I’m using the tegra build R32.2.1
what I would like to do is provide a nice video image to the output screen. Now I don’t have a problem with that, I simply use gstreamer and the nvoverlaysink which works like a charm. However I still see in the background behind the video output coming from diverse sources that are writing stuff to the standard out. So how do I get rid of this?
My idea was to deny the kernal a video source for its standard out and this would in turn make sure no other program would write to the video anymore.
So first of all, is this a correct assumption and second how do I do this?
When I look at my dmesg I can see the following kernel command:
Kernel command line: root=/dev/mmcblk0p1 rw rootwait console=ttyS0,115200n8 console=tty0 OS=l4t fbcon=map:0 net.ifnames=0 video=tegrafb no_console_suspend=1 earlycon=uart8250,mmio32,0x3100000 nvdumper_reserved=0x2772e0000 gpt usbcore.old_scheme_first=1 tegraid=22.214.171.124.0 maxcpus=6 boot.slot_suffix= boot.ratchetvalues=0.983055.1 bl_prof_dataptr=0x10000@0x275840000 sdhci_tegra.en_boot_part_access=1 root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4
So I imagine I need to change this line? specifically the part where it says video=tegrafb? However I don’t find this line anywhere so it is probably something that is generated during flashing. So this is where I’m stuck, can anyone help me here please?
