[FFmpeg-user] *** drop! and *** dup!

[Haris Zukanovic]

Hi,

I am using ffmpeg to output streams in HLS with ssegmenter.
I am seeing quite lot these messsages in the log but without any visible 
consequences in the output stream.
The output stream seems to be relatively ok even though I sometimes see 
these messages repeated many many times.

Is that something to worry about? and how do I attempt to fix it?

My command
/root/bin/ffmpeg -y -hide_banner -loglevel verbose -nostats -threads 
auto -timeout 5000000 -analyzeduration 10000000 -probesize 10000000 
-fflags +genpts -i 
'udp://235.5.1.111:5000?reuse=1&timeout=10000000&fifo_size=1000000&overrun_nonfatal=0&buffer_size=16777216' 
-c:v h264 -b:v 1500k -maxrate:v 3000k -bufsize:v 15000k -refs 6 -bf 5 -g

-segment_list /origin/tmp/ST041/tv/chunklist.m3u8 -segment_time 10 
-segment_list_size 3 -segment_list_flags -cache+live -strftime 1

-update 1 -q:v 0 /origin/tmp/ST041-screenshot.jpg


thank you in advance for any pointers...
