ffmpeg rtsp错误:服务器回复中的传输不匹配 [英] ffmpeg rtsp error: Nonmatching transport in server reply

问题描述

我正在使用ffmpeg读取rtsp相机.我收到一个错误消息:ffmpeg rtsp错误:c ++中的服务器答复中传输不匹配"和处理输入时发现无效数据".相机已设置"RTP ES".这是代码.

I'm using ffmpeg to read an rtsp camera. I'm getting an error: ffmpeg rtsp error: Nonmatching transport in server reply" in c++ and "Invalid data found when processing input". The camera has setting "RTP ES". Here's the code.

source_name = "rtsp://192.168.1.108/WESCAM";

// Open the initial context variables that are needed
format_ctx = avformat_alloc_context();    
codec_ctx = NULL;

// Register everything
av_register_all();
avformat_network_init();

//open RTSP camera or h264 file
if (avformat_open_input(&format_ctx, source_name, NULL, NULL) != 0) 
{
    return EXIT_FAILURE;
}

推荐答案

这可能有帮助:

AVDictionary *opts = nullptr;
av_dict_set(&opts, "rtsp_transport", "udp", 0); // here "udp" can replaced by "tcp"
avformat_open_input(&pFormatCtx, rtsp_addr, nullptr, &opts);
...
av_dict_free(&opts);
