Once the configuration is done, and assuming you dont want to change any parameter, you dont need a LCD screen nor Putty, is there a way to switch to transmit via a gpio pin ?

Hi Jim there is an issue with MT (well LAVfilters) that miss reports 16:9 if your using H265 ? With H264 it should be ok I TX in 16:9 in H264 and It works ok.

All best John

Jim

Please give me further details of what settings don't work for you - are you getting any picture? A photo of Menu 1 in the non-working configuration is probably best.

I have found a bug in the Jetson code with the 16:9 setting, but not sure that you are running the Jetson.

Hi Dave,

I think I maybe having the same problem as Jim. I’m trying to set the format when using S2 QPSK, H.264 to 16:9, but the software won’t let me. If I go into format, you can select 16:9, but when you go back it’s still set to 4:3. When using M-PEG2 it seems to work fine.
