Graphics, sound and multimedia • Re: TC358743 HDMI to CSI-2 install instructions

Hey guys i managed to install it and run it almost ok.

My biggest problem is that I'm basically proxying my signal from HDMI to analog output meaning 576i (720x576)

I have set this resolution on my mac and sending it to the HDMI right, but this is what I get after doing all the shenanigans to set the timings and etc following the tutorial here:

Code:

gst-launch-1.0 v4l2src ! "video/x-raw,framerate=50/1,format=UYVY" ! v4l2convert ! kmssink sync=false alsasrc ! audio/x-raw,rate=48000,channels=2 ! pulsesinkSetting pipeline to PAUSED ...Pipeline is live and does not need PREROLL ...Pipeline is PREROLLED ...Setting pipeline to PLAYING ...New clock: GstAudioSrcClockERROR: from element /GstPipeline:pipeline0/v4l2convert:v4l2convert0: failed to activate bufferpoolAdditional debug info:../sys/v4l2/gstv4l2transform.c(334): gst_v4l2_transform_decide_allocation (): /GstPipeline:pipeline0/v4l2convert:v4l2convert0:failed to activate bufferpoolExecution ended after 0:00:00.005208413Setting pipeline to NULL ...Freeing pipeline ...

it "kinda" works with videoconvert instead of v4l2convert
running this command:

Code:

gst-launch-1.0 v4l2src ! "video/x-raw,framerate=50/1,format=UYVY" ! videoconvert ! fbdevsink sync=false alsasrc ! audio/x-raw,rate=48000,channels=2 ! pulsesink

but the image is not stable it flickers on top and bottom, super annoying, video here: https://photos.app.goo.gl/B4zzkAJBi5wisuKB6

I had tried to find an EDID that supports 736x576, I saw some old posts about it with the TC358743 where @6by9 talks about it but no good
any help is welcome, and thanks a lot
