deinterlace video with omap3530

Other Parts Discussed in Thread: OMAP3530

 

What is the best way to deinterlace video when using an omap3530 with the ti-gstreamer plugin?  The only thing I can come up with is resizing the incoming 720x480 down to 360x480 (throw away every other line), then resize it again up to 720x480 to get the aspect ratio back to normal.

thanks,

chris

    Chris,

    Here is a response i received a little while ago from a colleague (Thanks Punya)

    Please refer the capture driver user guide at http://processors.wiki.ti.com/index.php/UserGuideOmap35xCaptureDriver_PSP_03.00.00.05

     Capture example applications are available in the PSP release package at src/examples/video folder. Please refer to the saMmapLoopback and saUserPtrLoopback applications. Here driver/user allocated buffers are used to capture video data from the active i/p and displayed on the LCD. The latest stable PSP version is 03.00.01.06 available at ftp://ftp.india.ti.com/PSP/Releases/ODC/OMAP35XX_GIT_PSP/AM35x-OMAP35x-PSP-SDK-03.00.01.06.tgz

    Hope this helps.

    BR,

    Steve

    Hi Steve,

    There is good info in there, but I don't think there is anything in there on how to de-interlace incoming ntsc video.  

    I think some of the other TI parts on de-interlace support, but apparently not the OMAP?

    Are there 3rd parties which make dsp algorithms for deinterlacing that can run on the OMAP?

    Thanks,

    Chris
