[英]RTSP tunneled HTTP, FFMPEG
I'm trying to stream from an Axis ip camera which uses RTSP over HTTP. 我正在尝试从使用RTSP over HTTP的Axis ip camera流式传输。 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.
我可以使普通的RTSP流工作,但是我找不到有关如何为流实际设置隧道模式的任何信息或文档。 It is supported in the source code by setting the control_transport to RTSP_MODE_TUNNEL .
通过将control_transport设置为RTSP_MODE_TUNNEL,源代码支持它。 My question is simple how do I do this with the following code?
我的问题很简单,如何使用以下代码执行此操作?
int ret = avformat_open_input(&pFormatCtx, [@"rtsp://ip/axis-media/media.amp" UTF8String], NULL, NULL);
I tried the following: 我尝试了以下方法:
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);
But it simply ignores it for me (It still keeps using RTP). 但它只是忽略了它(它仍然继续使用RTP)。 I tried this aswell
我试过这个
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;
How would I solve this? 我该如何解决这个问题? I'm thinking it's something really simple since the ENUM is there.
我认为这很简单,因为ENUM就在那里。
Working solution is 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);
did you try this 你试过这个吗?
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);
