[mythtv] 2019-devel: mythpreviewgen still segfaulting on some h264-progressive recordings

Today's build for Fedora 30: c794391

I have several recordings from iptv, about a month old, that still have 
no previews. They are h264 HD-ish and TTBOMK progressive-scan.

The frontend puts up brief error messages, "E Preview: 11085:"

Last night I ran a deinterlacer script on a 1-hour BBC Four HD 
recording.  It took about 5 hours, and plays well in the frontend and 
also on Peter's leanfront;  the raw recording had a video freeze on 
that, a few minutes in.

But mythpreviewgen for the output segfaults immediately after opening 
the H264 codec.  It says the NVDEC functionality failed, although the 
frontend is using it (after failing on the first run post-installation). 
Previewgen segfaults when the frontend isn't running, too.  And ffmpeg 
decoding in the frontend is fine.

Otherwise, still looking good.
