ffmpeg实时流错误: av_interleaved_write_frame()：断管

Question

我正在尝试使用ffmpeg流视频直播，输入来自UDP源。大多数情况下，它可以正常工作，但我可以看到以下日志行和ffmpeg stop的转换/提要推送到rtmp服务器。下面的几行日志可供参考。此问题是否与到达目的地或源时的网络有关，还是与我需要在ffmpeg命令中更改的内容有关？

在下面添加ffmpeg命令：

ffmpeg -err_detect aggressive -fflags discardcorrupt -i udp://230.1.1.2:11000?fifo_size=5000000&overrun_nonfatal=1 -analyzeduration 25M -probesize 50M -threads 0 -vsync 1 -filter_complex [i:0x202]yadif,setdar=16/9[1out1];[i:0x202]yadif,setdar=16/9[1out2];[i:0x202]yadif,setdar=16/9[1out3];[i:0x202]yadif,setdar=16/9[1out4] -map [1out1] -map i:0x29e -c:v libx264 -x264-params nal-hrd=cbr -b:v 200k -maxrate 200k -bufsize 300k -r 15 -g 30 -profile:v baseline -level 3.0 -pix_fmt yuv420p -c:a libfdk_aac -b:a 32k -ac 2 -ar 48000 -sc_threshold 0 -s 256x144 -tune film -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -x264opts opencl -f flv rtmp://ipaddress:1935/rtmp/push/test1-map [1out2] -map i:0x29e -c:v libx264 -x264-params nal-hrd=cbr -b:v 500k -maxrate 500k -bufsize 750k -r 25 -g 50 -profile:v baseline -level 3.0 -pix_fmt yuv420p -c:a libfdk_aac -b:a 64k -ac 2 -ar 48000 -sc_threshold 0 -s 512x288 -tune film -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -x264opts opencl -f flv rtmp://ipaddress:1935/rtmp/push/test2 -map [1out3] -map i:0x29e -c:v libx264 -x264-params nal-hrd=cbr -b:v 1000k -maxrate 1000k -bufsize 1500k -r 25 -g 50 -profile:v main -level 3.0 -pix_fmt yuv420p -c:a libfdk_aac -b:a 64k -ac 2 -ar 48000 -sc_threshold 0 -s 1024x576 -tune film -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -x264opts opencl -f flv rtmp://ipaddress:1935/rtmp/push/test3 -map [1out4] -map i:0x29e -c:v libx264 -x264-params nal-hrd=cbr -b:v 1800k -maxrate 1800k -bufsize 2700k -r 25 -g 50 -profile:v main -level 3.1 -pix_fmt yuv420p -c:a libfdk_aac -b:a 64k -ac 2 -ar 48000 -sc_threshold 0 -s 1280x720 -tune film -af aresample=async=1:min_hard_comp=0.100000:first_pts=0 -x264opts opencl -f flv rtmp://ipaddress:1935/rtmp/push/test4

Answer 1

添加

-f flv -flvflags no_duration_filesize

将删除错误，因为活动流无法更新标头。
