TDA3XEVM: Is it possible to use the remapmerge algorithm for 4Channel camera in independently ?

Hi,

I am testing the remapmerge for 4Channel camera in independently. ( remapMergeLink_algPlugin.c )

Is it possible to use the remapmerge algorithm for 4Channel camera in independently ?

When i use the numInputChannels(2Channel) in the remapmerge, it's working well.

But, When i use the numInputChannels(4Channel) in the remapmerge, it happend the fail.

    Hello,

    RemapMerge is originally written to handle two images from stereo camera. For example, the following is defined in remapMergeLink_priv.h:

    #define REMAPMERGE_MAX_CH_PER_OUT_QUE (2)

    In order to support 4 channels, I think you need to modify several places in remapMergeLink_algPlugin.c, which you may not want to. And I don't want to recommend it either.

    The simple way I can think of now is that you add two RemapMerge Link in your use case so that each RemapMerge link takes care of two channels. Later, you can merge them using Merge link.
