User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:10.0.2) Gecko/20100101 Firefox/10.0.2 Build ID: 20120215223356 Steps to reproduce: Playing a movie in FireFox that has SCC closed captions does not display the captions. I play this movie in Safari and I get a CC button on the playbar and it displays closed captioning: http://www.personal.psu.edu/pzb4/sam/SOC119_Trailer.m4v Actual results: Playing the same movie in FireFox does not give me the CC button, so no captions are available. Expected results: There should be a CC button on the playbar if SCC captions are available.
The SCC captions were added to the QT movie using Apple's ClosedCaptionImporter.component plugin for QT.
The browser knows nothing about captions, that are Plugin internals. Did you test this with a different browser since Safari uses AFAIK OS X internal interfaces.
Yes, it also does not work in Opera either. I thought since both Safari and FireFox used the QT plugin for the browser that there was some difference in FireFox's implementation of the plugin.
I guess that this functionality isn't available if you use the normal npapi plugin and safari might use some OS internal APIs. The best would be to ask Apple but that seems to me as user like a big black hole.
Thanks for your quick response. I will see what Apple folks have to say.
Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/ If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
