[FFmpeg-user] system freeze when running ffserver and ffmpeg, it is not stable

[Soho Soho123]

Hi all,

When I try to MJPG Streamer to send video frame from usb webcam to
remote client,
it is stable for long time in my target system
But when I try to use ffserver and ffmpeg to do the same thing,

the system is not stable for a few minutes.
the system will freeze after a few minutes.
Does someone have idea about the stable issue?
