I did a test video using the Fabio Sonnati's settings (the same I posted in the beginning).
The best I could find to stream video. It's realy amazing the quality we can get with only 250Kbps. Look at the video: http://www.thiagoprado.com.br/teste.mp4 |

Since my videos are basically one person talking at low motion scenes the 250Kbps are fine. But in some motion scenes the image get blocky. Is there any setting in x264 that can avoid blocky? Thanks |

Also, using such a low deblock setting isn't helping either. |

There's no reason to minimize the VBV buffer size. You just want it no bigger than the player's HW is providing. Last edited by Guest; 19th February 2009 at 04:49. |

If he has a buffer of, for example, 10 seconds, that means you have to wait 10 seconds before you can tune in to the stream. |

His gop is already 10 second long. I think he can afford a slightly longer VBV. Furthermore, in the OP, why --level 51 ?

Thanks, Guys
I increased the maxrate to 700 and the bufsize two 1400 (two seconds of 700Kbps peak). Since I'm using a prebuffering of 5 seconds and the flash media server 3.5 now have the dynamic buffering, I think will be fine. What is GOP? |
