最近為了在ubuntu上搭建流媒體服務(wù)器，目的是為了在ipad上觀看電腦上的視頻并且不用將視頻文件下載到本地，這是找到的編碼相關(guān)的資料~

For HTTP pseudo-streaming to iPhones, and RTSP streaming to other mobiles, .mp4 files need to be correctly encoded.?

Normally a .mp4 file has its data information included at the end which, if streamed, would require the entire video to be downloaded before playback can begin.?

Videos can be correctly encoded using ffmpeg but for a less stressful process, using a graphical interface, install Handbrake. Unfortunately there is no longer .deb package available for Ubuntu, but the?PPA?may be added to Synaptic:?

deb http://ppa.launchpad.net/stebbins/handbrake-snapshots/ubuntu lucid main
deb-src http://ppa.launchpad.net/stebbins/handbrake-snapshots/ubuntu lucid main?

with the signing key: 1024R/816950D8?

Or use:?
~$ sudo add-apt-repository ppa:stebbins/handbrake-snapshots?

Update the package list:?
~$ sudo aptitude update?

and install Handbrake?
~$ sudo aptitude install handbrake?

Handbrake will now be available in “Applications > Sound & Video > HandBrake”?

Choose the output format that you require, making sure to select the “Web Optimized” box as well.?

To complete the encoding time data must now be added to the .mp4 file. Install MP4Box using:?
~$ sudo aptitude install gpac?

and run:?
~$ MP4Box -hint YOURFILENAME.mp4?

The .mp4 file can now be uploaded to the server for streaming??

If you are using HTTP streaming, for instance to an iPhone, ensure that your server does not have the Apache module “mod_h264_streaming” enabled as this interferes with HTTP progressive block requests.
