Subject [jira] [Resolved] (CB-8798) Android 4.x - HTML5 video tag only audio playing

Joe Bowser resolved CB-8798.
----------------------------
    Resolution: Cannot Reproduce

I can't reproduce on any device I test on with the Big Buck Bunny code on quirksmode.  Your
video file is down, which makes me think that this is a codec issue, and not a cordova issue.

>                 Key: CB-8798
>                 URL: https://issues.apache.org/jira/browse/CB-8798
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Android
>    Affects Versions: Master
>         Environment: Archlinux host
> Cordova 4.3.0
> Xperia Sola with Android 4.4.4  (unofficial)
> Android Simulator - Android 5.0.1 & 4.4.2 
>            Reporter: Tanase Butcaru
>              Labels: html5, video, videodisplay, webview

> HTML5 video tag doesn't work properly on android 4.4 (.2 & .4) webView - only the
audio is playing. With 5.0.1 it works just fine!
> If I enable controls on video tag and enter fullscreen mode then I have video working,
but when I'm out of fullscreen the video screen is black.
> I have android:hardwareAccelerated="true" and I also tried this plugin which is outdated
now (same issue though).
> It doesn't matter if I control video with JS or I interact with the video controls. Tried
both, same behaviour. Tried with all video file formats, no change.
> I know there are similar questions on the web, but all are 1-2 years old and solutions
provided for them are outdated or not working.
> * Using latest version of phonegap/cordova. I have also created a sample app to test
the video tag, thought maybe was something related to my app, but the problem persists.
> Simple test case:
> 1. create a sample phonegap app:
> cordova create helloworld com.helloworld.cdv "Phonegap Test"
> 2. add latest android platform after entering helloworld dir:
> cordova platform add android@latest
> 3. open index.html and add the following after "deviceready" div ending tag:
> <video id="vid" controls webkit-playsinline></video>
> 4. open index.js and add the following inside ``onDeviceReady`` method:
>        //video test
>         var videoObject = document.getElementById('vid');
>         videoObject.src = 'http://demo.touchmediahost.com/kmapp/vid.mp4';
>         videoObject.load();
>         videoObject.addEventListener('canplay', function(){
>             //video can be played!!
>             videoObject.play();
>         })
> 5. Setup 2 AVDs like this: (1) Nexus S with Android 4.4.2 (API 19), Intel Atom x86 and
(2) Nexus 5 with Android 5.0.1 (API 21), Intel Atom x86.
> 6. For each AVD run ``cordova emulate android``.
> You'll see that on lollipop the video is displaying the image and the sound is working
& on kitkat the image is black and it only works on fullscreen mode.
> All files are the default ones; in AndroidManifest.xml the hardware accel si true by
default.
> Also tested on my real device with kitkat 4.4.4.
> I tried these days to change the webview to Crosswalk, but still the problem persists.
Also tried the MediaElement.js with no success.
> The only webview were the video tag works correctly is ludei's cocoonjs (webview plus),
but I don't really like it because it doesn't render the css like it should (only some properties).
