Low latency H.264 encoding


Vavooon

Question

Hi. I want to make a device which will receive HDMI stream, encode it into H.264 and stream over Ethernet. Current devices make 200-300ms latency, but FPGA implementations create sub-ms latency.

Will Zybo Zynq™-7000 Development Board be suitable for my needs? I need HDMI input.

 

AFAIK there are IP blocks which do the encoding, but i have no idea how i can otbain them. Is it possible for individual developer, or it would be better to make my own implementation?

Yes, an FPGA should be able to create a device that can capture an HDMI signal and encode it but a hefty amount of latency could be generated by streaming over a network.  Depending on how efficient the network, timing of the FPGA network interface, and the amount of time you sink into the project, you may or may not see a significant difference between current devices and an FPGA.

The ZYBO, Nexys Video and the Genesis 2 can all provide a great hardware platform to accomplish what you are trying to do but there is not an existing project that accomplishes what you are trying to do.  

Best of Luck,

Marshall
