在Gstreamer管道中使用DeepStream插件

我尝试在Gstreamer管道上使用DeepStream插件，包括编解码器、视频分析块和TensorRT。但有一个奇怪的错误

我已经尝试了gst-launch-1.0和videotestsrc以及ximagesink在屏幕上显示

代码：

gst-launch-1.0 videotestsrc！视频转换！x264enc tune=零延迟！h264parse！avdec_h264！视频转换！ximagesink gst-launch-1.0 videotestsrc！视频转换！x264enc tune=零延迟！h264parse！nvdec_h264！nvvidconv！ximagesink 错误：

nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400
nvcuvidh264dec0: Decode error result = 400

如果这样做，则生成的H.264流将采用4:4:4颜色采样。只有少数解码器将处理此配置文件

您必须强制编码器改用4:2:0

gst-launch-1.0 videotestsrc ! video/x-raw, format=I420 ! x264enc ...
