I have a custom carrier board which is developed for Jetson TX-1. My requirement is two different VGA output on two monitors.
I have a free PCIe interfaces on our custom carrier board. We have connected a PCIe to VGA converter to connect other monitor. I am using VL-MPEe-V5 from Versalogic which is based on Silicon Motion SM750 chipset.
Jetpack version for my Jetson TX-1: # R32 (release), REVISION: 3.1, GCID: 18186506, BOARD: t210ref, EABI: aarch64, DATE: Tue Dec 10 06:58:34 UTC 2019
I am using sm750fb driver from kernel source /kernel-4.9/drivers/staging/sm750fb/ . I am using this driver as a module. The driver is create a node in the /dev/fb1 .
We have a use case where we are not using the in-built Tegra display controllers. Instead, we are using an external VGA display card over PCIe bus. This PCI to VGA card’s driver is creating one framebuffer node i.e fb1.
Our video input source is connected to MIPI CSI bus as /dev/video0
We would like to display the above video input to the monitor connected to the PCIe to VGA card using gstreamer. The video source give’s us raw videos; we want to display this video directly to the monitor.
Please help us to display the input video to the monitor.
Hi,
This kind of display is not supported in default release. We don’t have much experience about it. Would see if some other users have the experience and can suggest next.
By default we support rendering frames to HDMI devices through X11 and DRM.
Hi,
We don’t have much experience about using fbdevsink. This would need other users to share experience.
Beside using gstreamer, are you able to allocate a CPU buffer and send it over PCIe to the VGA card? Not sure if the device supports some APIs which can do this. Like the psuedo code:
