Download ffmpeg-0.6.1

Mount the patch file mv to the ffmpeg-0.6.1 directory

Patch

Patch-p1 <ffmpeg-0.6.1_libvpx-v0.9.5-135-gc28b10a.diff

First, compile and install libvpx

The configuration file is./configure -- prefix =/usr/local/libvpx -- enable-shared -- enable-vp8

Cross-compilation Configuration

./Configure -- target = armv6-linux-gcc -- prefix =/usr/local/libvpx-arm -- enable-shared -- enable-vp8

Error message: yasm

Solution: sudo apt-get install yasm

Make

Sudo make install

Compile and install ffmpeg

The configuration file is

. /Configure -- prefix =/usr/local/ffmpeg-vp8-x86 -- enable-libvpx -- enable-shared -- cc = gcc -- extra-cflags =-I/usr/local/libvpx/include -- extra -ldflags =-L/usr/local/libvpx/lib
