Hi,everyone,

     I use the ffmepg(version: 3.2.2 static) command line to transcode
 live udp stream(mpgv & mpga codec) and then send the coded data to
nginx-rtmp server,but problem occurred after server hours,fatal error is

WriteN, RTMP send error 10054 <129 bytes>

WriteN, RTMP send error 10053 <41 bytes>

 WriteN, RTMP send error 10038 <42 bytes>

av_interleaved_write_frame(): Operation not permitted

    Last message repeated 1 times

[flv @ 00000000039cbb40] Failed to update header with correct duration.

Error writing trailer of rtmp://10.10.10.188/hls/live5: Operation not
> permitted




ffmpeg transcoding command line is

ffmpeg -f mpegts -v error -i "udp://@225.0.0.5:9000?overrun
> _nonfatal=1&buffer_size=10000000
> <http://225.0.0.5:9000/?overrun_nonfatal=1&buffer_size=10000000>" -vcodec

> 720x576 -vf w3fdif -y -f flv rtmp://10.10.10.188/hls/live5

using nginx(version: nginx-1.11.3 and also tried verion 1.6.3) and
nginx-rtmp-module(https://github.com/arut/nginx-rtmp-module,git latest
version) as rtmp server ,and source udp stream seems to be ok,vlc plays
well.

Any help is appreciated.
