[FFmpeg-user] bad performance when streaming udp from png image2pipe source

finally I have some progress by forcing the input frame rate to 1 and the
output frame rate to 20, this produces a much better frame rate in the
target machine. but still I have many problems ( occasional images smearing,
and lagging) in my destination ( udp receiver ).
I am getting many errors in ffplay, maybe you can help me understand what is
wrong with the stream.
ffmpeg command and output:
ffmpeg -an -y -r 1 -f image2pipe -vcodec png -i /sdcard/tempfifo -r 20
-bsf:v h264_mp4toannexb -b 300400 -f mpegts udp://192.168.1.23:1235
