4dfb74cd4f Flush decoders correctly in avformat_find_stream_info().
The decoders should not only be flushed on EOF or error, but also when
e.g. probe size was reached.
It is best to just always flush by default and only disable it
explicitly when we know that we have everything we need.
Fixes trac ticket #879.

f907615f08 parsers: initialize MpegEncContext.slice_context_count to 1
The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly)
a MpegEncContext in their private context. Since they do not call the
common mpegvideo init function slice_context_count has explicitly set
to 1.
Prevents a null pointer dereference in the h264 parser and fixes
bug 193.

Author: Mans Rullgard <mans@mansr.com>

    	x86: cabac: replace explicit memory references with "m" operands

    	This replaces the explicit offset(reg) memory references with
    	"m" operands for the same locations.  As a result, one fewer
    	register operand is needed for these inline asm statements.

This change appears to have broken compilation on darwin, and subsequent
fixes by martin (which did not fix compilation) removed the register
advantage, thus this change seems not a good idea to keep.

acb074301c avio: Only do implicit network initialization for network protocols
The implicit network initialization is set to be removed in the
future, but is kept for compatibility. By not doing the implicit
initialization for non-network protocols, we avoid the warning
about avformat_network_init() not being called for these, where
it really doesn't make much sense.

1d0d63052b sipr: fall back to setting mode based on bit_rate.
Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.
