640x480 freescale sample videos

Wierd — Tue, 27 Jan 2009 22:44:06 GMT

Hi all,

I want to try 640x480 videos on my imx27 ads, but i couldnt find a compatible video codec working like the freescale sample videos which are distributed as part of the imx multimedia codecs. But the videos (H264 videos) are 320x240. How can I change the video resolution without affecting the codes ? or where can i find 640x480 videos with the exact video codes supported on freescale board ?

Thanks ,

W.

You can do a gst-inspect mfw_v4lsink to confirm, but I use the following on the MX31 to change: the screen resolution

...! mfw_v4lsink disp-width=640 disp-height= 480 fullscreen=1 !....

Hi Fabio,

Thanks for your reply. The pipeline works fine,,,,with disp-width and disp-height. The problem is when I try to scale 320x240 video to a full screen 800x600. I think there is a problem of upscaling by more than a factor of 2 on imx27. That is why i needed a 640x480 video so that i can scale it to 800x600 because my display is 800x600.

Best,

W.

You can try to download some MX31 video streams: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX31_CODECS&nodeId=0162468rH311432973ZrDR&fpsp=1&tab=Design_Tools_Tab

( Look for MX31_TEST_STREAMS )

As the MX31PDK has a VGA display you should be able to get some VGA stream inside this package.
