Delay in display

[skowron0]

Hi,

I use omxplayer to display the image of five Chinese 2Mpx cameras. Over time, the delayed image increases. After 30 minutes it can be up to 8 minutes. An interesting problem occurs when the camera is in night mode and the larger part of the screen is black. When in day or night mode with a large amount of gray this problem does not occur. This would suggest a camera problem but when I display the image using vlc this problem does not occur. The problem occurs on all cameras whether I display an image from one or all five. Does anyone have any ideas?

Additional information:

• Stream settings 640x480px 15fps.
• The platform is raspbery pi 3
• command line when I use: 1) omxplayer --live --timeout 60 --aidx -1 -o hdmi --video_fifo 1 --video_queue 1 rtsp://192.168.7.55:1051/user=xxx_password=xxx_channel=1_stream=1.sdp?real_stream --win 0 0 640 540 2) omxplayer --live --timeout 60 --aidx -1 -o hdmi rtsp://192.168.7.55:1051/user=xxx_password=xxx_channel=1_stream=1.sdp?real_stream --win 0 0 640 540 3) omxplayer --live --timeout 60 --aidx -1 -o hdmi --avdict rtsp_transport:tcp rtsp://192.168.7.55:1051/user=xxx_password=xxx_channel=1_stream=1.sdp?real_stream --win 0 0 640 540
