video.js captions (not native browser captions) are broken in V5

[OwenEdwards]

In the sample docs/examples/simple-embed/index.html, when non-native captions are used (I'm using Firefox 37 on Windows 7), the captions menu includes the captions setting option. Selecting the english option does not display the captions.

I get a 'downloadable font rejected by sanitizer ... /build/temp/font/VideoJS.eot' error in the console.

The 'downloadable font rejected by sanitizer..." error was a red herring!

With further experimentation, a way to get captions displayed is to use the captions settings to change the font color; if this is done while a caption should be displayed, then the caption appears, otherwise the existing caption is cleared. If you change the color while no caption should be displayed, then nothing happens, and the upcoming captions aren't displayed.

I'm guessing this is due to caption events not getting fired by VideoJS, but that changing the captions settings somehow fires an event which may display the current caption? I'm hoping this gets fixed before V5 is released! @gkatsev, have you taken a look at this?

Wow, that's amazing you found that! Yeah, this will have to be fixed for 5.0.

this also occurs in chrome and safari with flash only and flash first tech orders. Should that be noted as a separate issue?

[gkatsev]

Flash and non-native vtt support is when the emulated captions should come up.
I'll take a look soon.

#2215 should fixe this. Someone want to confirm?

[OwenEdwards]

Confirmed; this is fixed in v5.0.0-rc.6.
