我目前正在使用这个命令：
libcamera-vid -t 0 --inline --framerate 30 -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream1}' :demux=h264
尽管传感器的分辨率为 2592 x 1944，但驱动程序似乎仅将其设置为 640 x 480 的分辨率（输出：）
libcamera-vid -t 0 --inline --framerate 30 -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream1}' :demux=h264

视频源看起来一尘不染。另一方面……当我使用命令
libcamera-vid -t 0 --inline --framerate 30 -o - --width 1920 --height 1080 | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream1}' :demux=h264
我只能看到原始视角的一小部分。我该如何告诉相机使用 1080p30？
答案1
两个月后你也许还会有答案，但这个问题经常会发生。
根据设置的分辨率（以及比例）裁剪相机图片。
尝试 1280x960 您将能看到大部分角度。
其中一个硬件站点上有一张包含视频模式信息的图片。根据分辨率显示带有方框的图片。
