 mythpreviewgen crashes for me in master.

 The installation is one with a very long history of upgrades and it might
 well be a setting that is wrong. Bet there should still not be a crash :-)

 Running under gdb gave me the crash line:
 #0  0x00007ffff4e5f6bd in AvFormatDecoder::H264PreProcessPkt(AVStream*,
 AVPacket*) (this=0x6eda90, stream=0x716e40, pkt=0x7fffa40037e0) at
 avformatdecoder.cpp:3465

 The line is:         if ((AVMEDIA_TYPE_VIDEO == enc->codec_type) &&
                     (kCodec_H264 == video_codec_id) &&
                     (enc->codec) && (enc->thread_count>1))

 And sure enough enc returned from previous line is NULL. Perhaps a check
 and an error message?

 Tell me what logs etc. you might need to sort this out!
