Dear friends,
with your help, I am at a very good point with my installation.
Almost all tagging/transcribing functionality works.
I do have one more question at this time:
When I create a new tag or annotation or transcript, the end time shown in the edit box is
always 0:00:30 and not the actual end time (or duration) of the video, and I have to
update it by typing in the end time and then adjust with the slider.
How can I fix this to show the video's end time by default?
Best Regards
Ioannis

Hi,
Following George's comments, I have worked a bit during the weekend on my
installation.
With the following configuration in apache2.conf I avoided using the
relevant rewrite rules in .htaccess and all seems to work fine
<IfModule mod_actions.c>
ScriptAlias /oggz-chop /usr/bin/oggz-chop.cgi
Action application/ogg /oggz-chop.cgi
Action video/ogg /oggz-chop.cgi
Action audio/ogg /oggz-chop.cgi
Action application/ogv /oggz-chop.cgi
Action video/ogv /oggz-chop.cgi
Action audio/ogv /oggz-chop.cgi
</IfModule>
Yup, this one of the two other ways to trigger oggz-chop handing. I think
AddHandler should work as well.
However there is an important difference in that the above example will
send all Ogg multimedia through oggz-chop whereas the RewriteCond
statement in .htaccess will only trigger oggz-chop if there is actually a
query string present. Without a query string the media is delivered as a
static file (w/ HTTP Range request support).
This difference affects at least three things: a) md5sum "correctness," b)
load times, and c) client-side seeking performance.
For a) oggz-chop can and does rewrite some of the header metadata and can
even omit "extra" Ogg streams listed in RFC3533. Thus, a file uploaded to
the server will differ from the same one downloaded; consecutive downloads
will also differ slightly.
For b) the current implementation of oggz-chop starts at byte 0 on the
media and reads all bytes into memory until the specified time ranges are
satisfied; once this is completed the media is then sent through Apache to
the client. For ~1GB recordings read off of a non-SSD drive the delay can
be around 8 seconds or so. A search algorithm that reads the first few
Ogg packets, generates a bitrate, uses this to jump-to the approximate
byte range of interest, and bumps forward/back as needed shouldn't be
'hard' to implement -- patches welcome?
On the plus side subsequent requests are read from memory (=temporarily
fast access) and the Oggz codebase is mostly bullet-proof from a security
perspective. The folks in #theora are friendly and highly knowledgeable.
For c) some browsers (e.g., Firefox) implement "fast" seeking based on
byte range requests on raw media. I'm not entirely sure how well this
interacts with oggz-chop other than to say that a well-trimmed video
segment (i.e., a 10-min clip delivered w/ oggz-chop and a query string)
sidesteps the need to do client-side seeking.
I also created two new pages in mediawiki to
cater for the relevant input
fields when tagging/annotating a video.
Property:Bill
&
Property:Speech By
I created [[Property:Speech by]] with [[has type::page]] myself.
With the above modifications, I can add new videos and then edit them by
adding tags/annotations and transcripts.
A few more questions :
A)
I add a new video from special pages -> metavid add stream
I edit the stream and add the video file, also typing in its length, i.e.
0:10:00
'Duration' listed in the 'Editing Stream:' view should be entered as
total
length in seconds, without punctuation.
However the video (and all videos imported) show
a time length of 0:20:00.
Any suggestions on how to make the video pages show the actual video
length?
Append '&view=overview' (or, if using Short URLs, '?view=overview')
to the
URL to arrive at an "overview" of the meeting with the entire duration
displayed. In this view transcripts are shown in logical "chunks" -- for
example, the entire Q&A portion of a meeting would be be collapsed into a
single block right after a "closing remarks" block.
To enable AJAX 'Date range' search functionality the 'date_start_time'
property of the 'mv_streams' MySQL table should match the UNIX timestamp
of the start of the meeting. The only way I know of entering this data is
by editing the backend DB directly w/ phpMyAdmin.
B)
It seems that I am not able to create a Sequence. From the demo video of
metavid, It seems that by using a Sequence:ABCD you can create a sequence
where videos can be edited in the timeline.
How can I enable this?
Take a look at the following:
http://openmeetings.org/w/js2/mwEmbed_rev115787/example_usage/
The Sequencer is more of a standalone component of mwEmbed at this point,
I think?
C)
In the new transcript part of editing, there seems to be an image of the
person making the speech. In my case its always the missing person.jpg.
How can I add my custom picture?
1) Create [[Template:Person]] with the following:
<div id="profile"><p>{{ #if: {Image:{{PAGENAME}}.jpg}|
[[Image:{{PAGENAME}}.png|80px]]
|}}<span>{{#external_value:title}}. {{PAGENAME}}
</span></p></div>
2) Create/upload [[File:Firstname_Lastname.jpg]] and
[[File:Firstname_Lastname.png]] with a 80?99 .jpg/.png images of the
person.
3) In segment edit view, enter Speech by: -> Firsname Lastname such that
the wikitext contains [[Speech by::Firstname Lastname]]. Do a hard page
refresh as needed.
Cheers,
George
I do have more questions, but I thinks the above are quite enough for now
:)
Best Regards
Ioannis

One more update...
In the add annotatio or tag box, I do not see the video time slider on the
top of the edit box.
I believe there is something wrong with my mvembed, perhaps I need another
version?
There are differences between version of both MetaVidWiki and mwEmbed.
Try upgrading/downgrading mwEmbed, yes, but don't be afraid to upgrade
MetaVidWiki itself -- there's no recent DB schema changes so it's really a
matter or replacing files in the extensions/ directory and re-applying any
customizations.
At the moment
OpenMeetings.org runs MetaVidWiki rev. 51560 and mwEmbed
rev. 51518. Your mileage may vary but I do recommend monitoring Firebug
for errors, esp. with the most-recent versions.
==
I forgot to mention that Extension:OggHandler and MetaVidWiki require a
working copy of FFmpeg and now would be a good time to check it's in good
working condition. My build (circa mid-2009):
FFmpeg version SVN-r19749
configuration: --disable-demuxers --disable-muxers --disable-decoders
--disable-encoders --disable-ffserver --disable-ffplay
--enable-encoder=mjpeg --enable-muxer=mjpeg --enable-decoder=theora
--enable-demuxer=ogg --disable-network --disable-devices
--disable-parsers --enable-parser=vp3
Sincerely,
George

My new problem is with the Sequence part of the wiki, which has the
following problem:
A new sequence is created
A video file is added to the sequence
Attempting to switch to visual editor shows the visual editor window but
does not produce any output, instead it shows for ever "Loading

Ah, I show the same. No idea -- I've never used it.

Dear friends,
following the much appreciated support from Michael and George, I finally
managed to install and configure a working platform consisting of the
following elements:
Mediawiki 1.16a r52874
PHP 5.3.2-1ubuntu4.18 (apache2handler)
MySQL 5.1.41-3ubuntu2.10
Cite (Version 2008-01-31)
ParserFunctions
RSS Reader (Version 0.2.3)
Semantic MediaWiki (Version 1.3)
OggHandler (r42524)
MetaVidWiki (Version 1.0r47961)
Essentially, the platform is the same as the one on
metavid.org site.
I am now able to add new streams and tag / transcribe them.
My question though has to do with uploading new video content to the site.
I have setup all the relevant variables for allowed extensions, file size
uploads,etc. If I upload any type of allowed content (i.e. mp4 video, word
document, jpeg image) the upload is completed and the new content is
available.
However, if I try to upload an ogg or ogv file, either directly or by
transcoding it by fireogg plugin, the upload does not complete. No errors
are produced in the web server or other system logs.
Any suggestions on what to look for in order to resolve this ?
My current way of uploading content is to copy the file to a folder on the
web server and then use the add stream to create a stream and reference to
the video file.
Also, is there any batch upload / import method available?
Regards
Ioannis
