[FFmpeg-user] FFMPEG fails 5% responding to SIGTERM and SIGINT

[Osama Alshaykh]

Hi,

The console output are normal.  We could not stop the process using SIGTERM or SIGINT.  The parameters we call are:

DISPLAY=$1
OUTPUT=$2
: ${RESOLUTION:=640x480}
: ${RATE:=30}
: ${PRESET:=veryfast}
: ${QUEUE_SIZE:=4096}
sleep 10
exec ffmpeg -y \
-f x11grab -r $RATE -s $RESOLUTION -thread_queue_size $QUEUE_SIZE -i :$DISPLAY.0+0,0 \
-f alsa -thread_queue_size $QUEUE_SIZE -i plug:asnoop$DISPLAY -acodec libfdk_aac -ar 44100 \
-c:v libx264 -preset $PRESET -pix_fmt yuv420p -r $RATE \
-crf 28 -g 120 -keyint_min 5 -tune zerolatency -threads 1 \
-f mp4 $OUTPUT > /tmp/jibri-ffmpeg-$DISPLAY.out 2>&1 &

We did not try different parameters to duplicate the issue.

Thank you,
Osama
