IP 摄像头的 FFmpeg RTSP 问题

发布于 2024-10-28 21:53:13 字数 2157 浏览 6 评论 0原文

我下载了 FFmpeg Windows 二进制文件，并成功地将 ffplay.exe 用于媒体文件和一些支持 RTSP 的 Ip 摄像机（例如 Acti）。

我在 Bosch( h264) NDC 265 P 相机上尝试 ffplay ，但不起作用。当我使用调试选项启动 ffplay 时，我得到以下信息：

我可以使用 VLC 播放器播放博世 IP 摄像机...但不能使用 FFmpeg...

那么

ffmpeg 不支持 H264 吗？

原文

I download FFmpeg windows binary and use ffplay.exe successfully for media files and some Ip Cameras with RTSP support (eg Acti).

I try ffplay on a Bosch( h264) NDC 265 P camera it does not work. When i start ffplay with debug option i get folllowing

I can play Bosch IP camera with VLC Player...But can not with FFmpeg...

Does ffmpeg not support H264?

在尝试使用 ffplay（版本 0.10）播放来自 Bosch DINION HD 摄像机的 H.264 流时，遇到了同样的问题。

问题的根本原因在于 SDP 中的有效负载类型不正确：

m=video 0 RTP/AVP 35
a=rtpmap:35 H264/90000

博世设备在 pt 值 35 而不是正常的动态范围上发送数据是常见情况。
只需删除 h264/mpeg4 和 h263 (de)payloader 中的 pt 即可获得对博世的支持。

还有与此问题相关的几个相关问题：

另一组博世设备也发现了同样的情况：博世 DINION HD 720p IVA、博世 DINION NBN-498-P IVA、博世 NTC-255-PI、博世 VIP X1600 XFM4。

Got the same issue with H.264 stream from Bosch DINION HD camera on attempt to play it with ffplay (version 0.10).

The root cause of your problem is in the incorrect payload type in SDP:

m=video 0 RTP/AVP 35
a=rtpmap:35 H264/90000

Looks like that's common case for Bosch devices to send out their data on pt value 35 instead of the normal dynamic range.
Just remove the pt in the h264/mpeg4 and h263 (de)payloaders and you will have support for Bosch.

As well several related issues for this problem:

Same was found for set of another Bosch devices: Bosch DINION HD 720p IVA, Bosch DINION NBN-498-P IVA, Bosch NTC-255-PI, Bosch VIP X1600 XFM4.
