Comment (by pero):

 Thank you!

 Yes it is working without audio.
 I'm a bit stucked here, because i need the audio. The original sources are
 two IP cams:

 {{{
 ffmpeg
 -rtsp_transport tcp -thread_queue_size 512 -i rtsp://X.X.X.X:555
 -rtsp_transport tcp -thread_queue_size 512 -i rtsp://X.X.X.X:556
 -filter_complex
 "[0:v]scale=736:552,crop=w=222:h=552:x=288:y=0[outside];[1:v][outside]overlay=shortest=1:x=5:y=5[pip]"
 -map [pip] -map 1:a -c:a aac -ab 64k -c:v h264_nvenc -cbr 1 -b:v 1800k
 -maxrate 2000k -r 25 -g 100 -bf 2 -refs 4 -no-scenecut 1 -strict_gop 1
 -profile:v high -pixel_format yuv420p -preset default
 -f hls -hls_time 4 -hls_list_size 5400 -hls_flags
 +delete_segments+append_list+omit_endlist test.m3u8
 }}}

 I tried to play with setpts, without success

 The weird thing is that one of the cams returns this:
 {{{Duration: N/A, start: 0.000000, bitrate: N/A}}}

 but the other:
 {{{Duration: N/A, start: 0.241000, bitrate: N/A}}}

 Is it normal?
 Can you please suggest something, what I should try to make this work with
 audio?

 THX!
