ffmpeg 推流c++源码
以下是一个使用DeepStream SDK在C语言中推流的基本示例代码。在此示例中,我们将从视频文件中读取帧,并将其传输到RTSP服务器上。
```c
#include <stdio.h>
#include <string.h>
#include <gst/gst.h>
#include <gst/rtsp-server/rtsp-server.h>
#define VIDEO_SOURCE "filesrc location=/path/to/video.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw(memory:NVMM),format=NV12 ! nvv4l2h264enc ! rtph264pay name=pay0 pt=96"
#define VIDEO_CAPS "application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,sprop-parameter-sets=(string)\"Z0LgHtoCgK8WgA\\,aM48gA\\=\\=\",payload=(int)96"
int main(int argc, char *argv[]) {
GMainLoop *loop = NULL;
GstRTSPServer *server = NULL;
GstRTSPMountPoints *mounts = NULL;
GstRTSPMediaFactory *factory = NULL;
/* Initialize GStreamer */
gst_init(&argc, &argv);
/* Create a new main loop */
loop = g_main_loop_new(NULL, FALSE);
/* Create a new RTSP server */
server = gst_rtsp_server_new();
/* Get the RTSP server's mount points */
mounts = gst_rtsp_server_get_mount_points(server);
/* Create a new RTSP media factory */
factory = gst_rtsp_media_factory_new();
/* Set the media factory's properties */
gst_rtsp_media_factory_set_launch(factory, VIDEO_SOURCE);
gst_rtsp_media_factory_set_shared(factory, TRUE);
gst_rtsp_media_factory_set_protocols(factory, GST_RTSP_LOWER_TRANS_UDP | GST_RTSP_LOWER_TRANS_TCP);
/* Set the media factory's capabilities */
GstCaps *caps = gst_caps_from_string(VIDEO_CAPS);
gst_rtsp_media_factory_set_caps(factory, caps);
gst_caps_unref(caps);
/* Mount the media factory to the RTSP server */
gst_rtsp_mount_points_add_factory(mounts, "/test", factory);
/* Start the RTSP server */
gst_rtsp_server_attach(server, NULL);
/* Run the main loop */
g_main_loop_run(loop);
/* Clean up */
g_object_unref(mounts);
g_object_unref(server);
g_main_loop_unref(loop);
return 0;
}
```
在此示例中,我们使用`GstRTSPServer`和`GstRTSPMediaFactory`类来设置RTSP服务器和媒体工厂,然后将媒体工厂挂载到RTSP服务器上。`VIDEO_SOURCE`和`VIDEO_CAPS`变量定义了我们要使用的GStreamer管道和视频流的属性。在此示例中,我们使用`filesrc`元素从文件中读取视频帧,然后使用`nvv4l2h264enc`元素对视频进行编码,并将其封装为RTSP流。
请注意,此示例仅适用于NVIDIA Jetson平台和安装了DeepStream SDK的系统。如果您使用其他平台或其他软件组件,您可能需要调整`VIDEO_SOURCE`和`VIDEO_CAPS`变量以适应
