I apologize I forgot to include the command we use:
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 &
Thank you,
Osama
