gst-bad 		master branch 0bdcf51baf77926b4f29c01a2fdf133c13aad62e

Reproduce Steps:
============================================
take one case for example
1. build enc as above lists
2. gst-launch-1.0 -f filesrc location=/media/encoderbitstreams//720p5994_parkrun_ter.yuv '!' videoparse format=i420 width=1280 height=720 framerate=30 '!' videoconvert '!' video/x-raw,format=NV12 '!' msdkmpeg2enc rate-control=cqp qpi=26 qpp=26 qpb=26 gop-size=30 b-frames=0 '!' mpegvideoparse '!' mpegtsmux '!' filesink location=./720p5994_parkrun_i420_profilemain_rc0_ip_qp26_slice1_gop30_fps30.mpg
3. gst-launch-1.0 -f -q filesrc location=./720p5994_parkrun_i420_profilemain_rc0_ip_qp26_slice1_gop30_fps30.mpg '!' mpegvideoparse '!' msdkmpeg2dec '!' videoconvert '!' ximagesink

2. gst-launch-1.0 -f -q filesrc location=./720p5994_parkrun_i420_profilemain_rc0_ip_qp26_slice1_gop30_fps30.mpg '!' mpegvideoparse '!' mfxmpeg2dec '!' videoconvert '!' ximagesink


mplayer ./720p5994_parkrun_i420_profilemain_rc0_ip_qp26_slice1_gop30_fps30.mpg

use mfx instead of msdk, it also has garbage
use mplayer to play the encoded file, the file can be palyed clearly.
Comment 2 U. Artie Eoff 2018-06-06 02:53:33 UTC 
If using mpegtsmux during encode, you need to use tsdemux before mpegvideoparse in decode pipeline.
Comment 3 U. Artie Eoff 2018-06-06 03:06:55 UTC 
Or just remove mpegtsmux from encode pipeline
Comment 4 zj,wang 2018-06-06 05:39:20 UTC 
 The option "mpegtsmux" should using conjunction with "tsdemux", after remove "mpegtsmux" from encode pipeline, this issue can not be duplicated, so close it.
