Non-monotonous DecodeTimeStamp

Hi all,

Sorry, I don't know how to report this issue to ffmpeg.

I used ffmpeg-2.8.3 to do live transcode, command line is blow:

./ffmpeg -i rtmp://192.168.1.146:1935/live/CH2-shd -vcodec h264_qsv -profile:v high -preset 4 -b:v 6000k -bf 3 -refs 2 -acodec copy -f flv -y rtmp://192.168.1.146:1935/live/CH5-sd

But at some point, after the MFXVideoCORE_SyncOperation() calls, the DecodeTimeStamp is Non-monotonous.

system:

centos 7.1 3.10.0-123.9.3.32088.MSSr3.el7.x86_64

CPU:

Intel(R) Core(TM) i7-4770R CPU @ 3.20GHz

ffmpeg:

490306490308

Please rename ffmpeg.txt to ffmpeg and upload it to centos 7 system.

Thanks a lot.

If I set b-frames to 0: -bf 0, everything is OK.
