dei link set

hi all .i see the dei link can output 420 yuv ,but now when i link the dei to enc link directly ,it has below error:

so how can i fix the problem

[m3vpss ] 13508: CAPTURE: Start Done !!!
[m3video] 13509: SYSTEM: Opening ListMP [VPSS-M3_IPC_IN_0] ...

another question is that i see the NSF can change the resolution dynamiclly in the DVR_RDK_McFW_Link_API_Training.pdf,so how to do it ,i can not see the resolution in the NSF structure

Log shows encoder is receiving YUV422I not YUV420SP.Only DEI VIP_SC output supports 420SP output. Looks like you are connectin DEI_SC output to encoder.

hi badri ,thanks for your answer,yes i use the DEI_SC.

another question is that i see the NSF can change the resolution dynamiclly in the DVR_RDK_McFW_Link_API_Training.pdf,so how to do it ,i can not see the resolution in the NSF structure

if i want to change the enc resolution dynamiclly ,exception add the dei link before the enc link ,whether some other ways can achieve .

tks

Nsf output resolution will be same an input resolution. If input resolution changes it will automatically adjust output resolution.

If you want to change enc resolution dynamically you need a scaler which means you will have to use either deiLink / scaler link / swmsLink or enable VIP inline scaler in capture link.
