Stream #0:0: Video: h264 (Main), yuv420p(tv), 640x480 [SAR 1:1 DAR 4:3], 24.42 fps, 14.75 tbr, 1k tbn, 48 tbc
Stream #0:1: Audio: speex, 16000 Hz, mono, s16, 42 kb/s

You can download any video file from mygirls.party and to get more info.

I don't use rtmpdump. I'm using my own fork of python-librtmp

Ok, get it. At least now I'm confident to say you know your stuff.
I choose a different approach and "patched" rtmpdump to support mfc.
