 Chromium.

 The static_pthread_O2.patch does two things.  First, it uses -O2 instead of
 -O3 to build ffmpeg.  This yields a significant savings in binary size, and
 also improve performance (lower CPU usage) on Pentium4 and Core.
 Second, the patch adds a modification that statically links pthreadGC2
 into avcodec-52.dll on an MSYS/MinGW build in Windows.  This reduces the
 number of DLLs required for distribution, and lowers the total size of the
 binaries.
 
 Steps for extracting:
 #  1) Extract ffmpeg-mt, which creates the directory ffmpeg-mt:
+       cd /cygdrive/c/src/chromium/deps/third_party/ffmpeg
        rm -rf ffmpeg-mt
        tar xf ffmpeg-mt.tar.gz
 #  2) Extract libswscale in place:
        cd ffmpeg-mt
        tar xf ../libswscale.tar.gz
 #  3) Apply patches:
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/01_static_pthread_O2.patch
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/02_mov_dref_looping.patch
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/03_mpeg4_video_to_elementary_stream.patch
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/04_vc1_bsfs.patch
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/05_respect_flac_dirac_configure.patch
        patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/06_remove_decode_on_config_no_svq3.patch
        patch -p1 --no-backup-if-mismatch < ../patches/ugly/07_get_bits_overrun.patch
        patch -p1 --no-backup-if-mismatch < ../patches/ugly/08_enforce_theora_oob.patch
        patch -p1 --no-backup-if-mismatch < ../patches/ugly/09_enforce_vorbis_oob_divzero.patch
        patch -p1 --no-backup-if-mismatch < ../patches/ugly/10_aac_oob_read.patch
-       patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/12_vp3_key_frame_after_flush.patch
-       patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/15_mkv_buffer_overflow.patch
+       patch -p1 --no-backup-if-mismatch < ../patches/to_upstream/11_mkv_buffer_overflow.patch
        cd ..
        
 There is also a script "make_src_tree.sh" that automates most of the steps
 above for you.  It is currently only tested on linux.
 
 NOTE: Under Windows it is recommended to use Chromium's MinGW/MSYS environment
 or 7-Zip to extract the archives.  We've experienced issues when using WinRAR.
 
 Since FFmpeg is sandboxed inside the render process, we're only interested in
 building the absolute minimum.
