Streams stop when creating a quad split Multi-viewer using FFMPEG

admin

Created a FFMPEG script that takes in 4 SRT Live Streams and displays them in a quad split MV. However when I launch this script all 4 SRT streams will play but 3 will pause and 1 will play.

ffmpeg \
-re -hwaccel auto -hwaccel_output_csp videocore \
-stream_loop -1 \
-i "srt://address:5000?streamid=stream-id" \
-stream_loop -1 \
-i "srt://address:5000?streamid=stream-id" \
-stream_loop -1 \
-i "srt://address:5000?streamid=stream-id" \
-stream_loop -1 \

"srt://address:5000?streamid=stream-id"

getting a lot of the below error;

16:48:49.628704/SRT:RcvQ:w2!W:SRT.qr: @214003038:No room to store incoming packet seqno 649744568, insert offset 7190. Space avail 0/8192 pkts. (TSBPD ready in -12342ms, timespan 6093 ms). GETTIME_MONOTONIC drift 0 ms.

I’ve tried smaller resolution and adjusting buffer sizes as well as the other flags but I’m not sure what else I can do.
