **: 13:07:28.204: Failed to load plugin '/root/bin/producer/libproducer.so': libcproducer.so: cannot open shared object file: No such file or directory |
为了确认库问题，我使用了ldd
1 | ldd libgstkvssink.so |
它将列出所有可能在系统中找到的依赖项及其路径。
找不到我的库libcproducer.so和libcproducer.so。
基于为其他可见库指定的路径
1 2 | linux-vdso.so.1 (0x00007ffc3c1a6000) libgstreamer-1.0.so.0 => /usr/lib/x86_64-linux-gnu/libgstreamer-1.0.so.0 (0x00007f064d24d000) |
我只是将缺少的库复制到/ usr / lib / x86_64-linux-gnu /
以我为例：
1 2 | cp libcproducer.so /usr/lib/x86_64-linux-gnu/ cp libproducer.so /usr/lib/x86_64-linux-gnu/ |
然后：
1 | gst-inspect-1.0 kvssink |
打印插件详细信息。
我已解决此问题，这要归功于该线程中的信息：
使用自动工具在gstreamer插件中链接到外部库
我找到了原因。它是GLIB，而不是GStreamer。
要为mipsel构建GLIB，我应该设置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | #Glib 2.42.1 wget ftp://ftp.gnome.org/pub/gnome/sources/glib/2.42/$GLIB.tar.xz tar xf $GLIB.tar.xz cd $GLIB #Build for MIPS echo"ac_cv_func_posix_getgrgid_r=yes"> mips.cache echo"ac_cv_func_posix_getpwuid_r=yes">> mips.cache echo"glib_cv_stack_grows=no">> mips.cache echo"glib_cv_uscore=no">>mips.cache ./configure --prefix=$INSTALL_PATH --host=$HOST --cache-file=mips.cache --build=$BUILD make make install cd .. |
我从这里得到了线索。
