0393cf15db Revert "Acquire lock when initializing parsers."
This reverts commit 7feef7dbca.

This commit causes assertion failures due to use of parser_init from multiple
threads, for example indirectly by ffmpeg.c and more directly from the
packet read functions.

I dont know how to fix this quickly, and fixing ffmpeg.c leaves
the possibility of other applications being affected.
Crashing the applications until this is resolved is clearly no good
thus this revert, so we have time to think about the problem.

Crashes can be reproduced by using multiple input files in ffmpeg.

Signed-off-by: Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>

Modify the parser initialization so that parsers can
set pict_type themselves.  Use this in the mpegvideo parser
so that initial frames are not unconditionally I frames.
I have had this in my tree for several years.
