Facebook app on Android – Video file not found

[Solved]

Foliovision › Forums › FV Player › Bug Reports › Facebook app on Android – Video file not found

  • Davide 6 years, 5 months ago

    Hello Martin, how are you?
    Please, first of all, remove all public link from this thread.
    We have a very strange issue here: it happens only on Android platform (all Android platform) and Facebook app (so I mean: Facebook on Chrome or other browser works fine).
    Video loaded with Facebook app browser fails (only on Android), error message is:

    html5: Video file not found
    Couldn’t find the required video type: video/fv-mp4

    We did try with and without preroll ADV. Audio is not available in all cases. With preroll… you can see preroll video but not the following video. Without preroll you can see the video (but without audio), so I suppose first video is always displayed (but without audio in all cases).
    You could try here: (please remove) choose one of video post.

    May you please take a look and save us?

    Thank you

    Hello Davide,

    please check the user agent string of your Facebook for Android app. You can do so by sharing a link to https://www.whatsmyua.info/ on Facebook and then opening that in your Facebook app.

    My guess is that it’s some old version of Google Chrome, in the worst case we need to stop these video ads on it altogether.

    I have seen some playlists on your website – do these play fine in Facebook app when you disabled the video ads? Can you play any of the items, or is it always limited to the first item only?

    Thanks,
    Martin

    Hi Martin,
    unfortunately User-Agent string won’t be useful. It happens with ALL Android devices (One Plus 6, Honor, Huawei…), on Facebook App Browser (so, not Google Chrome as you wrote, I thought I was clear in my previous post, sorry it’s my bad english).

    As I wrote, it happens with AND without ADS:

    1) with pre-roll: you can see the video ads, you can’t heard audio, you can’t view the video.
    2) without pre-roll: you can see the video, you can’t heard audio.

    I hope I was clearer.

    Hello Davide,

    the web browser in Facebook app seems to be just an old version of Google Chrome. That’s what I mean, I understand that you are using Facebook app and not Chrome. There is no problem with your English, I’m not a native speaker either.

    I’ll get it installed and see what I can find. I guess it will be the same version as what you have.

    Thanks,
    Martin

    Hello Davide,

    so it’s actually the most recent Chrome version. I tried it on my onw phone and I go the same version 71.0.3578.99.

    I was able to reproduce the same issue on https://foliovision.com/player/demos/roll-custom-video -> “VIMEO VIDEO WITH ANOTHER VIMEO VIDEO IN PRE-ROLL”. Sometimes it played fine, sometimes it failed to play the video after the ad. But the sound was always off, so I always had to unmute it.

    No issues in original Google Chrome, not even after I upgraded it to the same version as what the Facebook app is using.

    Problem with the Facebook app is that its built-in Chrome browser doesn’t support remote debugging..

    Thanks,
    Martin

    E mo’ che facciamo? :-D

    It means: and so now? Any idea / workaround? Any chance to solve the issue?

    My best

    Hello Davide,

    please post https://foliovision.com/debug/ privately using Facebook and the go to it using the Facebook app and let us know how it works for you.

    We disabled HLS.js and Dash.js libraries for Facebook browser there and it seems to help. Let us know about your experience please.

    Thanks,
    Martin
