Bug#741132: lives: opening a file makes the program crash

[Yann Dirson]

seen 741132 2.2.0~ds0-1
thanks

I can reproduce this problem in testing, with the mp4 fetched using
youtube-dl from http://www.youtube.com/watch?v=wE3fmFTtP9g

* when run as "lives foo.mp4" I get a dialog telling "LiVES was unable
  to open it" and the terminal window just says "failed"
* when using the File/Open menu, I get the same crash.  More precisely:

Failed to open file - I tried:

 LANGUAGE=en LANG=en "/usr/bin/mplayer" -quiet  -osdlevel 0 -vo png:z=1:alpha  -lavdopts o=threads=4 -noframedrop  -ao pcm:fast:nowaveheader   -mc 0  "WildCat-wE3fmFTtP9g.mp4"  </dev/null

Maybe you are missing a library in mplayer (or it is not a valid media file) ?
avformat detected format: mov,mp4,m4a,3gp,3g2,mj2
/usr/lib/lives/lives-exe: symbol lookup error: /usr/lib//lives/plugins/decoders/zzavformat_decoder.so: undefined symbol: av_find_stream_info


According to
https://lists.ffmpeg.org/pipermail/ffmpeg-cvslog/2011-August/039866.html
LiVES could be trying to use an old API call, but I don't see anything
about that in the libavformat changelog.

I could downgrade to 2.0.6~ds0-2 and open the file through
"File/Open", but still get the same puzzling behaviour when requesting
the file on commandline.
