I want to capture low latency h264 at 1080p30 from a 3G-SDI or HDMI source. On FPGA based systems, the encoder minimizes latency by generating a NAL byte stream. These byte streams don’t have to wait the full 33 ms for the entire frame to be read in. Instead, it can operate on several lines at a time. By doing this, the h264 stream has sub-frame latency.
Is the iMX6 h264 encoder capable of this? What is the video encode latency with this configuration?
