gop_size: -1 # [max 256] The GOP size determines the maximum distance between IDR/I-frames. Very high GOP size will result in slightly more efficient compression, especially on static scenes. But latency will increase.

chunk_size: 16084 # [1024 - 65000] Stream buffers are divided into X number of chunks where each chunk is chunk_size bytes long.
