i.MX53 IPU VDI Channel path

[cader]

Dear all,

i.MX53 IPU supports many channel paths as mentioned below where VDI involves.
1. CSI –> VDI –> MEM
2. MEM –> VDI –> MEM
3. MEM –> VDI –> IC –> MEM
4. CSI –> VDI –> IC –> MEM
5. and so on.
 
We want to validate the second channel path (MEM –> VDI –> MEM ) mentioned above which is applicable for type of de-interlace application.
Please let us know MEM –> VDI –> MEM path is tested and if so, please provide the test application which just read from interlaced video file and outputs the de-interlaced video in another file.

Please share the idea or any one did the same.

Thanks in Advance.
Cader.

Hi Cader, I think you can reference to vpu_unit_test code, which can be found in BSP unit test code.

The test application can do de-interlance in MEM->VDI->MEM(Frame buffer).

You can also reference to my blog: http://imxcommunity.org/profiles/blogs/1080i-de-interlance-support-for-imx53-based-on-l2-6-35-11-09-...

Do you have solved the problem?I want to work on CSI->VDI->MEM.But it failed.In kernel_imx/drivers/media/video/mxc/capture/,there has CSI->PRP->MEM example.I modified it but no success.If you have any idea,please contact me.My email is 568075896@qq.cm.Thank!
