Hmm, no behavior change or security issue, just better log output.

This is what I saw:

[libx264 @ 0x1d55140] profile High, level 3.1
[libx264 @ 0x1d55140] 264 - core 124 r2198 1c97f35 - H.264/MPEG-4 AVC codec - Copyleft 2003-2012 - http://www.videolan.org/x264.html - options: cabac=1 ref=5 deblock=1:0:0 analyse=0x3:0x113 me=umh subme=8 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=6 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=2 b_bias=0 direct=3 weightb=1 open_gop=0 weightp=2 keyint=250 keyint_min=2Output #0, matroska, to '20110907-0.mkv':

The x264 parameters are truncated (in particular, I missed verifying my
crf setting) and the 'Output #0' is shifted due t the missing newline.
