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.”

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

• Syndication is only RSS 1.0 (need RSS 2.0)

• PloneMultimedia suite of add-on products

• ATAudio, ATVideo, ATPhoto

• qRSS2Syndication for podcasting

12

A natural evolution

• CMFAudio (CMF-based)

• ATAudio (Archetypes-based)

• Plone4ArtistsAudio (Zope 3)

19




Why Zope 3?

• Usability - user uploads File and system figures out how to handle it. Easier with Z3

• 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

44




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




Preferred upload solutions• Zip file

• uncompress zip file on server

• Tramline

• bypass Zope and use Apache

• lovely.widget

• Flash-based file upload widget

48




Import Zip file / PloneJUpload

49


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
