I streamed video successfully through RtspServerFromFile and I want to know streaming frame rate and resolution.

Hello,

The resolution is the video file resolution and the frame rate is cap to video file framerate but you can add a callback that notify you fps:

    rtspServerFromFile.setFpsListener(new FpsListener.Callback() {
      @Override
      public void onFps(int fps) {
        //called each second while streaming or recording
      }
    });

If you want you can get video file resolution using android API: https://stackoverflow.com/questions/8000978/is-it-possible-to-get-the-resolution-of-a-video-in-android/27437526

Hello,

Did you check with others files?

FPS depend of your file and your device performance. I'm using a decoder to extract frames from the file and encoding it in H264 so if you have a problem in this proccess (device performance) your fps could change a bit in few moments.

Also, fps callback is an estimation fps but this could change a bit and could add few fps to the next logs depend of the timestamp but if you calculate the average this should be really similar to the real value.
