 Recently, I noticed a server halting. mythbackend on preview generation
 took up all memory. Upon further inspection, both mythtranscode and
 mythcommflag do the same.

 mythcommflag on a 20MB sample stream eats up 120MB of memory - for full
 recordings, the system runs OOM. Of course, I tried to "rebuild"
 seektables, but the bug seems to be "before" that.

 From valgrind's/massif's output, it seems that from
 AVFormatDecoder::!OpenFile on, av_malloc'ed and av_mallocz'ed memory is
 never freed.
