I have tested with different settings all the result is about the same delay of 500 ms.
Tests:
create_video_configuration set to buffer_count=1, Delay of 500 ms
create_video_configuration set to encode="lores", Delay of 500 ms
H264Encoder set to different bitrate only image quality is affected with delay of 500 ms
H264Encoder set to iperiod=1, default is 6 but the change do not affect the delay
picam2.start_encoder set quality=Quality.VERY_LOW and VERY_HIGH but the change do not affect the delay
Is there a other way to stream direct to VLC with latency below 100ms?
