<div class="gmail_quote">Hi guys, I have been using gstreamer for some time now & found it to be a great tool. My issue is when I am muxiing the H264 data using mpegtsmux it gives corrupted TS data. i am pushing h264 encoded frames using appsrc plugin. Although it works fine at lower bitrate like 300-400 kbps. it gives corruted data stream at 2-3Mbps. appsrc->queue->mpegtsmux->filesink the same pipeline creates proper file at low bitrate. when i run this file with vlc or ffplay they report error as follow. vlc- mb_type -6 in P slice too large at 2 33 error while decoding MB 2 33 mb_type 106 in P slice too large at 5 4 error while decoding MB 5 4
