ffmpeg - RTP Stream 显示灰色背景然后崩溃

转载作者：行者123 更新时间：2023-12-04 23:23:41

我正在尝试使用 opencv 和 SDP 文件在 python 中播放一些 RTP 流。我得到一个灰色窗口，顶部有一些扭曲的图像(见附图)，几秒钟后程序会崩溃，灰色窗口会关闭。

output

我还尝试通过wireshark捕获流的数据包并使用媒体信息提取视频信息。

注意:提取的视频播放流畅。

capture

使用GSpot的媒体信息

another

SDP 文件包含:

v=0
m=video 5000 RTP/AVP 103
c=IN IP4 239.194.115.71
a=rtpmap:103 H264/90000

这些是终端中显示的错误代码:

Python代码:

vcap = cv2.VideoCapture('test.sdp')

while (1):
    ret, frame = vcap.read()
    cv2.imshow('VIDEO', frame)
    cv2.waitKey(1)

Wireshark 转储:

我是否在 SDP 文件中使用了错误的编解码器代码或时钟速率才能正确显示流？

最佳答案

确保视频流以 SPS、PPS 开头。你可以在wireshark中检查这个。(如果可以的话，分享wireshark转储)

首先启动您的 python 脚本，然后从实时摄像头开始流式传输。

这将确保您不会错过网络摄像机的任何初始帧。
