[FFmpeg-user] ffmpeg can not post new video data to ffserver

[Soho Soho123]

Hi All,

I got the problem about ffmpeg post fail to ffserver.
I use the solution ffmpeg+ ffserver for a stream server.
the stream can work for a few minutes, then ffmpeg can not post video data
via http://localhost:8090/feed1.ffm
the command line I use for ffmpeg:
ffmpeg -loglevel debug -f video4linux2 -r 30 -s 1280x720 -input_format h264
-i /dev/video1 -vcodec
copy http://localhost:8090/feed1.ffm


ffserver can not receive new video data from ffmpeg if the stream is
running for about 30~60 minutes.
I check the errno from ffmpeg av_interleaved_write_frame()
it says "No such file or directory"
errno is 2

Does anyone have ideas?
