My application requires two video cameras, one at VGA 60fps and second at 720x480 at 30fps. I intend to connect the VGA sensor to the Camera ISP parallel video input port and the 720x480 sensor to the Camera ISP MIPI compatible serial video input port. The Technical Reference Manual says only one of the video input ports can be streaming to the IVA for video encoding. The other video stream has to be written to memory.
Can the IVA on the DM3725 encode both the video streaming directly from the video input port and the second video reading from memory simultaneously?
If so, is there significant overhead for the IVA to switch between encoding video streams that will effect encoding performance? i.e are there pipelines that need to be flushed out, pointers and parameters that need to be modified, etc.
Is there any performance/benchmark data of the DM3725 doing H.264 encoding of 720x480 30fps?
Thanks.
