I did a test on my intel i7-6600U CPU @ 2.6GHz with 16GB ram - One RabbitMQ broker started with: $ docker run -it --rm --name rabbitmq -p 127.0.0.1:5672:5672 -p 127.0.0.1:15672:15672 rabbitmq:3-management - 1 client streaming to the broker (1280x720, 30fps, bitrate: 1236kb/s) $ ./ffmpeg -re input.mp4 -codec:v copy -an -f mpegts amqp://localhost - 300 clients connecting to the broker and writing the output to null: $ ./ffmpeg -i amqp://localhost -codec:v copy -f null - - 2 clients playing the stream with ffplay $ ./ffplay -i amqp://localhost All the connections were visible on the broker monitor, and streams were running at speed ~1.0x At this point all my cores were close to 100%. -- Andriy _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
