Hi,Guys.
Device is DM365, DVSDK-demos is 4.0.0.21, DMAI is 2.2.0.14 .
Now I can display video in a 800x480 LCD, but since the display thread is using framecopy, the video can only be shown a part of it.
So I decide to use the resizer module ,and show the whole video in LCD, but I met some problem.
Since it's the first time for me to use resizer, I change the output to TV, not LCD, the hardware connection is :【PAL input】->tvp5150->DM365->【TV-PAL output】.
here is my code display.c from decode demo:

since the resizer_config need a BufTab handle from source, I provide a api from video.c to get the input BufTab:
| static BufTab_Handle g_video_buftab; BufTab_Handle getVideoDecoderBufTab(void) { return g_video_buftab; } |
And set the variable to vidoe.c's hBufTab after it's created.
/* The codec is going to use this BufTab for output buffers */
Vdec2_setBufTab(hVd2, hBufTab);
g_video_buftab = hBufTab;
=====================Now here is the problem==========================
1、if I donot set the colorspace of BufTab from video.c to UYVY ，the resize_config() fail:
//BufferGfx_setColorSpace(BufTab_getBuf(getVideoDecoderBufTab(), 0),ColorSpace_UYVY); // comment this line
report: davinci_resizer davinci_resizer.2: rsz_validate_out_pix_formatspix format not supported, 9
So I uncomment BufferGfx_setColorSpace(BufTab_getBuf(getVideoDecoderBufTab(), 0),ColorSpace_UYVY); now it config OK.
2、resize_execute() fail. no matter whether I comment "BufferGfx_setColorSpace(hSrcBuf,ColorSpace_UYVY);" or not before calling it.
report:decode: linux/dm365/Resize.c:334: Resize_execute: Assertion `(rsz.in_buff.offset & 0x1F) == 0' failed.
Aborted
It seems the offset should not be zero???
I have check this post:

but still have no idea, could you provide more information how to use it?
