Jaksta youtube WEBM video encoding fix (Bash and PHP versions of script)

readme

Yoy should use only one of above files.
Scripts writen in different languages, but do the same work. Of course, for using ffmpeg.php you must have instlalled php.

Go to Jaksta ffmpeg dir:
# cd /Applications/Jaksta.app/Contents/Frameworks/ShedConverter.framework/Versions/A/Resources/

Rename original ffmpeg. Just store it. It never be used.
# mv ffmpeg ffmpeg-jaksta-origin

Download last release of ffmpeg http://ffmpegmac.net/ and unpack it. For example new ffmpeg binary will be in ~/Downloads/ffmpeg

Copy new ffmpeg bynary to Jaksta directory as ffmpeg-bin(we still in Jaksta ffmpeg directory)
# cp ~/Downloads/ffmpeg ffmpeg-bin

Copy on of above files to /Applications/Jaksta.app/Contents/Frameworks/ShedConverter.framework/Versions/A/Resources/. For example, file in ~/Downloads/ffmpeg.sh
# cp ~/Downloads/ffmpeg.sh /Applications/Jaksta.app/Contents/Frameworks/ShedConverter.framework/Versions/A/Resources/ffmpeg

So, we must have files:
/Applications/Jaksta.app/Contents/Frameworks/ShedConverter.framework/Versions/A/Resources/ffmpeg
/Applications/Jaksta.app/Contents/Frameworks/ShedConverter.framework/Versions/A/Resources/ffmpeg-bin

When Jaksta run task to join splitted sources, our ffmpeg transfer fixed arguments to ffmpeg bynary.
