View Full Version : xtype video on ANDROID - support please clarify

Friend,

Without being required to pay $300 for a simple answer, can I ask someone from Sencha to clarify what is a core requirement for many apps in our multi-media world.

is it actually possible for Sencha Touch to render video for Android devices?

There's a lot I like about Sencha Touch, though it's a steep learning curve. But, if the answer to the above is no (and one user recently stated to me - 'yep, I get round it by hiding the video menu item from my android users') then there's a problem.

Of course everyone likes the iPhone, but there are more Android device users than iPhone these days and it seems that the sencha xtype 'video' doesn't mark up the video tag properly for Android.

Can I ask for a response from the support team (who I hope do actually look in this section from time to time), so that I, and many like me, can either solve this or move on.

Thanks
Allister

The problem we have noticed is that Android doesn't really support things as well as we would like. iOS is still king by a long shot. Video is one of those things Android doesn't do the best on.

Hi there - thanks for the reply.

Yes, I can see that Android is not that helpful - so...is there any workaround or are you saying that, until Android adapt, video will never work on that platform, through Sencha Touch?

Thanks for your help

I dont know in Android 3.0, but till 2.3.3 the Android Browser simply dont support video tag, this is the first, so to view a video in sencha you have to do location.href ="yourvideourl" that will open the native video player. In phonegap i modified the childBrowser plugin in order to stream a video.Second in order to strream a video on android you have to add moov atom at the beginning of the video, i do this with ffmpeg (qt-faststart) server side.

Thanks Steve.

Just to clarify what you are saying - the location.href ="yourvideourl" is to reference an external webpage that you show with the phonegap childbrowser (never yet got that to work in android myself, though IOS is fine).

And if I wanted to hold the videos as local assets rather than call a web page? Is that possible?

No, the location.href ="yourvideourl" is your video url not a webpage location.href ="http://yourdomain.com/test.3gp", this is for webapp, in Phonegap is different because location.href dont work and it's because you have to use the plugin. If you hold videos on local asset you dont need the moov atom at the begining of the video and you can still use the childBrowser plugin

just do location.href="myvideo.mp4"; and it will open up the native video player

steve1946,

How did you get videos to work on Android in Phonegap using ChildBrowser?
Did you enable hardware acceleration?

I was only able to get videos working after enabling hardware acceleration but then my Sencha CSS transitions got all choppy.

If you have a solutions please let me know how you did it.

The childBrowser plugin simply open an url from within the app, if the url refers to a video file then the native video player is invoked and the video is played. You are speaking about Android 3.0, this is a bug of the Android Browser in 3.0, if you enable hardaware acceleration in the AndroidManifest.xml the css are broken, but with childBrowser you open the video in native video player so you dont need hardaware acceleration.

Well I actually open a Sencha app in ChildBrowser that has a video embeded in a carousel. So I'm not opening the video directly.

childBrowser modified plugin in order to direct open video in native video player (the mod in red). Otherwise the original plugin will prompt if you wnat to play the video in the native videoplayer or in the browser.

Mitchell - I noticed you were still referencing an MP4 video file. Are you saying that you believe that codec will work with Android devices, or is that only IOS?

In my experiments, I was able to get a regular mp4 file that I use on iOS to work on Android version 2.3 and up.

In 2.2 and 2.2.1 is not working i use 3gp video file or mp4 file but with the moov atom, i'm referring to streaming file, for local asset is different

OK - just to clarify then - local video assets, which can be 3gp or mp4 (h.264?), can work but only in 2.3 upwards. Not 2.1 or 2.2?

Thanks for bearing with me....:)

For local asset you can use mp4 or 3gp, but bw aware that for mp4 (h264) google will drop support for this encoding due to copyright issue, is because google has webm video format:
