Try changing -f h264 to -f flv. YouTube Stream Now prefers flv for some reason. Here’s what I use from a Wyze Cam v3 with RTSP firmware:

./ffmpeg -thread_queue_size 2048 -i 'rtsp://anonymous:password@192.168.1.49/live' -vcodec copy -acodec copy -t 2:00:00 -f flv "rtmp://a.rtmp.youtube.com/live2/my-youtube-streaming-key"

and it works just fine:

https://www.youtube.com/channel/UCIVY11504PcY2sy2qpRhiMg/live <https://www.youtube.com/channel/UCIVY11504PcY2sy2qpRhiMg/live>

and from a Reolink RLC-423:

./ffmpeg -re -thread_queue_size 512 -rtsp_transport tcp -i "rtsp://anonymous:password@192.168.1.11:554" -f concat -safe 0 -i playlist.txt -vcodec copy -acodec copy -t 01:47:02 -f flv "rtmp://a.rtmp.youtube.com/live2/my-other-youtube-key”

The playlist is because the Reolink doesn’t have an audio track, which YouTube Stream Now requires.
