[Xerte] Inclusion of close captions on video filesanduseofplaylists

Mon Mar 23 12:35:15 GMT 2009

Hello Julian,

Thanks for the offer of help.

The basic functionality that I am hoping to achieve is to be able to
offer the end user a play list which allows the user to select to run
the whole movie (set of flvs) from the start, or to play any specific
flv from the play list. Each flv that comprises part of the overall
movie has its own close caption file. The user is then able to select to
turn close captions on or off. 

With my current limited knowledge of Flash and Xerte I would have more
chance of calling the jwflv player than trying to develop the
functionality it already offered, however I can appreciate that a
solution that was more integrated into Xerte would be better e.g. an flv
player object that could receive a play list xml file that in turn
contained all the details of the flv files and close caption files to
call.

For me it is very early days, both with Xerte and with ActionScript, so
please understand if things go quiet for a while on this one. But once I
can get my head around Xerte and Actionscript I will return to it.

Kind regards

Johnathan

Yes, it could be done, I am sure. I'd be happy to provide some support
to ayone wanting to have  go at it, but I'm a bit busy to take it on
myself at the minute. Presumably if you could play FLVs and give them
captions etc, you woulnd't need the JW player? Just build a similar
solution in Xerte? There would be little point in recreating the JW
player, if that's all that's required, but if you wanted to integrate
more sophisticated FLV support with alll the other features of Xerte
then it might be worth it.

Ulimately what would be great is to have a 'captionFile' property on the
Movie icon, point it to a caption file, and then have the movie icon
fire an onCaption event everytime a new caption point is encountered...

Hello Julian,

The JWFLV video player uses an xml configuration file, an xml playlist
file (which identifies the flv file and the close caption file to play
for each entry in the playlist) and separate xml close caption files
which are in a format unique to the JWFLV player. The makers of the
jwflv player supply a module that can be loaded into subtitle workshop
(free software) to generate the close captions in the necessary format.
If you have other software e.g. aegissub (also free, but which I found
easier to use than subtitle workshop) then you can output close caption
files in the .ass format. Subtitle workshop can import these and then
convert them to JWFLV format.

>From what you say I suspect it would be achievable to call the jwflv
player from within xerte. 

I have been able to set up both coldfusion code and php code to call the
flvplayer and pass it the necessary parameters, so I guess it is now
down to my improving my action scripting and understanding of Xerte.

I am looking forward to your forthcoming online tutorial on Friday 3rd.
I may not be able to be there live, but there's always the recording :-)

Kind regards

Johnathan

The play list is just an xml file, so Xerte could easily enough load it
and create a list of items, that when clicked loaded and flv into the
player. 

Synching up the display of captions to the playback of the video would
mean tracking the current playhead time in the video and showing the
caption. I assume that the caption file is also xml, something like
this:

<captions>

  <caption time="00:12"><![CDATA[Here is a caption</caption>

</captions>

Which is all the inforamtion you'd need to also support them,

Prior to looking at Xerte I have been experimenting with the jwflv
player, which is free for non-commercial use and has a modest licence
fee for commercial use.

This is flash based and allows for the playing of flv files, with
support for the use of playlists and close caption files.

Is there any support within Xerte for the use of playlists or close
caption files?

If not has anyone looked at the possibility of calling the jwflv player
from within Xerte?

Kind regards
