Hi there, I have a wierd problem
after fidling with tmm and finaly made it to build on windows (you can see the repo here)
https://github.com/veso266/tmm
https://github.com/veso266/tmm-mpeg2ts
I can see stream fine with ffprobe: ffprobe -hide_banner -loglevel debug -i udp://@232.4.202.21:5003
I can even play it fine (audio and video) using ffplay: ffplay -i udp://@232.4.202.21:5003
I use VLC Media Player version 3.0.6
but (I believe) because MTU is too large (it should be no larger then 1500), but its 7520, so VLC Media player cannot play the stream
and also one of thecanalyzers I use: https://github.com/Cinegy/TsAnalyser
Also complains, cuz MTU is to large
So how can I decrease the packet size so it will fit in ethernet frame and not be a Jumbo Frame?
This ffmpeg command plays fine in vlc: ffmpeg -re -f lavfi -i smptebars=size=1280x720:rate=30 -f lavfi -i sine=frequency=1000:sample_rate=48000 -c:v libx264 -tune zerolatency -preset veryfast -g 60 -b:v 2M -c:a aac -b:a 128k -f mpegts "udp://232.4.202.21:5003?pkt_size=1316"
this one doesn't: ffmpeg -re -f lavfi -i smptebars=size=1280x720:rate=30 -f lavfi -i sine=frequency=1000:sample_rate=48000 -c:v libx264 -tune zerolatency -preset veryfast -g 60 -b:v 2M -c:a aac -b:a 128k -f mpegts "udp://232.4.202.21:5003" (so u can see what I mean by decreasing packet size
I wanted to eventualy generate AAC (1khz sine wave) audio and colorbars and maybe add teletext stream and HbbTV stream with tmm
Thanks for Anwsering and Best Regards
