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

formats besides MP3 and Ogg

Challenges of large ﬁles
Uploading 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

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

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

What’s next

• Downloads and installs:
• Zope, Plone, PIL, add-on products
