器件型号：SK-AM62P-LP
主题中讨论的其他器件：AM62P

工具与软件：

您好！

我们已经实施了4摄像头解码器驱动程序,但当我们运行我们的管道,我们得到100%在每个核心,如下图所示

我们当前的管道如下所示

GST_DEBUG=3 gst-launch-1.0 -v \
v4l2src device=/dev/video2 ! queue max-size-buffers=8 max-size-bytes=0 max-size-time=0 ! \
video/x-raw,format=UYVY,width=1280,height=720,framerate=10/1 ! \

sink_3::xpos=640 sink_3::ypos=360 ! \
queue ! video/x-raw,width=1280,height=720,framerate=120/1 ! queue ! kmssink

我们有什么可以改进的地方吗？

您好、Sergio、

首先、您是否获得了正确的摄像头数据？

如果是这种情况,我认为" videoscale"插件可能是最消耗 CPU 的东西。请优化您的流水线。

另外、请尝试如下所示的操作：

gst-launch-1.0 \
v4l2src device=/dev/video-ov5640-cam0 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720, format=YUY2 ! ticolorconvert ! queue ! mosaic.sink_0 \
v4l2src device=/dev/video-ov5640-cam1 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720, format=YUY2 ! ticolorconvert ! queue ! mosaic.sink_1 \
v4l2src device=/dev/video-ov5640-cam2 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720, format=YUY2 ! ticolorconvert ! queue ! mosaic.sink_2 \
v4l2src device=/dev/video-ov5640-cam3 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720, format=YUY2 ! ticolorconvert ! queue ! mosaic.sink_3 \
timosaic name=mosaic \
sink_0::startx=300 sink_0::starty=0 sink_0::width=640 sink_0::height=480 \
sink_1::startx=980 sink_1::starty=0 sink_1::width=640 sink_1::height=480  \
sink_2::startx=300 sink_2::starty=500 sink_2::width=640 sink_2::height=480 \
sink_3::startx=980 sink_3::starty=500 sink_3::width=640 sink_3::height=480 ! \
video/x-raw, width=1920, height=1080, format=NV12 ! queue ! kmssink driver-name=tidss sync=false force-modesetting=true

是的、但我们在图像上感应到有点延迟

正如您提到的、我们在流水线上进行了一些更改

gst-launch-1.0 \
v4l2src device=/dev/video2 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720,framerate=30/1, format=UYVY ! ticolorconvert ! queue ! mosaic.sink_0 \
v4l2src device=/dev/video3 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720,framerate=30/1, format=UYVY ! ticolorconvert ! queue ! mosaic.sink_1 \
v4l2src device=/dev/video4 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720,framerate=30/1 ,format=UYVY ! ticolorconvert ! queue ! mosaic.sink_2 \
v4l2src device=/dev/video5 ! queue max-size-buffers=1 leaky=2 ! video/x-raw, width=1280,height=720,framerate=30/1 ,format=UYVY ! ticolorconvert ! queue ! mosaic.sink_3 \
timosaic name=mosaic \
sink_0::startx=0 sink_0::starty=0 sink_0::width=640 sink_0::height=360 \
sink_1::startx=640 sink_1::starty=0 sink_1::width=640 sink_1::height=360  \
sink_2::startx=0 sink_2::starty=360 sink_2::width=640 sink_2::height=360 \
sink_3::startx=640 sink_3::starty=360 sink_3::width=640 sink_3::height=360 ! \
video/x-raw, width=1280, height=720, framerate=60/1, format=NV12 ! queue ! kmssink driver-name=tidss sync=false force-modesetting=true

但每个内核仍具有100%的效率

我正在运行更多测试、得到了这些结果

如果我只在"dev/video2"上使用此管道运行相机" gst-launch-1.0 -v v4l2src device=/dev/video3 ! video/x-raw、width=1280、height=720、format=UYVY！ kmsink "我的输出已低于

此故障未出现在单"dev/video3"和单"dev/video4"上。

但当我运行它在马赛克模式这个错误不会出现

您好、Sergio、

dev/video2是否对应于30102000.ticsi2rx 上下文0？如果是这种情况、这是连接了多个摄像头时上下文0的已知问题。

当您使用我之前共享的脚本设置路由时、请尝试跳过上下文0。

此致、

有没有我们遗漏的东西？

而关于问题与100%的 CPU 使用马赛克,我们发现我们的问题是由于视频扩展,有没有办法使用硬件加速与管道?
