 Summary of the bug:

 Stream does not start when using stream_loop -1 together with
 filter_complex overlay. With stream_loop 0 stream is ok, but of course
 doesn't update the overlay.

 How to reproduce:
     'ffmpeg',
     '-thread_queue_size', '1024',
     '-i', 'rtsp://...',
     '-f', 'image2',
     '-stream_loop', '-1',
     '-i', 'picture.png',
     '-filter_complex', 'overlay=(main_w-
 overlay_w)/2:main_h*0.1-overlay_h',
     '-acodec','aac',
     '-ar', '44100',
     '-ab', '128k',
     '-f', 'flv',
     '-g', '30',
     '-vcodec', 'libx264',
     '-preset', 'ultrafast',
     '-crf', '30',
     'rtmp://...'

 In single line:

 ffmpeg -thread_queue_size 1024 -i rtsp://... -f image2 -stream_loop -1 -i
 picture.png -filter_complex "overlay=(main_w-
 overlay_w)/2:main_h*0.1-overlay_h" -acodec aac -ar 44100 -ab 128k -f flv
 -g 30 -vcodec libx264 -preset ultrafast -crf 30 rtmp://...

 ffmpeg version 4.4 is the problem. Works fine on FFmpeg 4.3.2. Also tried
 loop instead of stream_loop. Same result.
