GStreamer gst-rtsp-server广电 / 酒店行业标准,本来以为在AI这么发达的情况下小白搭建一个将udp/rtp转为rtsp的服务应该不难但实际上都快被整疯的节奏。记录一下。需求由于iptv酒店项目需要多个机顶盒播出同步而只有rtsp才可以的。故广电设备比如编码器卫星接收机输出的udp/rtp流需要经过服务器转为rtsp流基本就能同步播出的了。由于自身能力有限最终只能播出udp转的rtsp流。推流软件UdpTsAnalyser_1.61.exe发送地址udp://239.94.0.31:5140,推送的广电常用的mpeg2格式的音视频流ts流。环境搭建1.ubuntu20.04太新太旧也是一堆错误能正常运行后地址为192.168.11.2122.进入/root/gst-build/gst-rtsp-server/examples目录vlc播放地址rtsp://192.168.11.212:8554/test1推本地流./test-mp4 --port 8554 4.mp4或者./test-launch --port 8554 filesrc location4.mp4 ! qtdemux ! h264parse ! rtph264pay namepay0 pt962udp不转码直接封装**********udp不卡顿*****最终工业级无卡顿、超低延迟命令推荐直接用这个 UDP-TS 转 RTSP./test-launch --port 8554 \udpsrc port5140 multicast-group239.94.0.31 do-timestampfalse buffer-size1048576 \! tsparse set-timestampsfalse \! queue leaky2 max-size-buffers0 max-size-bytes0 max-size-time100000000 \! rtpmp2tpay namepay0 pt96这个vlc播放是流畅的。由于我们要播放多个节目那我们重写test-launch.c的代码root目录下建立my_rtsp_server目录1.频道地址配置文件ch.conf239.94.0.31:5140239.94.0.32:5140239.94.0.33:5140239.94.0.34:5140239.94.0.35:5140239.94.0.36:5140239.94.0.37:5140239.94.0.38:5140239.94.0.39:5140239.94.0.40:51402.main.c文件可以读取频道配置文件#include gst/gst.h#include gst/rtsp-server/rtsp-server.h#include stdio.h#include stdlib.h#include string.h#define DEFAULT_RTSP_PORT 8554#define CHANNEL_FILE ch.confstatic char *port (char *)DEFAULT_RTSP_PORT;static GOptionEntry entries[] {{port, p, 0, G_OPTION_ARG_STRING, port,RTSP server port (default: 8554), PORT},{NULL}};typedef struct {char ip[50];int udp_port;} Channel;int read_channels(Channel channels[], int max) {FILE *f fopen(CHANNEL_FILE, r);if (!f) {g_printerr(Cannot open %s\n, CHANNEL_FILE);return -1;}int count 0;char line[128];while (fgets(line, sizeof(line), f) count max) {memset(channels[count], 0, sizeof(Channel));char clean_line[128] {0};int j 0;for (int i 0; line[i] ! \0; i) {char c line[i];if ((c 0 c 9) || c . || c :) {clean_line[j] c;}}if (strlen(clean_line) 5) continue;char *colon strchr(clean_line, :);if (!colon) continue;*colon 0;strcpy(channels[count].ip, clean_line);channels[count].udp_port atoi(colon 1);count;}fclose(f);return count;}int main(int argc, char *argv[]) {GMainLoop *loop;GstRTSPServer *server;GstRTSPMountPoints *mounts;GOptionContext *optctx;GError *error NULL;Channel channels[20] {0};int channel_count, i;optctx g_option_context_new(- UDP to RTSP Server);g_option_context_add_main_entries(optctx, entries, NULL);g_option_context_add_group(optctx, gst_init_get_option_group());if (!g_option_context_parse(optctx, argc, argv, error)) {g_printerr(Option error: %s\n, error-message);g_error_free(error);return -1;}g_option_context_free(optctx);gst_init(argc, argv);loop g_main_loop_new(NULL, FALSE);server gst_rtsp_server_new();g_object_set(server, service, port, NULL);mounts gst_rtsp_server_get_mount_points(server);channel_count read_channels(channels, 20);if (channel_count 0) {g_printerr(No channels\n);return -1;}for (i 0; i channel_count; i) {char mount_path[128] {0};char pipeline[512] {0};GstRTSPMediaFactory *factory gst_rtsp_media_factory_new();snprintf(mount_path, 127, /iptv/%s:%d, channels[i].ip, channels[i].udp_port);snprintf(pipeline, 511,udpsrc port%d multicast-group%s do-timestampfalse buffer-size1048576 ! tsparse set-timestampsfalse ! queue leaky2 max-size-buffers0 max-size-bytes0 max-size-time100000000 ! rtpmp2tpay namepay0 pt96,channels[i].udp_port, channels[i].ip);gst_rtsp_media_factory_set_launch(factory, pipeline);gst_rtsp_media_factory_set_shared(factory, TRUE);gst_rtsp_media_factory_set_latency(factory, 0);gst_rtsp_mount_points_add_factory(mounts, mount_path, factory);g_print(✅ OK: rtsp://0.0.0.0:%s%s\n, port, mount_path);}g_object_unref(mounts);gst_rtsp_server_attach(server, NULL);g_print(\n RTSP server running on port %s\n, port);g_main_loop_run(loop);return 0;}3.编译gcc main.c -o main pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0不报错生成main执行文件即可4.运行./main大概会显示rootlinux:~/my_rtsp_server# ./main?
