Vufroia Video playback issue

By anbu on Tue, 04/08/2014 - 16:11

Hi,

I have vuforia playback issue only in the latest IOS devices - iphones5s and Ipad Air.We have been using different dimensions for m4v files.It play like a charm in all android and IOS devices except Iphone5s and IPAD Air.The frame rate drops to 3FPS and the video lags in the two mentioned devices.

Iam using IMAC-Mavericks-Xcode 5.1-Unity 4.3.4 pro-Vuforia 2.8.7

Initially i thought there was a video codec issue in the latest devices.Ive tried Imovie and handbrake but no luck.Finally when i tried to resize the video to 640x360(similar to sample video).It worked like a charm.But the video we are using needs 850x350.Is it something to do with the aspect ratio ??? which is fixed in latest ios devices withrespect to the vufroia ??????

It would be great if someone could shed some light on this issue ?

 

Thanks

Antony

 

 

 

Try playing the video natively on iOS using its own video player and see what happens.

The VP code uses the underlying playback mechanisms of iOS so if there is a problem it is likely to be something at the iOS level, as indicated by the fact that it is iOS5s and Air specific.  

Thanks for the reply!

is there any solution for the FPS drop bug in iphone5s and IPAD Air  for diff dimesnion videos?  could you reproduce the bug ? does the development team is aware of this bug ?

 

thanks

I am not sure this is a bug per se.

If you PM me with a link to a project I can try to investigate, particularly if this is device specific.

I've  involved this issue too , my video is 678 × 384 and i'm using iPad Air iOS 7  , vuforia 2.8 , unity 4.3.0.

Hi,

File uploads are prohibited in our company.Is it possible for you to resize(increase) the same vuforia sample video dimension using some convertors etc...and then attach a FPS script to any gamobject and see the result.Plz juz give it a try.

When I tried to build it in Unity 4.3.4 I got linker errors that indicated a problem in the PostProcessBuildStep.

This would imply that you are using an older version of Vuforia.

Please upgrade to the latest version as this is the only one that is supported.

I have the same issue. On iPad Air and iPhone 5s FPS drops. I think the problem in 64-bit processor. Can anybody rebuild vuforia sdk for 64-bit?

is there any solution for this problem ?

 

Vuforia Video play back - 640x360 dimension seems to be the restricted size for 64 bit architecture IOS devices.The Rest loses FPS.I even tried 360x640..still loses FPS.
