Hi All,
I add a Stream in my ffserver config as below:
<Stream test.mjpg>
Feed feed1.ffm
Format mjpeg

VideoFrameRate 30
VideoSize 1280x720
VideoBitRate 256
VideoBufferSize 400
#VideoGopSize 3
VideoIntraOnly
#NoAudio
#Strict -1
</Stream>

The out of memory was happened. Does someone have idea?
the log that I capture below:
