hi all,

     i am using imx535qsb board in that we include a camera interface application ov5640. we have captured the resolutions 640x480 and 720p video. when i tried to captured the 1080p video my application[mxc_v4l2_capture.c] does not supports it prints the following error message can anyone help me with this error message

ERROR:

VPU encoding can go up to 720p@30 for some codecs. So you will not be able to encode 1080p stream. (I just double checked it on VPU specifications)

Does your usecase needs the encoding?

[shanmugamsundar]

hi daiane,

       yes, i also checked the vpu specification. is there any chance to encode 1080p in imx535 qsb and this also need to my usecase

     sorry for the delay , last four days i am out of station today only i came

[daiane_angolini]

I´ve never heard about 1080p encode on imx53.

Even if you was able to encode 1080p with qsb, i think it will not get a feasible performance.

[shanmugamsundar]

yes, you are correct we cant able to encode the 1080p video in imx qsb, we kept this process in hold. let see

Thanks

If 1080p encoding is needed, please consider mx6q.

Instead of encode it into a file. Are you able to preview it? (mfw_v4lsrc -> autovideosink)

[shanmugamsundar]

no i cant ,  Also i tried by taking the encoder in command but it remains same

Regards
