我想创建一个 VR，所以我创建了一个 RTSP 服务器来链接到我的 Zedmini。如果我使用 h265 编码器它可以工作，但不好的是 RTSP 只有在我使用 Iphone7 VLC 应用程序或计算机窗口 8 VLC 软件时才有效，我的 Android 手机 huawei p7 Onvifer 应用程序根本无法使用这个 RTSP 地址。我需要为我的项目使用华为 p7，因为我要创建应用程序并链接到这个 RTSP 服务器。

根据我的检查，一些 Android 设备不支持 h265 编码器，所以我决定使用 h264，我已经在谷歌上搜索了好几个星期，但因为找不到使用 h264 的解决方案而感到沮丧。

这是我从 test-readme.c 修改的代码------>

#include <gst/gst.h>

#include <gst/rtsp-server/rtsp-server.h>

int main (int argc, char *argv[]) { GMainLoop *loop; GstRTSPServer *server; GstRTSPMountPoints *mounts; GstRTSPMediaFactory *factory;

gst_init (&argc, &argv);

loop = g_main_loop_new (NULL, FALSE);

/* create a server instance */ server = gst_rtsp_server_new ();

/* get the mount points for this server, every server has a default object

that be used to map uri mount points to media factories */ mounts = gst_rtsp_server_get_mount_points (server);
/* make a media factory for a test stream. The default media factory can use

gst-launch syntax to create pipelines.
any launch line works as long as it contains elements named pay%d. Each
element with pay%d names will be a stream */ factory = gst_rtsp_media_factory_new ();
//working case for streaming video //gst_rtsp_media_factory_set_launch (factory,"( videotestsrc is-live=1 ! x264enc ! rtph264pay name=pay0 pt=96 )");

//working case for external camera //gst_rtsp_media_factory_set_launch (factory,"( v4l2src is-live=1 device=/dev/video1 ! video/x-raw, width=(int)720, height=(int)480 framerate=30/1 format=I420 ! timeoverlay ! omxh265enc ! rtph265pay name=pay0 pt=96 )");

//working case for JX2 camera //gst_rtsp_media_factory_set_launch (factory,"( nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080, framerate=30/1, format=I420 ! nvvidconv flip-method=4 !video/x-raw, width=(int)720, height=(int)480 framerate=30/1 format=I420 ! timeoverlay ! omxh265enc ! rtph265pay name=pay0 pt=96 )");

//Fail or not working case for Zed mini camera testing FOR H264 gst_rtsp_media_factory_set_launch (factory,"(v4l2src is-live=1 device=/dev/video1 ! video/x-raw, width=2560, height=720, framerate=30/1, format=I420 ! nvvidconv !video/x-raw, width=(int)720, height=(int)480, framerate=30/1, format=NV12 ! omxh264enc bitrate=10000000 ! rtph264pay name=pay0 pt=96 )");

//working case for Zed mini camera FOR H265 //gst_rtsp_media_factory_set_launch (factory,"(v4l2src is-live=1 device=/dev/video1 ! video/x-raw, width=2560, height=720, framerate=30/1, format=I420 ! nvvidconv !video/x-raw, width=(int)720, height=(int)480 framerate=30/1 format=I420 ! timeoverlay ! omxh265enc ! rtph265pay name=pay0 pt=96 )");

gst_rtsp_media_factory_set_shared (factory, TRUE); /* attach the test factory to the /test url */ gst_rtsp_mount_points_add_factory (mounts, "/test", factory);

/* don't need the ref to the mapper anymore */ g_object_unref (mounts);

/* attach the server to the default maincontext */ gst_rtsp_server_attach (server, NULL);

/* start serving */ g_print ("stream ready at rtsp://172.16.124.75:8554/test\n"); g_main_loop_run (loop);

return 0; }

此代码适用于流式视频、JX2 摄像头、简单的 USB 摄像头（低端）以及 zedmini 摄像头，但使用的是 h265。我需要使用 h264 运行代码，这里肯定有一些元素遗漏或错误。

gst_rtsp_media_factory_set_launch (factory,"(v4l2src is-live=1 device=/dev/video1 ! video/x-raw, width=2560, height=720, framerate=30/1, format=I420 ! nvvidconv !video/x-raw, width=(int)720, height=(int)480, framerate=30/1, format=NV12 ! omxh264enc bitrate=10000000 ! rtph264pay name=pay0 pt=96 )");
