How to manipulate the stream in real time? #10

Open guangjieguo opened 5 months ago

guangjieguo commented 5 months ago

Hi,

I am using pyrtmp for a rtmp server. It works great for video upstream and save it as a flv file. But I want to manipulate the frames in real time. How can I do that?

Thank you!

You have to pass video frame into video processor. For example OpenCV or ffmpeg and do whatever you want. Remember that video frame you received is chunk of compressed video stream not a still image

This is example of piping video stream into ffmpeg https://github.com/Eittipat/pyrtmp/blob/master/example/demo_ffmpeg.py OpenCV can be done in the same way

@Eittipat Thank you for your kind reply. I still don't know how to customize your code to extract frames. I don't know which variable contains the latest chunk of stream and how to decode the chunk into frames. Would you update an example that can extract frames and show them without saving the stream into a flv file, please? That will be very helpful to me. Thank you very much.

There is a specific definition of frame in on_video_message, but I'm still trying to change it to work with OpenCV
