https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1487764/am62a7-gstreamer---low-framerate

器件型号：AM62A7

工具/软件：

您好！

我将使用 AM62A7 EVM、一个 adrucam v3link d-ch 适配器板插入 FPD3 ISX031摄像头模块。 (这是一款 YUV ~3MP 摄像头模块、不需要 ISP)

我在~30fps 时摄像头流式传输没有问题、但我运行的 gstreamer 流水线只能处理~7ish 帧/秒：

`gst-launch-1.0 -v v4l2src device=/dev/video4 ! 排队！视频/x-RAW、宽度=1920、高度=1536、格式=UYVY、帧速率=30/1！视频转换标度！ video/x-raw、宽度=1920、高度=1536、格式=NV12、帧速率=30/1！排队！ tiovxmultiscaler！排队！ video/x-raw、format=NV12、width=1920、height=1080！排队！ fpsdisplaysink fps-update-interval=5000 name=rgb text-overlay=false sync=false video-sink="kmssink driver-name=tidss force-modesetting=true sync=false"`

当我`设置` v4l2src IO-mode=5 时、gstreamer 流水线甚至无法启动、说没有存储器：

如何让系统以30 FPS 显示输出？

您好、Stuart、

您的管道很可能会因视频转换扩展插件而减慢。您是否可以尝试改用"ticolorconvert"？

此致、

我尝试使用 TIcolorconvert。 GstFPSDisplaySink 报告增加了大约+2 FPS (从6-7增加到9ish)、而帧速率在视觉上仍然相当低。此外、大约有0.5秒的延迟。我假设这是因为队列数。

还有其他建议吗？理想情况下、我希望以相对较低的延迟实现接近30fps 的帧速率。

您好、Stuart、

如果删除颜色转换和多标量、则管道仍应正常工作。您能尝试一下吗？

您好、Stuart、

如果您使用的是最新发布的 SDK 10.1代码：

您是否可以尝试将 video-sink="kmssink driver-name=tidss sync=false force-modesetting=true"修改为"kmssink driver-name=tidss sync=false skip-vync=true plane_id=31"、看看是否有用？

此致、

有问题的显示器只是一个1080p 显示器-所以我认为它拒绝显示任何不是正确分辨率的东西。如果我使用4K 显示器、它会起作用吗？

您好、Stuart、

可能尝试使用其他显示器。我能够将1936x1100流式传输到1920x1080显示器而不会缩小：

gst-launch-1.0 \

很抱歉耽误响应。我在使用此系统时仍然遇到问题。大多数 gstreamer 流水线似乎无法正常工作- I 必去之地 转换颜色、然后重新缩放视频。

我还注意到您使用的`是 T Ü V GST-launch-1.0 v4l2src device=/dev/video-imx390-cam0 io-mode=dmabuf-import` ,我无法使用,因为它似乎破坏了我创建的任何管道。我是否缺少设备上的软件、或者是因为我未接收原始帧、而是接收 UYVY 帧？

您好、Stuart、

我在您的日志中看到以下错误：

您能共享"media-ctl -p"的输出吗？

在多次尝试重现错误后、我最终使用前面提到的命令让系统正常工作。它不清楚为什么,我不确定它将在明天再次工作-但它可能需要与相机的细节(它往往在打开时流,而不是等待命令).

当流式传输没有颜色转换或 msc 节点-我得到一个合理的帧速率/延迟-这是很好的。我们是否可以通过重新分配节点使系统以更高的帧速率运行-或者这是不可能的？

无论哪种方式-感谢您的帮助

Stuart、

瓶颈是视频转换扩展插件。其中一种解决方案是使 TI 的多分频器支持 UYVY、这样就不必将 UYVY 转换为 NV12。

我将在未来的版本中请求支持此功能。

此致、
