only a part of screen(352 X288) in the center.

I want to decode the CIF video stream which is encoded in H.264 on DM365 platform.

But The video is displayed not the whole screen(720X576) only a part of screen(352 X288) in the center.

How could I make the output of decode be full of the screen?

Resier?

But the resizer is work in continuous mode. The resizer API is not support in this mode?

Or other ways?

I use the decode demo in dvsdk_2_10_01_18.

If the original stream you are decoding is in CIF resolution, then yes you will have to use resizer to up-scale it to NTSC for full screen display (assuming you have NTSC display). Unfortunately, this scenerio is not covered by our encode demo (you can run ./decode -h to display options supported), so you will need to make appropriate changes. Most likely, the chages should take place in the decode demo or dmai user space library components of our software and we provide all the source code for these.

aside from demos, there are a few examples under PSP_xx_xx_xxx/examples/dm365 directory, including a preview_resizer example.

Hi Juan,

Thank you for your help.

I think only someone from TI can resolve this problem.

It's so common.

Hi Juan Gonzales,

I read the preview_resizer example and find the example input is YUV422 format.

But I want to upscale from 420 CIF to 420D1 .

Dm365 decode only support XDM_YUV_420SP format others are not supported as mentioned in "h264_decoder_dm365_userguide.pdf( page:54-55).

I try lots of ways and failed after failed.

Could you spare a little time to solve this problem?
