stxnext.transform.avi2flv 0.2.1

Converts clips from AVI format to FLV during upload to Plone.

Overview

Converts clips from AVI format to FLV during upload to Plone.

It is fairly easy to turn on conversion from other video formats - more information in section “Configuration”.

Requirements

This package uses FFmpeg. You need to install it in you system.

On Ubuntu 9.04 you have to execute:

sudo apt-get install ffmpeg libavcodec-unstripped-52

On CentOS 5.3 command is even simpler:

sudo yum install ffmpeg

On other linux system compile FFmpeg with flv and mp3 support.

Installation

If you are using zc.buildout to manage your project, you can do this:

• Add stxnext.transform.avi2flv to the list of eggs to install, e.g.:

  [buildout]
  ...
  eggs =
      ...
      stxnext.transform.avi2flv

• Re-run buildout, e.g. with:

  $ ./bin/buildout

Finally go to ‘Site Setup’ -> ‘Add/Remove Products’ and install stxnext.transform.avi2flv.

Usage

AVI clips will be automatically converted, so no special attention by editor is needed.

Configuration

Options for FFmpeg that controls quality of output video can be configured via ZMI (portal_transforms -> avi_to_flv).

With default configuration it will execute command similar to:

ffmpeg -i "input.avi" -y -b 1024k -r 25 -acodec libmp3lame -ar 44100 'output.flv'

Description of these options and more control parameters you can find in FFmpeg manual.

To turn on conversion from other video formats than “avi”, you need to add more mimetypes into “Input” property of avi_to_flv transformation.

We made simple tests with formats:

• video/x-ms-wmv

• video/mpeg

• video/quicktime
