[Live-devel] streaming big H264 I frame out, image broken

[Eric_Hsieh at alphanetworks.com]

Hi Ross,

Yes, you are right, set it as 0, the delay is gone. Thanks.

One more question, streaming with high bitrate(4M or 8M), ffplay will show following.
Do you have any suggestions we can do on server side? Thanks a lot.
