Reproduce Steps:
============================================
take one case for example
1. build enc as above lists
2. gst-launch-1.0 -q filesrc location=/media/yami_vc1/SA00059.vc1 '!' 'video/x-wmv,profile=(string)advanced,' width=352, height=288, framerate=14/1 '!' msdkvc1dec '!' videoconvert '!' video/x-raw,format=I420 '!' checksumsink2 frame-checksum=FALSE file-checksum=TRUE plane-checksum=FALSE
3. decoding fails and error message occurs.

error info
ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal data stream error.
Additional debug info:
gstbasesrc.c(3055): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0:

vc1 decoding stream
Comment 2 sreerenj 2018-03-30 00:04:31 UTC 
Use the caps filter: video/x-wmv, profile=advanced, format=WVC1, wmvversion=3, width=352, height=288, framerate=14/1 will make the file playable but crash in the middle. Non-packetized vc1 stream handling to tricky and won't work well with all stream unless we add a lot of parsing stuff in the decoder.

Please keep this bug open but I won't consider this as a high priority bug for now.

BTW, I highly recommend using ".asf" muxed files for vc1 testing.
