linux環境下用GStreamer實現rtsp取流播放
阿新 • • 發佈:2019-01-11
最近研究Gstream的一些東西分享給大家,通過rtsp進行取流,playbin自行構建鏈路。
環境配置:
Ubuntu16 之後自帶Gstreamer 的庫,可以直接用無需安裝
程式碼編譯執行前需要設定如下環境變數:
export LD_LIBRARY_PATH=/usr/local/lib
export GST_PLUGIN_PATH=/usr/local/lib:/usr/lib/x86_64-linux-gnu/gstreamer-1.0
命令列格式:
一個用於test的rtsp地址:
rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov
gst-launch-1.0 playbin uri=rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov
程式碼形式:
#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=rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov", 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;
}
編譯使用注意:
export LD_LIBRARY_PATH=/usr/local/lib
export GST_PLUGIN_PATH=/usr/local/lib:/usr/lib/x86_64-linux-gnu/gstreamer-1.0
gcc main.c -o main -Wall $(pkg-config --cflags --libs gstreamer-1.0)
