Jetson Nano 已经安装了 GStreamer,但是,nVidia 并没有完成配置, include 路径需要自己在配置一下才行。方法如下:
在 /etc/profile 文件最后添加以下两行内容即可:
export C_INCLUDE_PATH=/usr/include/gstreamer-1.0:/usr/include/glib-2.0:/usr/lib/aarch64-linux-gnu/glib-2.0/include:$C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH=/usr/include/gstreamer-1.0:/usr/include/glib-2.0:/usr/lib/aarch64-linux-gnu/glib-2.0/include:$CPLUS_INCLUDE_PATH
保存后重启系统,即可。用下面的程序(文件名 basic-tutorial-1.c )测试一下:
#include <gst/gst.h>
int
main (int argc, char *argv[])
{
GstElement *pipeline;
GstBus *bus;
GstMessage *msg;
/* Initialize GStreamer */
gst_init (&argc, &argv);
/* Build the pipeline */
pipeline =
gst_parse_launch
("playbin uri=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm",
NULL);
/* Start playing */
gst_element_set_state (pipeline, GST_STATE_PLAYING);
/* Wait until error or EOS */
bus = gst_element_get_bus (pipeline);
msg =
gst_bus_timed_pop_filtered (bus, GST_CLOCK_TIME_NONE,
GST_MESSAGE_ERROR | GST_MESSAGE_EOS);
/* Free resources */
if (msg != NULL)
gst_message_unref (msg);
gst_object_unref (bus);
gst_element_set_state (pipeline, GST_STATE_NULL);
gst_object_unref (pipeline);
return 0;
}
用下面的命令编译:
gcc basic-tutorial-1.c -o basic-tutorial-1 `pkg-config --cflags --libs gstreamer-1.0`
运行编译好的程序,应该能看到来自 https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm一段很有趣的视频。

本文介绍了如何在Jetson Nano上安装并配置GStreamer的include路径,通过编辑/etc/profile文件添加环境变量。然后提供了一个简单的C程序(basic-tutorial-1.c)来测试GStreamer的功能,该程序从指定URL播放视频。编译程序使用`gcc`并链接GStreamer库。成功执行后,系统将播放来自https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm的视频。
