Привет всем!
Есть несколько камер, на них поднято вещание в RTSP
Изначально использовались Win сервера и Macroscope, но решение не гибкое, дорогое и не стабильное оказалось.
Поэтому решили перейти на Linux, используется Debian
Запись пытался делать с помощью ffmpeg командой:
/usr/bin/ffmpeg -i rtsp://172.16.30.11:554/user=admin_password=123456_channel=1_stream=0.sdp?real_stream -y -r 20 -s hd720 -b 4000k -vcodec libx264 -threads 8 -f segment -strftime 1 -segment_time 30 -segment_format mp4 /opt/video/cam1/%Y-%m-%d-%H-%M-%S.mp4
Но видео записываются кривые, кадры накладываются, плывут и рябь появляется.
Не могу понять в чем дело, на Macroscope качество было отличное.
