What is podcasting?

• From Wikipedia:

• “Podcasting is the distribution of audio or video files, such as radio programs or music videos, over the internet using either RSS or Atom syndication for listening on mobile devices and personal computers.”

5


Podcasting is growing

• FeedBurner now distributes 47,000 different podcasts, which means there are more podcasters than radio stations.

• The rate at which new podcasters emerge on the scene has doubled in the last six months.

10


Projections

• The Diffusion Group forecasts that the use of podcasting among U.S. consumers is growing at a compound annual rate of 101 %

• By 2010, 56.8 million Americans will be using “time-shifted digital audio files” or podcasts

Why Zope 3?

• Pluggability - easily extend to support other formats besides MP3 and Ogg

• Reusability - abstracting the code into Zope 3 components means it is easier to reuse

Challenges of large filesUploading and Storing

45


Pain points

• Uploading large files is tedious

• ZODB is currently not designed to store large files

46


Making upload less tedious

• WebDAV/FTP

• gives you progress bar but it can be buggy

• PloneJUpload - java applet

• not all browsers have Java support

47

PloneJUpload

Preferred upload solutions

• ZipFileTransport

• upload a Zip file and it’s extracted on the server

• PloneFlashUpload

• upload multiple files using Flash widget in browser

• Tramline

• bypass Zope and use Apache

PloneFlashUpload


Why store media on FS?

• Avoid ZODB bloat

• Expose to 3rd party streaming software

• Easier to backup or move to another system

• Transcode video files

50


Alternative storage layers

• FileField(‘mediafile’, storage=...)

• ExternalStorage

• used on plone.org’s PloneSoftwareCenter

• FileSystemStorage

• used by Andreas Jung for large media project

51


Alternative file field• BlobFile

• dependent on blob

• ATTramline

• dependent on Tramline

• AttachmentField

• new version has FlexStorage

• PLIP #154 - Large File Handling

• http://plone.org/products/plone/roadmap/154

52

Preferred solutions

• ZODB with blob support

• Now working on Zope 2.9 / 2.10 / 2.11

• Use with ATBlobField from Enfold Systems

• Amazon S3

• scalable storage solution

• pay for what you use
