Hi UkVOSklF,

Uncompressing/compressing 9 video, especially if the resolution is big use CPU.
You may try the -o option that reduce compressing stuff but reduce format adaptation between RTSP stream and WebRTC stream.
Another approach could be to implement hardware encoding/decoding.

Best Regards,
Michel.

hi
How to configure the -o parameter in docker compose,

services:
webrtc-streamer:
network_mode: host
image: mpromonet/webrtc-streamer:latest
restart: always
ports:
- 8000:8000
volumes:
- ./config.json:/app/config.json

Hi Garyguosha,

May be using https://docs.docker.com/compose/compose-file/compose-file-v3/#command ?

Best Regards,
Michel.

hi mpromonet

I'm really sorry, but my configuration has been wrong. Can you configure an example.

[Garyguosha]

hi UkVOSklF

Have you solved it。

[mpromonet]

Hi @Garyguosha

I think if you read the docker-compose documentation and make some tries, you will easily find the syntax to add -o to the command list. This is not specific to this project and there is plenty of examples on internet.

Best Regards,
Michel.

Hi Garyguosha,

Please could you reduce spoiling issues that have nothing to see your problem. I already deleted several of your post that cause confusion about the initial issue speaking about something different...
Mixing runtime subject with build one.... what is the link.... -o is a runtime option that enable NullCodec, nothing to deal with build args of docker image.... it is hard to follow what does you mean...

Best Regards,
Michel.
