Help for Camera Recorder

[Zenger1978]

My project is based on imx535+wince7(2011_05_smd_bsp). There are three main problems: 1、How to get Handle of the device "CAM1:" which loaded by IFileSourceFilter->Load(L"CAM1:",&Media_Type) ? 2、Where can i find the Interfaces of FSL base filter , CLSID_FSLVPUENC、 CLSID_FSLAVIMUX 、 CLSID_FSLFILEWRITER and so on .... 3、In FSL capture filter Graph, which filter can split two pins,One for preview,the other for capture.

Hi,Prabu Kumar, Thanks for your answer! Could you help me to test your Samples on IMX53 SMD platform ?

[Zenger1978]

I remove "FSL_MMF_MUXER_AVI" and "FSL_MMF_VIDEO_CAPTURE", but the DDrawTest still fail at Line " CHK( pVideoRenderer.CoCreateInstance( CLSID_VideoMixingRenderer ));" 。

[Zenger1978]

I also remove item " FSL_MMF_VIDEO_CAPTURE" .

[Zenger1978]

Thanks.The following is the VMR content in my reginit.ini .Next i try to remove the FLS_MM from the OS as you tell me . I don't how many catalog items would be removed ! FSL_MMF_AVI_MUX_TEST  & FSL_MMF_APP_AUDIO_CAPTURE, and so on ...

It looks like Freescale Multimedia framework removes the VMR from the registry.So try removing the FSL_MM from the OS and test the camera application.

[PrabuKumar]

Did you given “Clean Sysgen” after selecting the DShow VMR from the catalog items?

Also search for “VMR” in your reginit.ini file on the release directory of your OSdesign,and check whether registry related to VMR are present in that.

[Zenger1978]

Wince7.

[Zenger1978]

Thanks for your answer . I have added SYSGEN_DSHOW_VMR in my catalog item. Are there others renderer components ?https://community.nxp.com/discussions/83-render.PNG" target="_self

[PrabuKumar]

Are you trying with WinCE 6.0 Or WEC7? If you are trying with WEC7,check whether you have the renderer component from the catalog item.

[Zenger1978]

Sorry， I can't  run your sample. Debug Port msg is "Builing the graph failed hr=0x01 ". I find out It fail at Line "CHK( pVideoRenderer.CoCreateInstance( CLSID_VideoMixingRenderer ));" ? what's wrong with it? Thanks.

If you had developed DirectShow camera driver for your camera sensor,then you can use the following sample application to test the same.
