Description
Hello,
FLV doesn't work any more since last versions of Wordpress.
I have this error : NetworkError: Exception ProgressEvent error when I use this code in articles :
[video width="640" height="480" flv="http://mydomaine.org/wp-content/uploads/2012/02/DSC_0011.flv"][/video]
and sometimes this error : "Aucune vidéo dont le format ou le type MINE est géré n'a été trouvée"
Thank you for your help

- Component changed from General to Media
Hmm, I was thinking it was caused by removing the Flash files in r42462 (for #42720), but those shouldn't be needed for those browsers. Even if they were, installing that plugin should have resolved that.
I'm not sure what else it would be, though. Can you provide the real URL, so that I can try to reproduce it myself?
Did you upgrade any plugins at same time? If so, what are they?

Hmmm, I've done a bunch of testing, but have only come up with more questions.
I tested a local copy of the Taxi.flv video from comment:4 and guqin.flv from MediaElement's demo. I used a Windows 7 VM, with IE 11 and the latest versions of Chrome and Firefox. All 3 had Flash installed.
There are several variables at play here:
- The WP 4.8.x -> 4.9.x upgrade replaced MediaElement 2.x with MediaElement 4.x
- The WP 4.8.5 and 4.9.2 updates removed the SWF files from MediaElement 2.x and 4.x
- Browser support for FLVs, particular codecs, etc.
- Maybe the FLV encoding or other characteristics.
File | Browser | WP Version | SWF used | Works |
---|---|---|---|---|
Taxi.flv | Firefox 57 | 4.8.4 | Yes | Yes |
Taxi.flv | Chrome 63 | 4.8.4 | No | No |
Taxi.flv | IE 11 | 4.8.4 | Yes | Yes |
Taxi.flv | Firefox 57 | 4.8.5 | Yes | No |
Taxi.flv | Chrome 63 | 4.8.5 | No | No |
Taxi.flv | IE 11 | 4.8.5 | Yes | No |
Taxi.flv | Firefox 57 | 4.9.1 | No | No |
Taxi.flv | Chrome 63 | 4.9.1 | No | No |
Taxi.flv | IE 11 | 4.9.1 | Yes | Yes |
Taxi.flv | Firefox 57 | 4.9.2 | No | No |
Taxi.flv | Chrome 63 | 4.9.2 | No | No |
Taxi.flv | IE 11 | 4.9.2 | Yes | No |
guqin.flv | Firefox 57 | 4.8.4 | Yes | Yes |
guqin.flv | Chrome 63 | 4.8.4 | No | No |
guqin.flv | IE 11 | 4.8.4 | Yes | Yes |
guqin.flv | Firefox 57 | 4.8.5 | Yes | No |
guqin.flv | Chrome 63 | 4.8.5 | No | No |
guqin.flv | IE 11 | 4.8.5 | Yes | No |
guqin.flv | Firefox 57 | 4.9.1 | No | No |
guqin.flv | Chrome 63 | 4.9.1 | No | Yes |
guqin.flv | IE 11 | 4.9.1 | Yes | Yes |
guqin.flv | Firefox 57 | 4.9.2 | No | Yes |
guqin.flv | Chrome 63 | 4.9.2 | No | Yes |
guqin.flv | IE 11 | 4.9.2 | Yes | No |
These things stood out to me:
- IE 11 needs the SWF fallbacks to play FLV videos. I think I missed that in researching the safety of removing the SWF files in the latest release.
- Both IE and Firefox stopped working in the update from 4.8.4 to 4.8.5, because they were trying to use the SWF. Based on the above, that's expected for IE, but it shouldn't be necessary for Firefox, which has native support for FLVs. You can see that working in MediaElement's demo, even without Flash installed.
- Chrome only worked with
guqin.flv
in WP 4.9.x. So, it only worked with MediaElement 4.x, but not in 2.x. It should work in both. It also has native support for FLVs (again, see the MEjs demo). - Chrome never worked with
Taxi.flv
, even with MediaElement 4.x. Maybe there's something about the way it's encoded that Chrome doesn't like? guqin.flv
works in Firefox with WP 4.9.2, but not with 4.9.1. That doesn't make any sense, based on the variables listed above. The WP 4.8.5 and 4.9.2 updates did remove some MediaElement 4.x renderers for 3rd-party hosting platforms and language files, but that shouldn't affect anything.
@Fred001, let me know if anything above gives you any clues as to what the problem is.
It'd also be helpful to learn the specific WP version where your videos stopped working. You could try temporarily downgrading to 4.9.1, then test the video, then 4.8.5 and test, then 4.8.4 and test.
Also, does guqin.flv work on your site? It may be important to upload a copy to your site, rather than embedding the remote video, to test your web server's MIME type configuration.

Hi,
I generate an article with your guqin.flv here :
https://famillemathy.fr/2018/01/20/test2/
In this article :
[video [video width="640" height="480" flv="http://famillemathy.fr/wp-content/uploads/2018/01/guqin.flv"][/video] -> doesn't work
[playlist type="video" ids="18281"] -> works
and
https://famillemathy.fr/2018/01/20/test-2/
In this article :
[video width="640" height="480" flv="http://famillemathy.fr/wp-content/uploads/2012/07/Taxi.flv"][/video] -> doesn't work
[playlist type="video" ids="2126"] -> doesn't work

I downgraded to :
4.8 -> ok for taxi.flv
4.8.4 -> ok for taxi.flv
4.8.5 -> doesn't work for taxi.flv
Fred
Where do you see that error? In the browser's console?
What web browser are you using?
Does installing the MediaElement Flash Fallback plugin fix it?
