gst_rtsp_client's Issues

接收RTSP流正常，但是有3-4秒的延时

我用jetson nx接收两路RTSP 2K视频流，接帧很稳定，但是接收到的图像延时大概有3秒左右，是缓冲区的原因吗？

调用libRtspClientLib.so文件出现Segmentation fault

c++的test例子直接调用.h文件没有问题，但是如果是调用.so文件会出现段错误

LightTrack的issue关了只能在这提问

您好，向您请教关于NanoTrack在RK3588平台的C++实现出现的问题。我参考NanoTrack原作者的C++代码和您使用lighttrack的代码写了使用rknn模型的代码，但是在解析输出的结果时出现问题：预测的目标框位置差距很大而且从第二帧开始预测框就不对了，想询问解决的办法！
NanoTrack跟LightTrack很相似，我的模型也是按照你的差不多结构设置的。

是否可以增加推送rtsp流的编码接口

是否可以增加基于gstreamer rtspserver 插件，实现不同输入的推流服务

无法连接

请问我这个怎么无法连接，直接用playbin是可以的
