[FFmpeg-user] Errors while muxing into .mkv from ip camera

[Ddfsdf sdfsdf]

Hello!
I'm trying to convert video stream received from IP camera into 
.mkv container. While processing file ffmpeg prints errors 
described in log file.
What's the reason of arising these errors in log? 
What can I do to eliminate them?
