[FFmpeg-user] Error Capturing MJPEG Stream from Linux version

[Alejandro Escudero]

Hi,



Please your help,  I am on Linux (Centos 7) trying to capture a MJPEG stream from an IP Camera and save it as MP4, but I am getting this error:


[ingenient @ 0x2637be0] Could not find codec parameters for stream 0 (Video: mjpeg, none(bt470bg/unknown/unknown)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options


Note: On windows 10 FFmpeg version I don´t have this problem (ffmpeg version N-94423-ga0c1970781 Copyright (c) 2000-2019 the FFmpeg developers  built with gcc 9.1.1 (GCC) 20190716)




Command (Linux):


ffmpeg -t 58 -i "http://user:pass@cameraip:8080/video.cgi"<%22http:/user:pass at cameraip:8080/video.cgi%22> -f segment -segment_time 16 -strftime 1 '/var/www/myrecordings/%Y-%m-%d_%H:%M:%S.mp4'
