[FFmpeg-user] screen flicker when reduce desired_video_buffers in ffmpeg

[Soho Soho123]

dears :

We use ffserver as stream server, and use ffmpeg to grap data from uvc
cam. ffmpeg option is list below.

ffmpeg -f video4linux2 -vcodec mjpeg -r 30 -s 640x480 -i /dev/video0
-r 30 -vcodec copy http://localhost:8090/feed1.ffm

when we usc VLC the receive stream data (MJPEG stream), and
if desired_video_buffers is set to 12, then screen on VLC is flicker
very serious. Because memory issue, we should to reduce the value of
desired_video_buffers.
Does any one have any idea?


Thanks!
