HTML5 player does not change captions using setKDPAttribute('closedCaptions','ccUrl','http:/machine.domain/file.srt')
Wed, 12/28/2011 - 12:55
i'm going to prepare a test case tomorrow but meanwhile...is html5 player ABLE to change ccUrl by javascript?
i've tested i can change captions with this code using kdp3 flash but it does not work for me with html player.
function jsCallbackReady(playerId) {
window.kdp = $('#' + playerId).get(0);
kdp.addJsListener("changeMedia", "mediaChangeHandler");
}
function mediaChangeHandler(data,id){
//$('#notifications').text($('#notifications').text() + '\n' + data.entryId);
$('#mykdp').get(0).setKDPAttribute('closedCaptions','type','srt');
$('#mykdp').get(0).setKDPAttribute('closedCaptions','ccUrl','http://machine.domain/' + data.entryId + '.srt');
}
window.kdp = $('#' + playerId).get(0);
kdp.addJsListener("changeMedia", "mediaChangeHandler");
}
function mediaChangeHandler(data,id){
//$('#notifications').text($('#notifications').text() + '\n' + data.entryId);
$('#mykdp').get(0).setKDPAttribute('closedCaptions','type','srt');
$('#mykdp').get(0).setKDPAttribute('closedCaptions','ccUrl','http://machine.domain/' + data.entryId + '.srt');
}
thx in advance

Thx Michael. I've tried to use new captions concept but it breaks totally my use case. Maybe i'm not catching the point but with eagle captions style IS NOT POSSIBLE to have srt generated on the fly wich I need to generate a srt with several strings customized.
Look at this communication with kaltura support
Case# 00007558: Options for captions not showed to me at KMC:
"Thx XXXX, you have explain it clearly but i've not explained myself enough.
The cause is that the srt is ingested and cached by kaltura server
"you will see the URL converted to a Kaltura URL - Kaltura ingested
the SRT file to our servers." and it is not what I need, i want to
generate the srt each time the video is played as that file is builded
with per-user specific content.
For example http://mimachine.midomain/customsrt/rich_at_argonauta_org.srt
is going to serve a file with specific messages for that user.
"
Support group has suggested me old captions because of this. ufff I expect that Kaltura will include caption custom urls in their main develop stream or that business case is going to break!
thx and happy new year!

Sounds like a legitimate use case. We should update html5 to support that api. Will try and touch on this today. Will keep you updated.

Should be fixed in trunk and for the 1.6.2 release.
See this page for more release details: http://html5video.org/wiki/Kaltura_HTML5_Release_Notes

Thx! Tested against 1.6.2, all OK
Question: I've got a "ResourceLoader ::Could not save file to cache" error at console javascript, I guess it's related with not been able to write to kaltura.org filesystem. Do I need to be able to write to cache for html5 library to work properly? Is there an easy way to set $wgScriptCacheDirectory to my file system?

fixed the cache issue. thanks
I will try and take a look at this tmw or the next day. We just need to do a small adjustment to add support for this to html5 captions so you can treat the kdp the same in html5 and flash.
The reason this is not already supported is later versions of kaltura platform support captions as a first class citizen associated with assets so there is less need to manually change captions.. but either way its not complicated to include the older way support as well.
