Media Control Framework Video Test Applications for OMAP3530 using 2.6.37 or above Kernel

Other Parts Discussed in Thread: OMAP3530

Dear all,

Where can I obtain test application that is media-control Framework aware or compatible to stream from MT9V032 camera sensor and output to the LCD touchscreen display?

Previously, I can do "export DISPLAY=:0.0" and "gst-launch v4l2 ! xvimagesink" to get the camera stream to display on the LCD using 2.6.34.

But with MC-framework in newer kernel, what test application can I use to do the same to display the camera output to LCD screen?

Many thanks in adv.

James

    Did you get MC driver from SDK? In that case you should get relevant applications from the SDK only. If SDK doesn't have application you are looking for, you might need to write a application yourself. I am not sure where OMAP based applications are present. I am providing link to dm36x based MC applications which you can use as a reference.

    Hi,

     

    I'm not using the SDK. Instead, I'm using Openembedded on my Overo FE (OMAP3530) board with MT9V032 camera.

    I read from TI site that OMAP35xx PSP 04.02.00.07 has migrated to MC framework and at the bottom of the page talks about 2 sample application provided.

    MMAP Loopback Application (saMmapLoopback.c) and USERPTR Loopback Application (saUserPtrLoopback.c).

    Where can I get hold of these 2 applications?

     

    As for your provided link to dm36x based MC applications, will it work on OMAP3530?

    I need one simple test application that can does streaming like gstreamer to the LCD touchscreen.

     

    Thanks in adv.

    As page talks about SDK, I believe applications are in SDK

    .

    They wont, you need to change them to work for OMAP

    .

    Sorry, for dm36x, we don't have that application ready. This is because we need to support camera->LCD loopback.

    Can you point me to the page to get the proper SDK?

    TIA.

    Can I just cross-compile these application that you pointed out for OMAP?

    I'm surprise that there are no readily test application that is MC-aware and can do playback on the LCD screen.

     

    Thanks.

    James,

    Example applications for AM/DM37x with media controller framework (2.6.37 kernel) are currently hosted on Gforge. They are also released as a part of the SDK 5.02 installer with CCSv5 support.

    Hi Punya,

    Thank you for the link to the samples for AM/DM37x.

    What about the samples for OMAP35xx as described in the here.

    Thanks in adv.
