In my case, I modify ffmpeg source code,wrap it as a service for transcode rtsp to hls;But log shows error:
ffmpeg: Application provided invalid, non monotonically increasing dts to muxer in stream 1: 93840 >= 93690
OnTaskStateChange, TaskId: 13, NewState: STATE_ERROR, ERROR: -8980(FE_interleaved_write_frame)

While i use the original ffmpeg command line,to do up thing.it was successful for trancoding rtsp to hls;
FFMPEG CLI :
$ /opt/pix/ffmpeg/ffmpeg -i rtsp://192.168.2.22:10554/23 -strict -2 -c:v libx264 -c:a aac -f hls index.m3u8

I really don't knwon why,Could anyone help me?
