TDA4VM: Questions for about camera multi.

Hi ,
We have implemented an raw  format and an yuv format camera display. and it is implemented with two gprph.
so if i want to integrate two graphs into one graph, is it feasible?,
Look forward to your reply.

    we used  two multi.out  programs to test two different formats of cameras. 

    The first process runs the ram format camera program,the other  process runs the Y program,
    and i found the second running process will stuck in app_verify_graph function . So I doubt it can‘t be used like this.
    If there are two different formats(raw,yuv) of cameras, how to use mutil.out ?

    Tao,

    What you are trying is not supported in 7.3. For app_multi_cam we need all the sensor types to be the same. Connecting different sensors on the same graph would be coming up next but let me check with an expert on availability.

    Regards,
    Shyam

    OK, I'll wait for your reply.

    Hello Tao,

    Connecting different sensors on the same graph is not supported.

    Hi ,

    How can I support two cameras of different formats running at the same time ?

    Hello Tao,

    It seems like process #2 is getting stuck. Is this using Raw format camera or YUV format?

    Regards,

    Hi Mayank Mangla

    It is YUV format camera.

    so I have some question.

    When different format types of  camera modules are connected at the same time, which of the following cases is supported:

    1) The same process:

       process 1-----> ram format camera capture ---->graphA ---->csi0

       process 1 ----->yuv format camera capture----->graphB ------>csi1 

    2) The different process (two process):

       process 1-----> ram format camera capture----> graphA ---->csi0

       process 2 ----->yuv format camera capture ----->graphB ------>csi1 

    1) In one process,  raw module (csi0) through graph A and YUV module (csi1) acts through graph B

    2) In two process , the one camera module of raw format (csi0) and  one camera module of YUV module (csi1)  that used different graph cantrol them.

    So Do you have any good methods or suggestions？

    #2 is the preferred option

    For YUV format, VISS and AEWB nodes should not be created. VISS can process only RAW format images.

    sorry , #2  is the raw format camea. 

    This is a log and config camera.and I suspect that some resources interact,please help me check it,

    What happens when you start process #2? Does the first process continue to run?

    Is process #2 also trying to access display? Display can be accessed only by  process.

    Hi ,

    Thank you for your replay .

    The first process runs in the background and then run the second process.

    When the second process is running, both  processes are stuck.

    Both processes need to be displayed on one screen.

    So I  want ot know why it got stuck?

    >>Both processes need to be displayed on one screen

    This is not supported. Only 1 graph can access display node. Most probably this is the reason why it is stuck.

    In other words, using two processes to run cameras with different (yuv,raw) formats  does not support displaying the same screen.
