Hi, I use something similar with two RTSP signals and it works for me. This is the command I execute:
ffmpeg -rtsp_transport tcp -thread_queue_size 512 -rtbufsize 50M -r 15 -i rtsp://XXXX -rtsp_transport tcp -thread_queue_size 512 -rtbufsize 50M -r 15 -c:a aac -i rtsp://YYYY -filter_complex "[0:v]pad=iw*2:ih,setpts=PTS-S TARTPTS[bg]; [1:v]setpts=PTS-STARTPTS[fg]; [bg][fg]overlay=w[out]" -map "[out]" -f hls -hls_time 2 -hls_list_size 5 -use_localtime 1 -use_localtime_mkdir 1 -hls_segment_filename 'LIVE/file-%s.ts' -map a -ar 16000 -ac 1 -ab 64000 -c:a aac -y output.m3u8 I think perhaps you need some higher buffer_size parameter or add a thread_queue_size parameter (like I do). If I can think of any more parameters you may need, I say to you ;) Luck! 2018-04-26 14:41 GMT+02:00 Hristo Ivanov Ivanov <[email protected]>: > Hi, > > I am trying to overlay several network inputs(udp streams).
