we'd memset() the codec context to zero, thereby setting audio input to U8
and video to YUV420P. For most video encoders, that actually works, but for
most audio codecs, it doesn't. This patch changes defaults to those set by
avcodec_context_get_defaults() and have ffmpeg figure out the optimal encoding
format itself if not set explicitely (as it does for the non-ffserver-cases
also).

It may fail not only because of an invalid value for the option, but
also for other reasons, e.g. memory problems etc.

Darwin compilers default to PIC on, so -mdynamic-no-pic (which disables it 
again) needs to be added to cflags before enable pic is checked.

Fixes compilation without --enable-shared at least the 10.6 system compiler
for x86-32.
Fixes speed regression on all darwin arches except x86-64.
