TDA4VM: Is there a difference between the encode node in tiovx on psdk7.2 and psdk7.3 ?

Part Number: TDA4VM

Hello,

    I want to use the encode function, so I used the encode node in tiovx to develop the application(I used the capture node, convert node and encode node in the application).

    The image size output by the capture node is 1920*1080,and the image format is YUV422. I use the image conversion node to convert the image format from YUV422 to NV12, and used the encode node to ouput h264 file. 

    I used identical Camera driver on psdk7.2 and psdk7.3. However, the h264 file output on the psdk7.3 version has a color distortion problem and the h264 file output on the psdk7.2 version is normal. So I would like to ask what is the difference between encode node on psdk7.2 and psdk7.3, and Whether the encode default parameters have changed.

    thanks,

    rchen.
