How video encoder continunously

[Seoul]

Hello everyone!

I have a ADSP BF533 EZ kit lite and labview embedded for blackfin 2.5 module. I would connect Analog video input(composite video) and capture video frame then display on the my car GPS navigation with A/V input by running Videoecho example.

I was successful to build this example  and i can see video displaying on the navigation. But something i would know more:

 1. the video displayed is not continunously. I can see when i reduce the time delay for display it can change displaying faster. but it alway dispeared a blank frame before starting new frame.

2. I am thinking that mean when Video Encoder actived, Video decoder was not actived? Am i right?. I want to display continunously the video. how i can do?

3. Could i add any image processing algorithm in catched frame buffer then redisplay on the display?.

Here is code for pepople viewing.

Thank you so much for attention and please post your idea if it is possible!

Hello !

It is me again!

I would like to ask anybody that can i use BF_VideoEcoder(decoder)_enable(disable) for ADSP BF537 EZ kit lite. And can i config PPI0 for decoder and PPI1 for Encoder by using AV EZ extender board? beacause ADSP BF533 has only one PPI so that is might be the reason in my above post.

I have ever test with VideoEcho example for ADSP BF537 EZ kit lite by creating new project and config hardware for BF537 EZ kit lite and copy code to new VI and modify LED on/off control VIs for BF537. but te video out but dit not apeared.

Could anybody help me to solve this problem?

Thank you very much!

Hey Seoul,

Is there a big gap between the LED #4 switching of and LED#7 switching on?

Also how long does the blank frame appear for?

hey Aashish!

   The LED switching time and blanking frame apeared depend on the time delay setting for decoder and recoder. Example when we set delay time(300ms is at least) for decoder the blank frame might apear a bout 400 ms.

  My question is how we can display continuously the video stream? is it possible?

 Thank you for your reply!
