Question

HTML5 not working on iPad, multitude of issues, looking for solutions

Hello,

I'm trying to test the possibility of publishing trainings to HTML5 for use on iPad or iPhone. In our first test, we put the HTML5 publish up on an LMS and accessed it through an iPad and iPhone. Via the iPad we used Safari. This is what happened:

First three slides did not appear (first has a single image, second has an f4v video, third has an f4v video).

We had narration throughout which did not play at all. Audio files are in WAV format.

Overall very slow

Crashed on one slide

Slow navigation on the Table of Contents.

Any suggestions about why we may be having these problems? Should we be using a different browser? Conver the F4V videos to something like MPEG or AVI? Anything helps, thanks.

    Hello,

    When publishing to HTML5, all the videos are converted to H.264 encoded MP4 videos by Captivate. These videos play fine on iPad. In general, if the videos are not even showing up, you might want to try one simple thing. Take the MP4 video (you will be able to find it inside the published contents) and put it in your Web Server. Now request this video alone in the browser. If the video plays fine there, then you need to contact me :-) asgarg at adobe dot com. If the video doesn't play then you need to check your webserver. Apart from basic configuration for serving video files, iPad needs specific support from the webserver for media files (video and audio) -  (http://developer.apple.com/library/safari/#documentation/AppleApplications/Reference/SafariWebContent/CreatingVideoforSafarioniPhone/CreatingVideoforSafarioniPhone.html#//apple_ref/doc/uid/TP40006514-SW6) . If you were seeing a grreen rotating circle for a long time, then it could be web server problem only. Also, you mentioned that the audio also didn't play, that too indicate in this direction only.

    Another thing, just to isolate the issue, you can try with few slides having simple objects and no audio/video. If that is working fine, then we will know that we need to just configure everything proprly for audio and video.

    Assuming this works and you got the content on iPad, if you still feel that content is running slow, then check-off the "scalable HTML" option while publishing. iOS does not behave well with the scaled contents that are changing.

    Thanks,

    Ashish

    If you want Apple-Mobile device delivery, MP4 is your only choice (at least, for now) - with h.264 encoding.

    Yes and no, Erik. I did learn I needed to change the video format to H.264 MP4 encoding/formatting, and I recently did that. After another test, those videos still don't work. Any other ideas?

    Hi RiskLMSspecialist,

    Videos with codec : On2VP6 are supported for HTML5 output.

    If you are publishing the videos to the local server, Local Server should be configured to play mp4 files.

    After following the above instructions, if you are still facing the issue please share the sample project with us.

    Upload the sample project to acrobat.com and send the link to mahajan@adobe.com

    Thanks,

    Mayank

    f4v videos are Flash videos, aren't they? I don't know if Cp will convert them automatically. I thought you needed to use mp4 formats. Can you try converting them to mp4 and then republishing. It would be interesting to see if it makes a difference. I don't know if not being able to render the movies correctly may be affecting the performance of the overall project.

    After talking to an Adobe support person, apparently F4V files won't play on iPad. I'm warry of rendering videos to MP4 because of file size. That's the whole reason I did F4V in the first place...

    Have you tried playing with the settings when saving the MP4 file? I was able to cut my file size in 1/2 but changing some of the settings (i.e. bitrate) and they still looked good.
