Hi,
I’m searching for a good explanation about the qp-range parameters for omxh264enc since it seems to affect the stream quality very deeply.
I have a 12.5FPS 1280x720 stream and I would like to have a good quality for an highly dynamic scene with the minor possible latency.
The video is streamed in udp-multicast.
Thank you
Walter
Please refer to H.264 quantization parameter - Vcodex
The QP values are within min and max configuration. You can adapt it according to bitrate and framerate.
Default configuration is at /etc/enctune.conf
This is what I knew… but how? What does affect latency? What does affect quality?
Hi Myzhar,
You can check QP value of each frame via JM decoder Karsten Suehring
Low QP value brings high qualiy and high bit rate.
