Hello everybody,
ffmpeg -re -f lavfi -i testsrc=rate=30 -re -thread_queue_size 131072
-f data -i udp://127.0.0.1:4444 -map 0:0 -map 1:0 -c:v h264 -c:d
copy -f mpegts test.ts
This is the output of the command above. I simply want to record the
data coming from udp synced with video. I push some KLV encoded metadata
from udp://127.0.0.1:4444 but recording stops at frame 51.

No pixel format specified, yuv444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
