Hi Kian,

Thank you for your response, I did not see it till now. I am attempting to do these calculations, but I am a little confused on how to calculate for all 4 frame buffers. I'm assuming I would calculate for 1 of them and multiply it by 4, but while doing this I realized I forgot to mention we are sending static images as of right now. The input is a RGB gstreamer pipeline with the default smpte color bars pattern that is in a paused state so the bandwidth shouldn't be exceeded. I could understand this becoming an issue when I try to input a RGB live feed in playing state into the frame buffers, but this should not be the problem while the pipeline is in a paused state. Also, while in paused state the frame rate does not apply, so I am not sure how I would calculate for the paused frame rate.

Thanks

Evan
