But am facing memory consumption issue within 2 hours all RAM memories are
full and streams are jerking to play.
What is the solution for this problem. Is hardware is enough to play 20
streamers.
Am using below commands for streaming services
=================================================================
# Stream 1
STREAM_NAME=stream1
STREAM_PID_PATH=/tmp/$STREAM_NAME-pid
INPUT_URL=udp://224.1.1.1:1100
CH_NAME=mv_movies_hd
ffmpeg -i "$INPUT_URL?overrun_nonfatal=1&fifo_size=5000000" \
-filter_complex
"[v:0]split=2[vtemp001][vtemp002];[vtemp001]scale=w=640:h=360[vout001],[vtemp002]scale=w=854:h=480[vout002]"
\
-map [vout001] -c:v:0 mpeg2video -b:v:0 600k -maxrate:v:0 900k
-bufsize:v:0 1200k \
-map [vout002] -c:v:1 mpeg2video -b:v:1 1000k -maxrate:v:1 1500k

-hls_wrap 40 -hls_allow_cache 0 \
-hls_delete_threshold 1 \
-hls_flags delete_segments \
-hls_start_number_source datetime \
-start_number 10 \
-hls_playlist_type event -master_pl_name $CH_NAME.mpeg \

Look at the previous responses to the same query earlier on.
16 GB isn't even enough for the workload you're hitting.
I'm a newbie, but what you write doesn't seem right to me, Dennis. If
karthik is running for 2 hours before the problem shows up, it seems
likely to me that there may be a stale-buffer issue.
...just my 2 cents.
