Hi everyone,
Now I'm getting yuv frames from a video monitor every second and call 
avcodec_encode_video2() to convert them to mpeg frame. At first 
avcodec_encode_video2() works well, but after about 1 minute, it keeps 
returning -12 as return value.  But what's the meaning of -12?

Any suggestion is appreciated.
