I'm using ffmpeg to push raspberrypi video feeds (CSI camera) to a nginx-RTMP server then the nginx push it to youtube. My problem is, every time when I run the ffmpeg command, it always gives me input/out error. Then it is working fine when I run the exact same ffmpeg command for the 2nd time. How do I resolve this problem? I want to start the ffmpeg command in a script file and put the script in crontab so that it can start the live streaming automatically. But this error makes it impossible to do that.
my ffmpeg command is as below(change the real domain name to mydomain.com):
ffmpeg -thread_queue_size 512 -f v4l2 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -input_format yuyv422 -video_size 1280x720 -framerate 30 -i /dev/video0 -vf eq=gamma=1.5:saturation=1.3 -c:v h264_omx -b:v 20480K -vsync 1 -g 16 -f flv rtmp://mydomain.com:1935/live/
the error log:
