Intel MSDK MPEG 2 Decoder Problem

HtGst

Hi

Built gstreamer 1.12 (Base, Good, Bad, etc.) from source and ported
gstmsdkmpeg2dec.c from master branch to be able to decode mpeg2. It
builds fine; however, there are noticeable visual artifacts at bottom
right of the decoded video. Just wondering if this  is a known issue
(hopefully with a solution)?

CLI:

gst-launch-1.0  udpsrc name=udpsrc uri=udp://localhost:9000 sync=TRUE
do-timestamp=true caps="video/mpegts, systemstream=(boolean)true,
packetsize=(int)188" ! \
         queue name=qtsparse ! tsparse name=tsparse set-timestamps=true  ! \
         queue name=qtsdemux ! tsdemux name=tsdemux emit-stats=false
parse-private-sections=true !  \
         queue name=qvideoparse ! mpegvideoparse name=mpegvideoparse
gop-split=true ! \
         queue name=qdec ! msdkmpeg2dec name=dec  ! \
         filesink location=cap.raw

Cheers,

Could you try with current master, or the 1.14 pre release?

There's has been a lot of work on msdk lately.

Thanks Victor. Will give it a try. For now, I am using Ishmael's fork,
https://github.com/ishmael1985/gstreamer-media-SDK, for decode and vpp.
(It has problems with hevc encode, though.)
Cheers,

lol. Sorry, if text wasn't clear. It meant to say that msdkmpeg2enc is not functioning properly, not mfxmpeg2enc, which is
working beautifully.(Haven't had a chance to try 1.14 yet.)

Msdk plugins are still under heavy development.
Please file a bug to track the issue.
