Streaming video from android using ffmpeg

The Haipad uses a ov7670 sensor from which we want to capture video and stream to elsewhere

install Code Sourcery and Cygwin, use the following to build:

export CYGPATH=cygpath # [[https://support.codesourcery.com/GNUToolchain/kbentry46]]

Checkout and configure

git clone git://git.videolan.org/ffmpeg.git ffmpeg
cd ffmpeg
./configure --arch=arm --cross-prefix=/cygdrive/c/sourcery/bin/arm-none-linux-gnueabi- --extra-ldflags=-static --target -os=linux  --enable-cross-compile
make -j4

on device:

mkdir /data/ffmpeg

push:

adb push ffserver /data/ffmpeg

set permissions

chmod 777 /data/ffmpeg/ffserver

running:

cd /data/ffmpeg
./ffmpeg -f video4linux2 -i /dev/video0 -f avi -vcodec mjmpeg tvffmpeg.avi
./ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 webcam.mpg
