looks good...
it should only add a .anx to ogg theora based content. If you look at http://www.urbanstew.org/MediaWiki/index.php5?title=Special:MvExportStream&a... your using media source mv_ogg_low_quality as the id for flv. If you take a look at a metavid roe media description file: http://metavid.ucsc.edu/wiki/index.php?title=Special:MvExportStream&feed... and find the flv source identified by: ao_file_flash_flv. You want to keep both the ogg and flash mediaSources in place so that the client can switch between them.
Since http://www.archive.org/download/mv_senate_proceeding_08-01-07/senate_proceed... will not produce a flv file from 0-20min rather the server will ignore the time request ie we are not using mod_annodex or oggz_chop for flash... we should put the time range as attributes on the media source (since seeking will be done client side the time stamp should be read from the start / end attribute). ie a flash media source line in the ROE file could look like this: <mediaSource id="ao_file_flash_flv" src="http://www.archive.org/download/mv_senate_proceeding_08-01-07/senate_proceeding_08-01-07.flv" title="Archive.org - flash video" content-type="video/x-flv" start="ntp:0:00:00" end="ntp:0:20:00"/>
attached a patch for adding in time attribute to SpecialExport.... (svn commit access is temporarily disabled while the svn system administrator is re-adding everyones rsa_id.pub (since that Debian predictable key vulnerability))
in mv_embed we have to make a few changes....function getParseROE should not die if it only finds flash source. ie line 1131 .. and we need to store all the media sources when we parse the ROE file (instead of just storing .ogg in this.src). A few other will have to be updated as well like getDurration() should read from our internal representation of start/end times instead of parsing the this.src. ( this.start_ntp and this.end_ntp are already set in getDurration just have to update code else ware to use it & make getDuration smart about flash based sources)
The current Stream interface just updates the "this.src" attribute to jump around the stream....To make it work correctly with the Stream interface there should be a mv_embed function to update the current requested time range. (as opposed to just rewriting the src attribute).... With ogg we will continue to just rewrite the &t= url parameter of this.src and with flash or mp4 it will mean updating the client side seeking start end attributes.
Also we should update plugin selection to only allow selection of the flowplayer if a stream of content type video/x-flv is available. Likewise should only allow ogg selection if stream of content type video/ogg is available. In terms of simple usage of the video tag like: <video src="mymedia_url" we should have javascript do a HEAD request to get the content type of the media and act accordingly... (it will have to be proxied if the media is not on the same domain) ... it would not be a bad idea to confirm media types match up between the urls in the roe file and the content type of the url... but this HEAD request stuff can be added later since we won't be worrying about graceful handling of bad roe files for now ;)
hopefully this explanation was helpful... let me know if you have any additional questions :)
peace, --michael

Hello,
I started getting some minimal progress on the Flash video support along the lines of what Michael suggested. You can see an example of pulling an .flv video from archive.org here: http://www.urbanstew.org/MediaWiki/index.php5?title=Stream:Congress
What is implemented so far:
- if your environment supports Flash, Flowplayer should be an option
- you can view an .flv stream using Flowplayer - but all time
information is ignored
Right now, when a stream file is added, metavidwiki system appends .anx to it, so the flashEmbed script takes .anx out of the filename it gets. How should I address this for the long run?
Cheers,
