发帖数: 641 | 6 我想在一个机器上把mpg文件stream出去，我来本版询问大家推荐了gstreamer。
我的目的就是我想在一个机器上把mpg文件stream出去，但是这个stream里要能改codec
的属性，比如P－frame的rate什么的。在另一台机器上接受这个stream播放出来。
于是我就试了一下gstreamer。我实在是对linux一窍不通阿，总遇到error。
google出来的几个结果我也不动阿。
比如：我在当前文件夹下，有个子文件夹叫做video，这个video文件夹里面有一个视频
叫做1.MPG。我现在就是想把这个视频stream出去，我就按照google的结果试了一下：
gst-launch v4l2src ! video/1.MPG,width=640,height=480,framerate=\(fraction\)
5/1 ! ffmpegcolorspace ! jpegenc ! multipartmux ! tcpserversink host=192.168

发帖数: 641 | 8 谢谢！这个works。
在另一台ubuntu PC上，我用
“gst-launch tcpclientsrc host=130.160.47.62 port=5002 ! multipartdemux !
jpegdec ! autovideosink“
接收这个stream，能播放。
但是我的目的是：
1.MPG这个视频的framerate是25，但是我想把它有时候改成20，有时候改成10。甚至还
要更改I-frame，B-frame和p-frame的rate。那这该怎么实现呢？
有人说要“put a videoscale element between decodebin and the caps filter”，
那我具体啊该怎么做呢？
谢谢！！！ |

jpegenc ! multipartmux ! tcpserversink host=192.168.2.1 port=$portNumber
把本机的一个mpg视频stream出去，能在另一台linux pc播放这个stream。
这种方法可以更改frame rate。
但是没法实时更改。我想要随时更改这个frame rate。
有人回复我说用python就可以了。谁懂怎么写这段代码呀？帮帮我吧！谢谢！ |

Even though the journal impact factor (JIF) is only a measure of a journal's
average citation frequency, it has become a powerful proxy for scientific
value and is being widely misused to assess individual scientists and
research institutions, say the DORA framers. The JIF has become even more
powerful in China, India, and other nations emerging as global research

Though the CG sequences and storyline bits are a bit thin, when they're

The sometimes inconsistent framerate and slightly wonky ragdolls and
collision detection are the only thing detracting from what is an otherwise
gorgeously depressing, incredibly imaginative world.

Great stories and fantastic behind-the-scenes content are only marred by
poor video quality.

While they don't hold a candle to the likes of Uncharted 2, the games look
great in HD, especially God of War II. The crisp framerate is also very
welcome.

It's no secret by now that Bayonetta on the PS3 is little more than a less-
than-stellar port of the leading Xbox 360 version. Long loading times, poor
framerate and altogether murkier graphics stand out to make Bayonetta
inferior on the PS3, but it's now being reported that Western PS3 fans might
not suffer as much as Japanese ones.
According to Gamekyo (translated by Wearetheinternetz), Sega and Platinum

price I could find right now, and has no rebate or cashback hassles to deal
with. $649 out the door with free shipping and no tax. (at least in CA)
Great balance between performance, size, price and battery life.

对小津在电影上的成就几乎一无所知,
这个名字的了解还是从WIM WENDERS的一本摄影诗集"ONCE"中开始,
看到你们说起,把这本书又翻出来,摘抄书的扉页上面的原话
"This book is dedicated to Yuharu Atsuta.
He lived from 1904 to 1992.
His entire professional career
he worked with Yasujiro Ozu,
on all his movies,
first as assistant cameraman,
then as a framer,
then as a camera operator,
and finally, for twenty years, as director of photography.
When Ozu died in 1962,
faithful Atsuta stopped working
that very year."
读到后,第一件事是GOOGLE这两个日本名字,才知道Yasujiro Ozu是小津 :)))
