RTSP隧道HTTP，FFMPEG [英] RTSP tunneled HTTP, FFMPEG

问题描述

我正在尝试从使用RTSP over HTTP的Axis ip摄像机流式传输。
我可以获得正常的RTSP流工作，但是我找不到任何关于如何实际设置流的隧道模式的信息或文档。通过将control_transport设置为RTSP_MODE_TUNNEL，支持源代码。我的问题是简单的如何用以下代码来实现？

I'm trying to stream from an Axis ip camera which uses RTSP over HTTP. I can get the normal RTSP stream to work, but I can't find any information or documentation on how to actually set the tunneling mode for the stream. It is supported in the source code by setting the control_transport to RTSP_MODE_TUNNEL . My question is simple how do I do this with the following code?

 int ret = avformat_open_input(&pFormatCtx, [@"rtsp://ip/axis-media/media.amp" UTF8String], NULL, NULL);

我尝试了以下内容：

pFormatCtx = avformat_alloc_context();
pFormatCtx->priv_data = malloc(sizeof(RTSPState));
RTSPState *rt = pFormatCtx->priv_data;
rt->control_transport = RTSP_MODE_TUNNEL;
int ret = avformat_open_input(&pFormatCtx, [@"rtsp://ip/axis-media/media.amp" UTF8String], NULL, NULL);

但它只是忽略它（它仍然使用RTP）。我尝试过这样的

But it simply ignores it for me (It still keeps using RTP). I tried this aswell

 int ret = avformat_open_input(&pFormatCtx, [@"rtsp://ip/axis-media/media.amp" UTF8String], NULL, NULL);
RTSPState *rt = pFormatCtx->priv_data;
rt->control_transport = RTSP_MODE_TUNNEL;

我该如何解决？我认为这是真的很简单，因为ENUM在那里。

How would I solve this? I'm thinking it's something really simple since the ENUM is there.

工作解决方案是

AVDictionary *opts = 0;
int ret = av_dict_set(&opts, "rtsp_transport", "http", 0);


ret = avformat_open_input(&pFormatCtx, [@"rtsp://ip:80/axis-media/media.amp" UTF8String], NULL, &opts);

av_dict_free(&opts);

推荐答案

你尝试这个

AVDictionary *opts = 0;
    if (usesTcp) {
        int ret = av_dict_set(&opts, "rtsp_transport", "tcp", 0);
    }


    err = avformat_open_input(&avfContext, filename, NULL, &opts);
    av_dict_free(&opts);
