[Bug 410458] [NEW] Implement transcoding deamons for 480x272 and 640x360 .ogv and .mp4

[Fabricio Campos Zuardi]

Public bug reported:

We need to get at least up to point #4 in the following workflow:

1. Registered user uploads an MTS using the upload form
2. The queue daemon runs and checks that there is a new video waiting to be exported
3. it launches an instance of our pre-bundled amazon AMI on EC2
4. as the ec2 jobs runs, the database model for that video is getting updated according with the status
5. all the initial Free transcodings (4 video versions) are finished
6. uploading to Archive.org starts
7. when the final url for the files from Archive.org is known, update the db and kill the AMI

another note, the name of ffmpeg2theora on the ec2 machine is not
ffmpeg2theora.macosx :)

Here are the bash script to generate this 4 free video versions:

NOTES:
- replace 2009-05_00140_horse-eating-sky-field.mts with the file name from s3 and use an unique name for each video instead of intermediate.avi
- replace the artist parameter on the ffmpeg2theora with the name of the contributor for that file or leave it blank
- replace the title parameter on the ffmpeg2theora with the title given on the upload form, or the original filename(not the s3 key) or leave it blank
- replace the contact parameter on the ffmpeg2theora with the website of the contributor for that file or leave it blank
- replace the output file names with whatever identifier we choose for the files to be uploaded to archive.org

I have updated bug #410439 with the new recipes for the mp4 files, so
they are compatible with the ipod touch and the iphone, the ffmpeg
commands of the comment above are outdated already
