I have a python program that launches an ffmpeg process where the process has two inputs 1. stdin (rawvideo) and 2. udp port (klv). klv_sender.py try: while True: sock.sendto(packet, (localhost, 4444)) except BrokenPipeError: pass ffmpeg command: ffmpeg -loglevel verbose -f rawvideo -vcodec rawvideo -pix_fmt bgr24 -s 704x480 -r 30 -i - -f data -i udp://0.0.0.0:4444 -map 0:v -c:v libx264 -preset ultrafast -tune zerolatency -map 1:d -c:d copy -f mpegts localhost:1234?pkt_size=1316 I see data coming from klv on port 4444 and video data is being sent but, for some reason, I only get klv data. It seems like something blocks so that only klv data is getting sent. If I remove klv from the command video is fine Any thoughts as to why one process seems to be blocking? I have sent the sleep time to 1/30 for both streams. The loglevel outputs messages indicating video/klv are received but only 2 packets of video and like 1200 klv packets. Thanks!
